Abstract
The utility model discloses a heat-resistant fireproof flexible cable composed of aluminum cable cores, an insulating layer, a chlorosulfonated polyethylene sheath layer, a tinned aluminum wire braiding armor layer and an outer sheath layer. Three aluminum cable cores are wrapped in the insulating layer in an extruding manner, the insulating layer is wrapped with the chlorosulfonated polyethylene sheath layer, and the chlorosulfonated polyethylene sheath layer is wrapped with the tinned aluminum wire braiding armor layer. The heat-resistant fireproof flexible cable is widely applied in the fields such as metallurgy, ship, aviation and chemical petroleum and the like, is provided with excellent shielding and insulating performance and excellent heat-resistant fireproof performance, and is also advantaged by aging resistance, acid and alkali resistance, corrosion resistance, and high pull resistance.
