Types of electrical cables and wires. Basic Definitions for Cable and Conductor Products

House and plot

I will make a reservation immediately. This article is not intended for those who do similar issues professionally. In this case, do not waste your time! Information of this article is designed for an ordinary consumer who sooners or later has to solve the issue of filing and distributing electricity at home, in the country, etc. Of course, you can contact the specialists who will qualify for this issue. But if it is connected with significant material costs for you, take advantage of the information of this article and see that everything is not so difficult. "Do not burn the pots of pots !!!".

In order for the selection of the cable or wire is correct, you must perform several conditions.

1. It is necessary to determine the amount of insulated wires in the cable that you should be.

With a plug-in load, eating from a single-phase network (220V), this is either two wires (zero N and phase L), or three (zero, phase, and wire protective grounding).

With a load feeding from a three-phase network (380V), this is either four wires (three phase A, B, C, and zero N), or five (three phase, zero and protective ground wire).

The need for a protective grounding wire is determined by the design and type of connected load. All devices with an outer metal body must be ground to prevent the electric shock. When using sockets with grounding contact, a cable with a protective ground wire is required. If you use differential safety machines when connected with the load (RCO - protective shutdown devices), the protective ground wire is simply necessary for their correct operation.

2. The cross section of the conductive livers (abbreviated by CPA - in the future I will use this abbreviation) must correspond to the power of the connected load.

If the cross section is less - the wires will overheat (the smaller the cross section of the TPZ, the greater the resistance of the wire flowing electric Toku. - Consequently, at high currents on the wire, heat will be highlighted, both on the heating element). In addition to the fact that the overheating of the wire can lead to the destruction of protective insulating covers, a short circuit and the emergence of a fire, the heating wire is the loss of energy during the transmission process !!! And these losses will pay for you exactly !!!

If the cross section of CPA will be selected excessively large - first, you will spend extra money for the purchase of a cable, and secondly, difficulties may occur when connected: all devices (terminal blocks of electrical installations, devices and mechanisms, sockets, etc.) are designed for Specific power and, accordingly, to a certain cross section of the connected wires. Not in every "hole" thick wire will be able to "flush"!

For correct choice required section CWA need to know the power of the connected load. According to the table of the maximum permissible load characteristics of the wires, we find the sequence of section. Maximum permissible load value for the selected section D.B. More power plug-in.

When connecting multiple loads to one cable for calculations, it is necessary to sum up their power.

Having understood with these two items, we figured out the digital part of the cable brand.

Each brand contains an alphabente part (characterizes the type and design of the cable) and the digital part (characterizes the amount of isolated CPA and the cross section). For example: WGP 3 * 2.5. This means a VG type cable in a flat design (letter "P"), contains three veins with a cross section of 2,5mm square meters.

Now let's deal with the "letters".

CPA wires and cables are made of copper or aluminum. Single insulated wire coming on sale will be labeled PV - for copper isolated housings, APB - for aluminum isolated housings.

CPA can be structurally single-wire (monashed) and a multi-breed-made from a smaller cross section, twisted together. Multi-War CCPs provide increased flexibility of wires and cables, which can be necessary when connecting various portable (mobile) devices and electrical appliances.

The flexibility class of the wire is denoted by the number, and the larger the digit - the higher the flexibility class of the wire (and more expensive).

PV1-2,5 - Copper insulated wire with single-filling residential cross section 2.5 mm?

PV3-1,5 - Copper insulated wire of an increased class of flexibility with a multi-breed residential cross section of 1.5 mm?

Immediately I note: it will be about a limited number of cable brands (VVG, AVVG, VG-NG, NG-LS VG, kg, NYM, PVS, SWVVP, SIP). Despite this, a small limited amount is confident that in 99% of cases in our "household" situations it will be enough.

Cables for VG and AVVG.

The cables of these brands are designed for laying in dry and wet rooms, for external and hidden stationary (CPA wires - monashed, the amount lived from two to five) wiring. Constructively, they are made in a flat (row laying lived under the shell - VDGP, AVVGP) and twisted (Round - VG, AVVG) versions. VG - CPA copper, AVVG - CPA from aluminum.

The insulation of cable wires and the outer shell is made of cable polyvinyl chloride (PVC) plasticists. PVC causes the temperature range ambient To operate cables from -40 ° C to +50 ° C, and installation and gasket without prior heating are possible at a temperature not lower than -15 ° C. Otherwise, it is possible to crack the protective covers and further flowing from here the trouble.

The minimum cable bending radius is 7.5 of its outer diameters.

The service life of the cable is 30 years.

The cable is allowed outdoors. However, the protective covers of the cable will be exposed to ultraviolet spectrum sunlight, and the cable service life will significantly reduce - the shell, and then insulation "crack up". The most resistant to the effects of the ultraviolet cable of black, as ultraviolet rays will immediately be absorbed by the surface and will not be able to penetrate inside the shell, causing the destruction of PVC polymer chains. That is why all cables for laying outdoors are produced black, and all regulatory documents strictly track this requirement !!!

When connecting the ends of cables, please note: the direct connection of copper lived with aluminum is unacceptable !!! The connection must be performed either bolted through the separation steel washer, or use special connecting pads, in which the copper and aluminum wires are clamped separately each fastening element. Otherwise, copper with aluminum form a galvanic pair and as a result are sharply oxidized at the point of contact. The resistance of the connection site increases, heating occurs, possibly melting insulation of wires, their short circuit and trouble are provided !!!

The release of cables of the VG and AVVG has long been mastered by industry. The cables were very widespread, and it should be noted that the cost of these cable brands is lower than others with a similar design.

Cables VG NG, NG-LS VG.

VG NG is cable VVG.which, as defensive covers, PVC plastic, not supporting burning. And notice - it is unsupported! Being in the area of \u200b\u200bopen fire, plastic is burning, but when the flame is terminated, it fades. Thus, the possibility of disseminating a fire during electrical wiring is prevented (if during the closure, other items should not be loaded until the voltage shut off systems are triggered).

The NG-LS UG, in addition to this, contains in insulating covering additives that prevent the active release of suffocating smoke (including the resulting chlorine - after all, polyvinyl chloride) during thermal decomposition. This is relevant when the fire occurs: people die when they cannot leave the zone of fire from suffocation !!!

For this public use and possible large accumulation of people, it is necessary to use cables and wires in the execution of NG-Ls (which the projects of modern structures are required).

The plastic with the properties described is more expensive and this, of course, is reflected at the cost of the cable.

Cables kg.

Abbreviation kg decoded as a flexible cable. CB Cable - copper multi-boosters. The amount lived from two to five. Insulation and shell veins are performed from rubber based on isoprene and butadiene rubber.

The cable is designed to attach mobile and portable devices to electrical networks. The outer shell of the cable has an increased oil-gas resistance, and also has a light-resistance. The cable is resistant to multiple bend, and retains these properties at negative temperatures. Permits operation at ambient temperature -40 ° C? + 50 ° С.

The service life of the cable type is 4 years.

NYM cables.

This type of cable, in contrast to those discussed earlier, has an additional inner filler that fills the space between insulated cores under the shell. The filler is performed from a minor-filled vulcanized rubber, which additionally protects insulated veins from possible mechanical damage, and, sharpening when cutting, significantly facilitates the operation when connecting ends. The cable is released only in the twisted (round) version and has a practically round shape.

TPZ - Copper Monasted. Number lived from two to five

Insulating and outer coverings of cables are performed from cable PVC with increased minor compliance. This makes the cable tougher and the surface of the cable is more "slippery". It was these goals that were pursued when developing the design of this cable (the design of NYMA came from Europe) for use in modern building technologies. In addition, elevated minor filtering of cable covers ensures its reduced flammability compared to the WG. However, if the NG and NG-LS properties are required, then it is in these versions and it is necessary to acquire NYM. But for this "pleasure" of course, it will have to pay additionally.

Cable life of 30 years.

Laying outdoors without additional protection against ultraviolet exposure is invalid.

Temperature range of the Environment -30 ° C? + 50 ° C, and with negative temperatures, the cable is more prone to cracking the protective covers when bending than the VG.

This cable is much more expensive compared to the analogues of other brands and types of cables due to the more complex technology of its manufacturer and use of additional materials. However, it is very convenient in the production of large volume. mounting work. The cable is convenient exactly installers !!! The cable is easy to run in pipes, closed and curved cable channels, the cable is easy to cut and connect.

It should be borne in mind that due to the internal filler, the cable will take a larger amount in the cable channel.

All NYMA manufacturers and suppliers declare: NYM meets the highest European standards! The thing is that each manufacturer, the cable is obliged to produce it in accordance with the developed standard for this type of product. Cable and conductor products are subject to mandatory certification. This means that all cables leaving from production are obliged to be accompanied by a "certificate of conformity" and "fire safety certificate". Each supplier of cable and conducting products is obliged at the request of the buyer to present, and if necessary, and give these two certificates !!!

Now about the "height" of the European standard. The design of NYMa is such that it takes into account not only the requirements of the safe and reliable transmission of electricity, but also modern technologies Construction, when cable runs (pipes and closed curved cable channels) are immutted when the walls and floors are erected. The cable in this case is delayed in the track by a special conductor after the completion of construction and installation works. In this case, we can talk about the "height" of the standard on NYM.

In all other cases, the requirements of the European and Russian standards are identical.

Doing the wiring at the cottage I refused to use NYMA - Why should I pay extra money?! Connecting the ends of the wires is made once and with the amount of work of the time gain when using NYMA is negligible. I used the usual VVG - the insulating properties of its covers above compared to the minor plastics of NYMA. NG and NG-LS execution also did not take on what I believe that the wiring should be made competently and correctly, and not operated in extreme conditions, "as close as possible to combat" and fire conditions. Install the wiring should be so that the conditions for the emergence of the fire is excluded !!! The WDG took in a flat design, as it occupies a smaller volume and the cable channel with a lid can be lifted smaller - it looks "prettier".

Cables PVS and ShVVP.


PVS ShVVP

These cables are released only with multi-breed copper CPF with a cross section of up to 2.5 mm?.

This is due to the common and even fixed in the regulatory documents the name of these cables - the PVA is called a wire, and the ShVVP cord.

PVA can contain from 2 to 5 isolated lived, and the SVVP, as a rule, contains two veins (but may be three).

They are intended to connect various household electrical appliances operated in residential and administrative premises (refrigerators, washing machines, lamps, table lamps etc.), as well as for connecting a variety of manual power tools (drills, soldering iron, garden tool, etc.).

Insulating covers are made of cable PVC plasticists, which limits the temperature range of the environment for their operation from -25 ° C to + 50 ° C. Despite these temperatures, boldly indicated by all manufacturers, it should be noted that under the negative temperatures plastic protective covers "Dubet". Why, without prior heating at -15 ° C, it is impossible to be flexing and laying, and you can use the extension from PVA or WWNVP - because I will have to unwind it and wind up !!! Sorry, but I do not understand this !!!

For a correct choice between these two types, keep in mind that the SVVVP is flat and with a length of more than 1.5 m prone to twisting and confusing with frequent unwinding and ware. PVA round, confused less, but heavier and takes a larger volume at the same length as SVVP.

Therefore, if I need to connect a soldering iron, then I will choose the SCVVP (the soldering iron must be kept in your hand on weight and requires accurate work), and if we are talking about the electric drill, I will put the PVA length of five meters (it will not be needed to be the extension. ). Although, to be honest, I connect all your manual power to the cable KG - the wire remains flexible even in the cold and more elastic due to rubber protective covers.

Cables SIP.

Abbreviation SIP decrypt as self-supporting insulated wire.

It is designed to transmit electricity in airlines and branches to homes and economic buildings. Isolated cable veins are simply twisted and the common shell is missing. This is done for the convenience of mounting and connecting. When connected to a single-phase network, a wire twisted from two insulated conductive lives is used, and when connected to a three-phase network, from four. The most common siep with a cross section of three-term 16 mm? It is necessary to use it for branches to your homes and economic buildings.

CWP - aluminum multi-breeding veins, sculitated, as a rule, around steel carrier wire. This allows you to use less supports and suspensions when laying and abandon additional stretch marks for hanging the cable.

Housing insulation is a cross-stabilized polyethylene, resistant to the destructive effects of ultraviolet. This is achieved by introducing into an insulating material of special additives and a special effect on plastic in the manufacture of a cable. As a result, polymer material chains are stitched - additional transverse links are formed. All this in the amount of black isolation provides very high light resistance. In addition, the wires in winter does not occur on the formation of snowy growths and ice !!!

The minimum gasket temperature of the cable without heating is -20 ° C

Permissible temperature mode operation from -50 ° C to +50 ° C.

Cable life of at least 30 years !!!

For the installation of the cable, as well as for connecting to the previously paved air lines of electricity, special clamps and brackets have been developed. If you use - you don't even have to enter the cable !!! Just put the cable into special grooves and tighten the bolts on the clips. The mounting clamps are reliably fixed the cable, and the insulation plugs also pierce the insulation, providing reliable electrical contact with TPZ.

Of course, the cost of the cable corresponds to its properties, as well as the cost of special clamps and brackets. But if you need to solve the tasks that correspond to the designs of the SIP wire - costs will not be in vain when choosing exactly this wire.

And I want to add in conclusion. When choosing cables and protective devices for electricity supply, do it as correct as possible, try to get the most accurate information on your questions. All reasonable costs for your budget will turn out the savings !!! In vain spending it will be the acquisition of incorrectly selected products (and it does not matter, it is dear or cheap) !!!

Previously, only 2 types of information were transmitted on the wires: a TV signal (antenna cables) and telephone conversations (telephone cables and wires). Now information transmitted by metal wires was an order of magnitude more than even 10 years ago, which led to the appearance of a large variety of cables for transmitting information.

Antenna cables

In the image: Cable of RK 75 for television antenna, figures indicated 1 - copper lived, 2 - insulation, 3 - screen from foil, 4 - coppercraft, 5 - PVC sheath.

Now most often use such cables for television antenna: RG-6, RG-59, RG-58 or Russian version of the Republic of Kazakhstan 75. These are coaxial cables that are well transmitting high-frequency signals for the TV and radio. Such a cable consists of central copper veins with a cross section of 1 mm 2, surrounding it isolation from foamed polyethylene, an aluminum foil screen, an external conductor from a coppercraft and a protective shell of PVC.

RG brand cable have many varieties that are distinguished by some technical characteristics.

Computer cables (twisted pair)

In the image: Cable for building computer networks with twisted pairs.


The cable consists of one or more pairs of wires, passing pairs, thanks to which the signal transmission is improved. Each conductor is enclosed in PVC insulation. The cable can be enclosed in a moistureproof shell. In the design of the twisted pair there is a discontinuous thread, thanks to which it is easier to get to the metal lived. There are several types of cables for computer networks:

UTF unprotected, without a common screen for pairs of wires;

FTP. with an aluminum foil screen;

STP. With a common screen made of copper grid and each twisted pair is protected by its screen;

S / FTP. With a shared foil screen and each pair is enclosed.

In cables for computer networks there can be a different number of twisted pairs. The most common cable for these goals SAT5E, which consists of 4 pairs of wires of different color.

Telephone cables and wires

There are 2 main types of telephone cables:

1. Used for laying line to the building;

2. Used to connect subscribers inside the building.

TPPEP The most frequently used cable to connect a large number of subscribers. The cable consists of wiring in pairwise. Housings made of soft copper wire with a cross section of 0.4 or 0.5 mm 2 coated with polyethylene insulation. Outer shell from the same material or vinyl.

If necessary, the varieties of cable are used or in which the internal space is filled with a hydrophobic seal. Cable CTP can be laid almost in any conditions, under the ground, in cable channels or by air.

In the image: Two-core telephone wire TRV.


TRV One or milled telephone wire for laying indoors. This is a flat wire with separated copper single-robes with a cross section of 0.4 and 0.5 mm 2. Insulation from PVC. The wire can be used at temperatures from -10 to +40 ° C, the humidity should not exceed 80% at a temperature of 30 ° C.

TRP According to the characteristics, it looks like a TRV, but is made with polyethylene insulation, so that it is better to transfer the environmental impact and it can be laid outside of buildings.

PCLP Cord for telephone wires of high flexibility with multi-breeding veins. Isolation lived from polyethylene, which are covered with a shell from PVC from above. The amount of 2 or 4 lived, the cross section is from 0.08 to 0.12 mm 2. It is used to hold indoor lines and in telephone sets.

PRPPM Flat wire with copper single-robes with insulation and polyethylene sheath. There is a wire with a PVC sheath. Number 2, section 0.9 or 1.2 mm 2. Used for laying telephone lines outdoors, on air supports, in the ground and walls of buildings. Temperature range for Operation -60 to +60 ° C.

Special types of electrical cables and wires

If planned to operate electricity of the net In conditions of strongly different from normal, special cables and wires must be used.

RKGM Power mounting single-core flexible thermal resistance wire. Copper lived, multi-breeding, cross section 0.75 - 120 mm 2. Cutonic rubber insulation, fiberglass sheath, impregnated with heat-resistant enamel or varnish.

The RCMM wire is designed for rated voltage up to 660 V and frequency up to 400 Hz. Resistant to vibration high humidity (up to 100% at a temperature of + 35 ° C), thermosetics (range of operating temperatures -60 to + 180 ° C). The wire is protected from malicious effects of varnishes, solvents and fungal mold. The perfect conductor for rooms with elevated temperature (boiler rooms) is suitable for wiring in baths, saunas, connecting wind wardrobes.

PNSV Heating single-core wire, served single-robust from venelenny or galvanized steel. The cross section of the vein - 1.2; 1.4; 2 and 3 mm 2. Insulation from PVC or polyethylene. Rated voltage up to 380 V, frequency - 50 Hz. The wire can be operated in the temperature range of -50 to + 80 ° C, it is not afraid of alkalis, it can be immersed in water. Used as a heating element, warm floors are made from PNSV.

Runway Single-core copper wire. There lived a multi-breed, enclosed with polyethylene, shell also from polyethylene or PVC. The cross section of the vein is 1.2 - 25 mm 2. Rated voltage 380 or 660 V, frequency 50 Hz. The wire is resistant to pressure change. Range of operating temperatures -40 to + 80 ° C. Most often used for artesian wells, immersed in water under high pressure.

LED cable It consists of conductive veins along which additional wires are placed with successively connected LEDs of different colors. Diodes are usually located at a distance of 2 cm. Such a cable can be used to create luminous solutions of a home or stage interior.

There are still electroluminescent wires that are similar to LED cables. With the help of such wires, you can create glowing inscriptions, it is a more convenient alternative to neon tubes, as the cable is cheaper and unlimited by length.

Many private builder make electric wiring In homes and apartments on their own. Wire selection - a dilemma that occurs almost immediately to make right choice It is necessary to explore the basic properties of electrical wires used in everyday life.

Cable products or cable-conductive products are usually called any kind of uninsulated or insulated conductors, primarily intended for transmitting electrical energy or information, as in computer networks.

Conductive and cable products include insulated and uninsulated cords, ribbons, wires, optical cables with lightweight fibers, tires, cables with metal conductive conductors.

Cord - these are several isolated flexible or particularly flexible sections of up to 1.5 mm, laid parallel or can be twisted, on top of which, again, depending on the operating conditions, a non-metallic shell can be applied and protective

The wire - These are isolated veins or even one uninsulated, on top of which, depending on the conditions of gasket and operation, there may be a non-metallic shell, winding or braid with fibrous materials or wire.

Cable - One or more isolated veins (conductors) enclosed in a non-metallic shell or metal, on top of which, depending on the conditions of gasket and operation, protective cover can be superimposed into which armor can enter.

By type of insulation of power cables distinguishes:

  • power cables with plastic isolation;
  • power cables with paper insulation, including oil-filled and impregnated;
  • power cables with rubber insulation, etc.

Predncable Aznament and Classification

Cables, depending on the material of the transmitted energy conductive, cores or information are divided into two groups:

  1. Cables with optical fibers.
  2. Cables with metal veins electric.

Optical cables most often have additional metal conductive conductors. Electrical metal cables are classified by the type of isolation, the magnitude of the voltage, purpose and in many other features.

The magnitude of the linear operating voltage power cables are divided into:

  • cables on voltage 1..10 kV;
  • cables on voltage 110 .. 500 kV;
  • cables for voltage up to 1 kV;
  • cables on voltage 20 ... 35 square.

The most important element in all types of cords, wires, cables, is the screen, conductive lived, exterior covers and shells.

Uninsulated isolation wires do not have. Depending on the purpose and operating conditions of the wires and cables, the outer covers, the screen may be absent.

Conductive veins are manufactured either from aluminum or copper. In the last decade, cable manufacturers are based on manufacturing - copper. Aluminum cores are denoted by the letter A. Veins are sectoral (shaped), round, and shaped, infertable.
