British Standard Industrial Cables
657TQ to BS 6883

Application and Description

These cables are designed for use in offshore applications where mechanical protection is not required. Examples of application include fixed wiring in ships and fixed offshore drilling rigs and oil platforms.

Cable Construction

  - Stranding to BS 6360 CL-2 or IEC 60228 CL-2
  - EPR(Ethylene Propylene Rubber) rubber insulation to BS 7655
  - LSOH(Low Smoke Zero Halogen), type SW4 to BS 7655

Core Identification

• 1 core: Black or red
  2 core: Black, red
  3 core: Red, yellow, blue
  4 core: Red, yellow, blue, black
  5 cores and above: white insulation with black numerals
