- CABLE CONSTRUCTION
- Conductor: The conductors shall be solid, annealed and bare copper with a diameter of AWG26
Insulation: Each conductor shall be insulated with solid high density polyethylene. The insulation shall be uniform and shall not have any defects.
Sheath: The flame retardant PVC or LSZH(Low Smoke Zero Halogen) compound colored grey or other colors shall be applied over the cable core.
