Abstract

The utility model discloses a polyvinyl chloride insulating polyethylene inner sleeve bare wire braided armored control cable. The polyvinyl chloride insulating polyethylene inner sleeve bare wire braided armored control cable comprises a main conductor, control conductors and a quadrilateral star-shaped silica gel skeleton, and a silicone rubber insulating layer, a butyronitrile polyvinyl chloride insulating layer and a copper aluminum strip composite belt lapping shielding layer are wrapped on the outside of each of the main conductor and the control conductors separately and orderly. The main controller is placed in the center of the quadrilateral star-shaped silica gel skeleton, the control conductors are placed in the obtuse angle gaps outside the quadrilateral star-shaped silica gel skeleton respectively, and a finer wire braided fireproof layer, a glass fiber braided layer, a PTFE lapping layer and an outer sheath are wrapped on the outside of the quadrilateral star-shaped silica gel skeleton orderly. The polyvinyl chloride insulating polyethylene inner sleeve bare wire braided armored control cable of the utility model uses the quadrilateral star-shaped silica gel skeleton, and the control conductors are placed in the obtuse angle gaps outside the quadrilateral star-shaped silica gel skeleton respectively, so that the polyvinyl chloride insulating polyethylene inner sleeve bare wire braided armored control cable is novel and reasonable in structure, good in shielding and fireproof performances and long in service life, and is economic and practical.
