Note: Asterisk ** denotes that the standard compliance is optional, depending on the oxygen index of the PVC compound and the cable design.
CABLE CONSTRUCTION
| Conductors |
Copper clad steel or bare copper, solid according to IEC 60228 class 1 |
| Insulation |
PE compound |
| Overall Screen |
Plain copper wire braid |
| Inner Sheath |
Thermoplastic PVC compound |
| Armouring |
CWB : Copper Wire Braid
SWB : Steel Wire Braid
SWA : Steel Wire Armour |
| 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 |
