Abstract

The invention discloses a rubber cover power cable utilized in a high flexibility bad environment. The rubber cover power cable comprises cable cores, and each cable core is twisted by multiple rubbercover insulating line cores; the gaps of the cable cores are filled with vulcanized rubber filling bodies, silicone rubber internal sheaths are arranged outside the vulcanized rubber filling bodies,the silicone rubber internal sheaths are wound by copper wire shielding layers, the copper wire shielding layers are extruded by polyethylene insulating layers, the polyethylene insulating layers arewound by heat-resistance ethylene-propylene rubber, and the heat resistant ethylene-propylene rubber is weaved by steel belt armored layers, finally, the outermost layer of the cable is extruded by anethylene propylene diene monomer outer sheath, and the ethylene propylene diene monomer outer sheath is covered with a silica gel pipe. The rubber cover power cable has very high heat resistance, cold resistance, weather resistance, electrical conductivity, thermal conductivity, radiation resistance, high flame resistance and breathability and is applicable to a bad environment.

Description

Technical field [0001] The invention relates to the field of cables, in particular to a rubber-sheathed power cable used in a highly flexible and harsh environment. Background technique [0002] At present, the conductors of power cables are mostly rigid structures with poor flexibility. The insulation and sheath are made of cross-linked polyethylene and polyvinyl chloride materials. They are prone to ageing when used under acidic, alkaline, oily, low temperature and other environmental conditions, resulting in a long service life of the cable. At present, the country vigorously promotes environmental protection and energy saving projects, which has broad market prospects. The main factor that determines the service life of cables is the aging of non-metallic materials in the cable structure. Changing the aging performance of non-metallic materials in the cable structure is to meet the development of long-term safe operation of cables. trend; [0003] Rubber products are prone to ...
