Applying area and purpose
Cables are designed for fixed connection to electrical appliances, devices, terminal assemblies of electrical switchgears for rated alternating voltage up to 660 at a frequency of up to 100 Hz or direct voltage up to 1000 V, for laying in rooms, channels, tunnels, in aggressive environments, in the absence of mechanical stress on the cable. Laying in the ground (trenches) is allowed while protecting the cables at the points of exit to the surface.
Cables are used for laying in cable structures and premises to ensure fire safety of cable chains during group laying.
Cables kvvgzng (a) are used for electrical installations requiring compaction during entry.
Fire hazard class according to NATIONAL QUALITY STANDARD 31565 p1b.8.2.5.4.
