CROSSLINKED POLYETHYLENE INSULATED HALOGEN-FREE LOW-SMOKE FLAME-RETARDANT SPECIAL CONTROL CABLE

摘要

Disclosed in the present utility model is a crosslinked polyethylene insulated halogen-free low-smoke flame-retardant special control cable in the technical field of control cables, the cable comprising an aluminum inner lining pipe; a cable core is provided between two adjacent sets of heat conductive members; the cable core comprises a conductor disposed between the two adjacent sets of heat conductive members; heat dissipating members of the same structure are provided on the outer walls of multiple sets of heat conductive members; a flame-retardant inner sheath wraps the outer wall of an oxygen barrier layer; a flame-retardant layer wraps the outer wall of a tensile-resistant layer; and a crosslinked polyethylene insulated sheath is provided at the outer wall of the flame-retardant layer. The present utility model is provided with heat conductive members and an aluminum inner lining pipe, which facilitates the leading out of a cable core; in addition, heat dissipation is achieved by means of heat dissipating members dissipating heat outwards, which can quicken the transfer of heat at the inner part of the cable, thus increasing the heat dissipation rate of the cable, and ensuring the working efficiency and working quality of the cable.
