Cable Construction

Twin & Earth Cables 300/500V Twin & Earth Cables (2-3 Cores)
Conductor Annealed copper conductor,class 1 (1.0mm² to 2.5mm²) or class 2 (4mm² to 35mm²) according to BS EN 60228.
Insulation PVC Type TI 1 according to BS EN 50363-3.
Circuit Protective Conductor (CPC) Annealed plain copper (class 1 or 2)
Position of CPC Centrally placed between cores in same plane (twin); centrally placed between black and grey cores in same plane(3-core).
Outer Sheath PVC Type 6 according to BS 7655-4.2.
Outer Sheath Option 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.
