Abstract
1500121 Fire resistant cable PIRELLI GENERAL CABLE WORKS Ltd 8 Dec 1976 [9 Jan 1976] 00825/76 Heading H1A A multi-core cable, e.g. a telephone cable, for resisting high temperatures comprises silicone rubber insulated conductors, a bare earth wire, a sheath consisting of a laminate of a thermoplastic polymeric composition/aluminium or copper foil and an extruded sheathing of a fire retardant polymeric composition around the laminate, the metal layer being on the inside of the laminate and contacting the earth wire throughout the length of the cable. The polymer for the laminate and the outer sheathing may be P.V.C., polyvinylidene chloride, polyethylene or polypropylene. In the case of the outer sheathing it may alternatively be a thermoplastic rubber and be mixed with a fire retardant, e.g. chlorinated paraffin, antimony trioxide, magnesium carbonate, zinc borate or aluminium hydrate. The earth wire(s) may be tinned copper laid helically or straight.
