- CABLE CONSTRUCTION
- Conductor: The conductors shall be solid, annealed and bare copper with a diameter of AWG23 and minimum acceptable diameter shall be 0.546mm.
Insulation: Each conductor shall be insulated with solid high density polyethylene. The Insulation shall be uniform and shall not have any defects. The diameter over the insulation shall be maximum 1.22mm.
Sheath: The flame retardant PVC or LSZH(Low Smoke Zero Halogen) compound colored grey
or other colors shall be applied over the cable core.
