Abstract (en)

[origin: EP0125747A2] An electrical conducting wire (11), capable of withstanding high continuous operating temperatures without emitting smoke or halogens and without supporting flame, includes a conductive core (20) of nickel, or copper or iron plated with tin, nickel or silver and surrounded by a plurality of successive insulating layers (30, 40) of polyimide film strip or tape (31, 41). The first of such layers (30) is formed by helically winding the tape of polyimide film about the core with adjacent edges overlapping. Each successive layer (10) is helically wound in the opposite direction and surrounding the next inner layer. A braided fiberglass jacket (50) encases the core (20) and the insulating polyimide film layers (30, 40).
