Industrial Cables Multi-Core Flexible Cables

680TQ to BS 6007

Application and Description

680TQ to BS 6007 cables are designed for temporary building sites as extension leads for portable or fixed equipment. The copper braid prevents earth leakage and offers mechanical protection.

Cable Construction

Fine bare copper strands
Stranding to BS 6360 Class 5 or IEC 60228 Class 5
EPR-HOFR( Ethylene Propylene Rubber-Heat and Oil Resistant and Flame Retardant) insulation
CSP(Chlorosulphonated Polyethylene), HOFR (Heat and Oil Resistant and Flame Retardant) bedding
TCWB(tinned copper wire braid)
CSP(Chlorosulphonated Polyethylene), HOFR (Heat and Oil Resistant and Flame Retardant) sheath

680TQ to BS 6007
