Industrial Cables Multi-Core Flexible Cables

6241B/6242B/ 6243B to BS 7211

Application and Description

6241B/6242B/ 6243B to BS 7211 cables are suitable for fixed installation particularly for situations in which low emission smoke and domestic wiring cable for the surface wiring of sockets and lighting where fire, smoke emission and toxic fumes create a potential threat to life and equipment. Can be installed in fixed installations in dry or damp premises on walls, boards or trays, in channels or embedded in plaster. Suitable for laying in conduit or trunking where mechanical protection is required.

Cable Construction

Fine bare copper strands
Stranding to IEC 60228 Class 1 or 2
Thermosetting core insulation type EI5 or GP 8
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
LSOH sheath, type LTS 2, white
