Abstract

The utility model discloses a ship drag chain cable mainly comprising tin-coated copper conductors, a semiconductor shielding layer, an insulating layer, an inner sheath layer and an outer sheath layer. Twelve tin-coated copper conductors are stranded to be an integral body and then wrapped with the semiconductor shielding layer, the semiconductor shielding layer is wrapped with the insulating layer, the insulating layer is wrapped with the inner and outer sheath layers, the insulating layer is prepared from polyperfluoro ethylene-propylene insulating materials, and the inner sheath layer is prepared from low smoke zero halogen polyolefin sheath materials. The ship drag chain cable has the characteristics of high aging resistance, oxidation resistance, and acid and alkali corrosivity resistance, and the ship drag chain cable is excellent in shielding property and high in pull resistance, and can be widely used in fields, such as ship manufacture, power plant and petroleum chemical industry, with high environment temperature and severe conditions.
