Fluoroplastic polymer insulation high temperature-resistant cable

Abstract

The invention discloses a fluoroplastic polymer insulation high temperature-resistant cable, which is formed by four insulation cable cores, a fluoroplastic polymer outer sheath, a copper clad steel shielding layer, a high-temperature glass fiber wrapping layer, a ceramic fluororubber insulation layer and galvanized copper core conductors; each insulation cable core is formed by extruding the ceramic fluororubber insulation layer on the galvanized copper core conductor; the four insulation cable cores are extruded to a cable core by the high-temperature glass fiber wrapping layer; an I-shaped enforcement frame is arranged in the cable core; inflaming retarding glass fiber rope fillers are arranged in gaps between the cable core and the I-shaped enforcement frame; the fluoroplastic polymer outer sheath and the copper clad steel shielding layer are extruded on the high-temperature glass wrapping layer from outside to inside. The fluoroplastic polymer insulation high-temperature cable has the characteristics of excellent electrical performances, chemical corrosion resistance, high temperature-low temperature resistance, waterproofness, no adhesion, high structure strength, low friction coefficient, difficulty for breaking and well self lubrication.

Description

technical field [0001] The invention relates to cables, in particular to a fluoroplastic polymer insulated high temperature resistant cable. Background technique [0002] So far, petroleum, chemical, power generation, metallurgy and other industrial and mining enterprises have high demand for cables, especially in the harsh environment of high temperature, low temperature and acid, alkali, oil, water and corrosive gas, signal transmission lines of electrical instruments and automatic control systems The fluoroplastic insulation and sheath used in commonly used cables has poor corona resistance. Due to the high hardness of fluoroplastics, the wear resistance is not strong, there is stress cracking, and the structural strength is not high, not tensile, and easy to break , cannot produce large-scale products, and the product has a limited service life. Contents of the invention [0003] Based on the above situation, the object of the present invention is to provide a fluorop...
