The invention relates to a downhole flame-retardant power cable. The downhole flame-retardant power cable comprises three insulation cable cores, each insulation cable core is composed of a conductor and an insulation layer outside the conductor, the insulation cable cores are pressed and wrapped by a wrapping tape, and a metal armor layer and a sheath are sequentially wrapped outside each cable core. The downhole flame-retardant power cable is simple in structure, low in arrangement requirements and production cost, low-smoke and flame retardant.
Description
technical field [0001] The invention relates to a cable, in particular to an underground flame-retardant power cable. Background technique [0002] With the rapid development of my country's industry, the scope and amount of cables used in the industry are increasing. The flame retardancy of ordinary insulated cables is poor. After adding flame retardants, the electrical insulation will be reduced, and a large amount of toxic and harmful smoke will be produced during combustion, which is harmful to the environment. , equipment and personnel's lives are all in great danger. Contents of the invention [0003] In order to solve the above problems, the present invention provides an underground flame retardant power cable with simple structure, low laying requirements, low production cost, low smoke and flame retardant. [0004] The technical solution of the present invention is: the cable includes three insulated cores, the insulated cores are composed of a conductor and an in...
