British Standard Industrial Cables
680TQ to BS 6007

Application and Description

These 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 CL-5 or IEC 60228 CL-5
  - EPR 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

Core Identification

• 2 cores: Brown, Blue
  3 cores: Green/Yellow, Brown, Blue
  4 cores: Green/Yellow, Brown, Black, Grey
  5 cores: Green/Yellow, Blue, Brown, Black, Grey
  6 cores and above: white insulation with black numerals

Technical Characteristics

• - Working voltage: 450/750 volts
  - Minimum bending radius: 8.0xOverall diameter (below 25mm²)
  10xOverall diameter (above 25mm²)
  - Temperature Range: -20º C to +85º C
  - Flame retardant: IEC 60332.1
  - Insulation resistance: 20 MΩxkm
