Abstract

The utility model discloses a power cable used for a ship. The cable comprises an aluminum conductor, a teflon sheath layer, a silicone rubber insulating layer, a wrapping tape layer, an aluminum strip shielding layer, a copper strip shielding layer, a low smoke zero halogen polyolefin sheath layer and a butyronitrile insulating layer. One teflon sheath layer wraps the aluminum conductor. One silicone rubber insulating layer wraps the teflon sheath layer. One wrapping tape layer wraps the silicone rubber insulating layer. One aluminum strip shielding layer wraps the wrapping tape layer. One copper strip shielding layer wraps the aluminum strip shielding layer. One low smoke zero halogen polyolefin sheath layer wraps the copper strip shielding layer. The cable of the utility model is especially suitable for the fields of ships, aviation and the like. The cable possesses the characteristics that an electrical property is superior; acid and alkali resistance performance is good; tearing resistance performance is good; antimagnetic interference performance is achieved; heat oil resistance and fire resistance performance is achieved. The cable can maintain good electrical performance and mechanical performance in a severe environment.
