The invention relates to a 1kV concentric conductor power cable. The cable comprises a conductor; the exterior of the conductor is provided with an insulating layer, so that an insulating wire core can be formed; the insulating wire core is wrapped with a wrapping tape in an extruded manner, so that a cable core can be formed; and the exterior of the cable core is provided with a shielding layer and a sheath layer sequentially. The 1kV concentric conductor power cable of the invention has the advantages of simple structure, stable transmission, low production cost and long service life.
Description
technical field [0001] The invention relates to a cable, in particular to a 1kv concentric conductor 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 a 1kv concentric conductor power cable with simple structure, stable transmission, low production cost and long service life. [0004] The technical solution of the present invention is: the cable includes a conductor, an insulating layer is arranged outside the conductor to form an insulated core, and the...
