Problems solved by technology

In the actual application process, the control cable, especially the insulation layer in the control cable, has less research and development in terms of heat conduction and flame retardancy. The insulation layer may burn at a higher temperature, which will affect the normal operation of the control cable. Work safety and reliability are difficult to guarantee

Abstract

The invention discloses a high-performance control cable which comprises a cable core. An insulating layer, a temperature decreasing lining layer, a flame retardant layer, a metal armoring layer and a sheath layer are sequentially arranged outside the cable core. The insulating layer is made of a low-smoke zero-halogen polyolefin material which is prepared from, by weight, polyvinyl chloride, a propylene-vinyl copolymer, methyl vinyl silicone rubber, tetra propyl phenylsulfonyl, isopropyl tri(pyrophosphoric acid) titanate, caprolactam, magnesium oxide, 2,4-dichlorobenzoyl peroxide, alkylated diphenylamine, 2-mercaptobenzimidazol zincate, magnesium stearate, kieselguhr, ceric oxide, polyvinyl chloride nitrile fibers, anti-aging agents and antioxidants. The cable is good in thermal conductivity and excellent in flame retardant performance.

Description

technical field [0001] The invention relates to the technical field of control cables, in particular to a high-performance control cable. Background technique [0002] In various industrial and mining enterprises, transportation and other important economic sectors, such as power plants, substations, power lines and petrochemical enterprises, control cables are widely used. For the operation of safe power supply and production systems, the functions of control cables even exceed Power cables for main lines. In the actual application process, the control cable, especially the insulation layer in the control cable, has less research and development in terms of heat conduction and flame retardancy. The insulation layer may burn at a higher temperature, which will affect the normal operation of the control cable. Job security and reliability are difficult to guarantee. Contents of the invention [0003] The invention provides a high-performance control cable with good therma...
