The invention discloses an insulating high-temperature-resistant cable which comprises conductors, insulation layers, wrapping tape, an inner protection coat, a heat resistance layer and an outer protection coat, wherein one conductor or a plurality of conductors are arranged; the number of the insulation layers equals to that of the conductors, and the outside of each conductor is coated with an insulation layer; one piece of wrapping tape is provided and coats the whole insulation layers; and the inner protection coat and the outer protection coat are sequentially coated by the wrapping tape, and the heat resistance layer is arranged between the inner protection layer and the outer protection layer. The insulating high-temperature-resistant cable has the advantages of being high-temperature-resistant, cold-resistant, erosion-resistant, oil-resistant, high in flame retardancy, good in insulating property and the like, is higher in reliability and longer in service life when being compared with an ordinary insulative polrvinyl chloride cable especially in high-altitude, big-temperature-difference and corrosive environment, is applicable to places such as petroleum, chemical industry, electricity generation, high-rise buildings, metallurgy, space light and aviation, and is used as a power transmission wire in high-temperature, low-temperature, acid, alkali, oil, water and erosion gas bad environment.
Description
technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to an insulated high temperature resistant cable. Background technique [0002] For petroleum, chemical industry, power generation, high-rise buildings, metallurgy, aerospace and other places, insulated and high-temperature resistant cables for power transmission lines in high temperature, low temperature and harsh environments of acid, alkali, oil, water and corrosive gases need to have high temperature resistance and cold resistance. , Corrosion resistance, oil resistance, high flame retardant, excellent insulation properties and so on. Ordinary polyvinyl chloride insulated cables can meet the above requirements, but in high altitude, large temperature difference and corrosive environments, ordinary polyvinyl chloride insulated cables have poor reliability and short service life. Contents of the invention [0003] The purpose of the present invention is to pro...
