Few people think about the features of cable products when laying

wiring in their homes. But for the safety of everyone inside the building, it is necessary to correctly and carefully select parameters such as the number of cores and the cross section. And these indicators are not limited. This is especially true for products such as VVG cables. Their technical characteristics may surprise any user.

VVG power cable - what is it?

In its structure, any VVG power cable contains copper conductors. They are used to transmit electrical energy. The rated voltage of this cable can be 1.0KW and 0.66KW. VVG cables, the technical characteristics of which may be different, are often used in industrial and domestic buildings, in various areas of life.

VVG cables are often used when laying a home electrical network, when connecting street lighting and household electrical appliances. Manufacturers recommend laying at a temperature of about minus fifteen degrees. In addition, care must be taken to usePVC pipes or special cable channels if the VVG cable is laid in the ground. This is necessary to protect against mechanical damage.

What is the use of this cable?

VVG cables, whose technical characteristics are determined quite simply, are considered the most profitable and safe solution for many systems in modern buildings. Compared to conventional wires, cable protection always has superior performance. In almost every house under construction, wiring is now being laid using VVG cables. Even small sections of cable are enough to work with large areas. In the passport data, you can see what power of the device is best suited in a particular case.

VVG cable and its structure

Inside any VVG cable there can be four, two or three copper cores. In addition, neutral conductors or grounding conductors are often used. VVG cables, the technical characteristics of which depend on different parameters, are painted in different colors even at the production stage in order to make it easier to understand where and what to connect.

For example, blue or blue color indicates a zero core. Grounding is indicated in yellow-green. This must be taken into account in order to lay the wiring without any problems.

Some features of the VVG cable

Most often, VVG cables are used for outdoor installation, for this they are protected by very high quality insulation. The characteristics of the VVG cable also contribute to this application.

Such cables are designed to work in networks where the voltage does not exceed 35 kW. The cores are made of soft copper wire, they themselves have a round shape. If the cross section of the core exceeds 16 square millimeters, then it has a multi-wire design.

In general, a three-core design can also be used if the cross section exceeds 25 square millimeters.

The core is the main element in such a design as the VVG copper power cable. It is also made from a core, but it is isolated from all the others, special materials are used for production. In addition, you can find cables where there are five, four, three or two cores twisted together in the core at once.

Neull core version is available for stranded cables.
