Applying area and purpose
Cables are designed for fixed connection to electric devices, apparatuses, terminal assemblies of electrical switchgears with rated alternating voltage up to 660 in frequencies up to 100 Hz or constant voltage up to 1000 V.
Kvvg cable is used for laying in rooms, channels, tunnels, in aggressive environments, in the absence of mechanical stress on the cable.
Kvvge cable is used for laying in rooms, channels, tunnels in the absence of mechanical influences on the cable, in an aggressive environment and the need to protect electrical circuits from the influence of external electric fields.
A cable of the kvbshv brand is used for laying in rooms, channels, tunnels in aggressive environments and in places exposed to stray currents, if the cable was not subjected to significant tensile forces.
The KVVGZ cable is used for electrical installations that require cable glands during entry.
Fire hazard class according to NATIONAL QUALITY STANDARD 31565 o1.8.2.5.4.
