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: 14AWG solid bare copper.
Insulation: Low density PE compound.
Screen1: Aluminium/polyester or aluminium tape.
Screen2: Tinned copper braid.
Inner Sheath: Low smoke and halogen-free polyolefin, coloured black.
Armour:
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.
Physical And Thermal Properties
