Problems solved by technology

At present, the insulation layers of commonly used wire and cable products are mostly PVC, PE and rubber mixtures, which have low temperature resistance and are not suitable for use in high temperature environments. Some high temperature resistant cables on the market have shortcomings: some have poor radiation resistance, Some are not resistant to high temperature water vapor, and some have poor bending performance and are not easy to install, so they are all subject to certain restrictions.

Abstract

The invention provides a novel flame-retardant high-temperature resistant cable. The cable comprises conductors, wherein an inner insulating layer and an outer insulating layer are sequentially arranged outside each conductor, a glass fiber layer is arranged outside each outer insulating layer, and the conductor, the inner insulating layer, the outer insulating layer and the glass fiber layer form an insulated core; a plurality of insulated cores are stranded to form a cable core; an inner flame-retardant layer is arranged outside the cable core; an inner protecting layer is arranged outside the inner flame-retardant layer; an outer flame-retardant layer is arranged outside the inner protecting layer; an outer protecting layer is arranged outside the outer flame-retardant layer; the conductors are golden or nickel conductors; the inner insulating layers and the outer insulating layers are rubber layers; and the inner flame-retardant layer and the outer flame-retardant layer are glass fiber tapes. According to the invention, the conductors are made of silver or copper, both of which are high-temperature resistant conducting materials; each insulated core is provided with a glass fiber layer, so that good insulativity, strong heat resistance, favorable corrosion resistance and high mechanical strength are achieved; and as two flame-retardant layers are arranged outside the cable core, the flame retardant property and the high-temperature resistant property are improved.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a novel flame-retardant and high-temperature-resistant cable applied to power transmission in high-temperature areas. Background technique [0002] In recent years, with the progress of science and technology, such as electromechanical industry, thermal power plant, metallurgy, petroleum, chemical industry, commercial heating and other fields, the demand for some materials in high temperature environment is increasing, such as high temperature resistant wire and cable and other products. At present, the insulation layers of commonly used wire and cable products are mostly PVC, PE and rubber mixtures, which have low temperature resistance and are not suitable for use in high temperature environments. Some high temperature resistant cables on the market have shortcomings: some have poor radiation resistance, Some are not resistant to high temperature water vapor,...
