6241Y/6242Y/ 6243Y to BS 6004

Application and Description

6241Y/6242Y/ 6243Y to BS 6004 cables are suitable for fixed installation in dry or damp premises on walls, boards or trays, in channels or embedded in plaster. They should be laid in conduit or trunking where mechanical protection is required.

Cable Construction

 

• Fine bare copper strands

  Stranding to IEC 60228 CL-1 or 2

  PVC insulation type TI1 to BS 7655

  The core or cores shall be laid parallel with the uninsulated circuit protective conductor

  For twin cores, the protective conductor centrally placed between cores in same plane

  For 3 cores, the protective conductor centrally placed between black and grey cores in same plane

  PVC sheath type T6 to BS 7655

Core Identification

• 2 cores: brown and blue, or, for 2 × 1.0 and 2 × 1.5 cables, brown and brown

• 3 cores: brown, black (centre core) and grey

Technical Characteristics

• Working voltage: 300/500v

  Test voltage: 2000 volts

  Minimum bending radius: 4xOverall diameter

  Flexing temperature: -15º C to +70º C

  Short circuit temperature: +160º C

  Flame retardant: IEC 60332.1

  Insulation resistance: 10 MΩxkm
