Firetuf FT L-SIFER
London Underground Fire Resistant Single Core Cable
Firetuf FT L-Sifer is a fire resistant, zero halogen and low smoke (OHLS®) single core cable designed to maintain circuit integrity during a fire and is approved by LUL for above and below ground use.
L-Sifer is ideally suited to drawing into conduit installations that provide adequate mechanical protection and it forms the key part of a wiring system for evacuation and fire fighting applications.
