VOLTAGE RATING
450/750V
CABLE CONSTRUCTION
Conductor: Plain annealed copper wire, stranded according to IEC(EN) 60228 class 2.
Insulation: Extruded cross-linked XLPE compound.
Filler, binder (if any): PP, PET, PVC
Overall Screen: Copper tape
Outer Sheath: Thermoplastic PVC compound. UV resistance, hydrocarbon resistance, oil resistance, anti rodent and anti termite properties can be offered as option. Compliance to fire performance standard (IEC 60332-1, IEC 60332-3, UL 1581, UL 1666 etc) depends on the oxygen index of the PVC compound and the overall cable design. LSPVC can also be provided upon request.
