  • Fire resistant fiber optic cable
    Patent number: 4653851
    Abstract: A fiber optic cable includes layers and elements for mechanical and fire protection of the cable, all having the same or substantially the same thermal coefficient of expansion as the optical fibers. The fiber optic cable core is protected against flames by at least two layers of mica separated by a layer of synthetic material.
    Type: Grant

  • Fire and oil resistant cable
    Patent number: 4547626
    Abstract: A cable is described which has improved flame/fire and oil/abrasion resistant properties. The cable is halogen free since the conductor insulation and all sheaths are of the self-extinguishing type. A metal screen braided at an angle between 35.degree. and 45.degree. formed between the individual wires and a plane at right angles to the cable axis over a vulcanized filler sheath provides protection of the cable conductors during fires. Outermost there is placed a thin oil and abrasion resistant extruded layer of nylon.

  • Method for making electrical cables
    Patent number: 4518445
    Abstract: This invention relates to continuous manufacturing of insulated wire and conductor, and in particular to heating cables having "cold ends". A process is described by which predetermined lengths of resistance conductor (4) and of cold end conductor (9) are continuously and alternatively jointed together. After insulation and provision of additional protective sheats the continuous composite conductor is cut into cold end heating cables. A conductor jointing process is described.
