Few people think about the features of cable products, laying
wiring in their homes. But for the safety of all who are inside the building, it is necessary to correctly and carefully select parameters such as number of cores and section. And these indicators are not limited to. This is especially true for products such as VVG cables. 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 transfer electrical energy. The rated voltage of this cable can be 1.0 kW and 0.66 kW. VVG cables, the technical characteristics of which can be different, are often used in industrial and domestic buildings, in different spheres of life.
VVG cables are often used when laying a home electrical network, when connecting street lighting and home appliances. Manufacturers recommend laying at a temperature of about minus fifteen degrees. In addition, care must be taken to use PVC pipes or special cable channels if the VVG cable is laid in the ground. This is necessary to protect against mechanical damage.
What benefits does this cable bring?
VVG cables
, the technical characteristics of which 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 better characteristics. In almost every house under construction, wiring is now 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 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 conductors. In addition, zero or ground 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 needs to be connected.
For example, cyan or blue indicates a zero core. Grounding is indicated in yellow-green. This must be considered in order to lay wiring without any problems.
Some features of 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 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 vein, but it is isolated from all the others; special materials are used for production. In addition, you can find cables where five, four, three or two conductors are twisted together in the core at once.
Version with zero core is provided for multicore cables.
