The core is enclosed with a jacket (28)which also is made of a non-halogenated plastic material. The non-halogenated plastic material of the insulation is selected from the group consisting of a polyetherimide and a silicone-polyimide copolymer, or a blend comprising the polyetherimide and the silicone-polyimide copolymer. For the jacket, the plasticmaterial includes a blend composition of silicone-polyimide copolymer and a flame retardant and smoke suppressant system comprising titanium dioxide and zinc borate.
