Fire-Resistant Control Cables with Polymer Insulation for Reliable Performance

1. Conducting core - single-wire round, 1 class according to GOST 22483 made of soft copper wire with nominal cross-section from 1,0 to 6,0 mm2.
2. thermal barrier - winding of two mica-containing tapes with overlap of not less than 40%.
3. core insulation - of halogen-free polymer composition.
4. Core - insulated cable cores twisted by twisting.
5. Inner sheath - of halogen-free polymer composition with filling of gaps between cores.
6. shield - in the form of a wrapping of copper tape with nominal thickness of 0,06 mm with an overlap ensuring the continuity of the shield.
7. Sheath - of halogen-free polymer composition.

Cables are designed for transmission and distribution of electrical energy and electrical signals in stationary electrical installations at alternating voltage up to 0,66 kV with frequency up to 100 Hz. Cables are intended for cable lines of power supply of equipment of safety systems of AC, wiring circuits of fire systems....
