The power cable VVG is designed to transmit and distribute electrical energy when it is stationary connected to a voltage of up to 1,000 V AC at 50 Hz. It can be laid in dry and wet industrial premises, on cable racks, in blocks, in the open air. Not recommended for laying in the ground.
VVG, VVGng, VVGngd are power cables with copper conductors, PVC insulation and sheath.
They are designed for the transmission and distribution of electrical energy in stationary installations for a rated alternating voltage of 660 V and 1000 V with a frequency of 50 Hz.
They are used when laying in blocks, on specialized cable tray systems, can be used in industrial premises, distribution and lighting devices, as well as in ordinary residential premises as electrical wiring.
Special protection is needed for the laying in the ground.
Applicability scope
It is used for laying in blocks, on specialized cable tray systems, in industrial premises and those with high corrosive activity. It is also used for the distribution and lighting devices, as well as for outdoor installation. VVG cable is especially popular in laying of electrical wiring in ordinary residential buildings and administrative institutions. The copper conductors are more ductile than aluminum ones, they do not break due to frequent bends, the contacts are more reliable, and the electrical conductivity is higher. Due to this, copper wire can withstand higher loads than aluminum one with the same cross-section. VVG cable has an extremely wide range of applications, and only due to the lack of armor it is not advisable to lay it in the ground. If necessary, the laying in the ground is possible with the use of special protection.
The high quality and a wide range of label sizes of this cable brand lead to its high demand.
There are versions of this cable – VVGng and VVGngd. The «ng» index means that the cable is flame-retardant while «ngd» indicates that the cable sheath is made of non-combustible PVC with reduced emission of toxic substances. This is especially important in the areas with a high risk of fire, in dry environments and high temperatures. VVGng is often used in wooden buildings, gypsum board structures, floating ceilings, bathrooms, bath houses and saunas. VVGngd is popular for the laying in apartments and houses, cinemas, shopping centers and other public places, at transformer substations, switchboards and other facilities with increased fire safety requirements.
