1. Conducting core - single-wire round, 1 class according to GOST 22483 from soft copper (nominal cross-section from 0,75 to 6,00 mm2) wire.
2. insulation of cores is made of polyvinylchloride plasticate.
3. Core - insulated cable cores twisted by twisting.
4. Separating layer (sheath) - made of polyvinylchloride plastic of reduced flammability with filling of gaps between cores.
5. Protective cover of BbShv type:
- armour made of two steel galvanised strips 0.3 mm thick,
- protective hose made of polyvinylchloride plasticate of reduced flammability.
Cables are designed for transmission and distribution of electrical energy and electrical signals in stationary electrical installations that require cable sealing at entry, at AC voltage up to 660 V with frequency up to 100 Hz or DC voltage up to 1000 V. .
