PGVZ
To protect against mechanical damage and corrosion, an insulating layer of transparent polyvinyl chloride plastic or polyurethane is applied to the conductive cores of the products. The electrical resistance of the cores to direct current per 1000 m of length and a temperature of 20 degrees corresponds to GOST 22483 - 77 .
The wires are resistant to the effects of elevated operating temperatures of the environment: 50°C for PGVz type wires and up to 80°C for PGUz type wires;
The wires are resistant to low operating temperatures: up to - 40°C for PGVz wires and up to - 60°C for PGUz wires.
PGVz - grounding cable , with a core made of copper wires, flexible, with polyvinyl chloride insulation;
PGUz - grounding wire, flexible, with a core based on copper wires in polyurethane insulation.
Class 6 conductors are divided into 2 subclasses according to their degree of flexibility:
- 6A – flexible core;
- 6B - highly flexible core.
