6241B/6242B/ 6243B, LSOH Flat Wiring Cables with circuit protective conductor
Application and Description :
These 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
Strands to IEC 60228 Cl-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
Insulation Colour :
Single core: brown or blue Twin: brown and blue, or, for 2 × 1.0 and 2 × 1.5 cables, brown and brown 3-core: brown, black (centre core) and grey
