Abstract
The utility model discloses a compound insulated high-temperature resistant power cable. Conductors are copper wires made by drawing oxygen-free copper rods. A fluorinated ethylene propylene insulating layer is extruded on each conductor. A polyvinyl chloride insulating material composite layer is arranged outside each insulating layer. A filling rope is arranged among and twisted with multiple insulating wire cores to form a cable core. The cable core is sequentially provided with, from inside to outside, a wrapping layer and a low-smoke zero-halogen flame-retardant polyolefin sheath layer. The compound insulated high-temperature resistant power cable is simultaneously excellent in heat-resistant property, low temperature-resistant property, flame-retardant property, electrical-insulating property, water-resistant property as well as moisture-resistant property. The flame-retardant oxygen index of the compound insulated high-temperature resistant power cable is as high as 90.
