  • Fire resistive cable system
    Patent number: 11276511
    Abstract: A fire-resistive cable system comprises an electrical cable housed in a fiberglass-reinforced thermosetting resin conduit. The electrical cable comprises a conductor and has only one couple of mica tapes surrounding the conductor. The couple of mica tapes are formed of a first mica tape and a second mica tape wound around the first mica tape. The mica layer of the first mica tape faces and contacts the mica layer of the second mica tape. The fiberglass-reinforced thermosetting resin conduit is made of a material comprising fibers of a glass selected from E-glass and E-CR-glass, and a resin.
