Designed for use on earthing circuits within the ship wiring and marine industry 657 SW4 earthing cables are manufactured to BS 6883 and are double insulated for electrical safety.
The outer sheath is colored green/yellow for identification.
It is the current carrying component of the cable.
Stranded, high conductivity plain annealed copper wires as per class 2 in BS 60228 and IEC 60228
Aluminium, stranded, compacted conductors
The rated voltage level of the cable depends on the dielectric strength and thickness of the insulation
The insulation of standard wiring cables is PVC grade Type TI 1 of BS 7655 (formerly BS 6746) suitable for a maximum continuous conductor operating temperature of 70˚C.
-5°C to +70°C
