Novel high-temperature-resistant special cable

Abstract

The invention discloses a novel high-temperature-resistant special cable. The novel high-temperature-resistant special cable comprises cable cores, a wrapping layer and a sheath layer, wherein the wrapping layer is arranged outside the cable cores and is formed by wrapping a high-flame-resistance gummed cloth tape; the sheath layer is arranged outside the wrapping layer; a plurality of cable cores are arranged; an insulation layer and an insulation high-temperature-resistant layer are arranged outside the cable cores; the insulation high-temperature-resistant layer is arranged on the outer side of the insulation layer; the sheath layer comprises a flexible framework and a steel wire mesh; the flexible framework is arranged on the outer side of the wrapping layer in a rhombic-grid-shaped arrangement manner; the steel wire mesh is arranged in a rhombic space in the flexible framework. The novel high-temperature-resistant special cable has the advantages of high carrying current, high temperature resistance and high oxidation resistance; the design of three high-temperature-resistant layers comprising filling, the wrapping layer and the insulation high-temperature-resistant layer is adopted; the filling, the wrapping layer and the insulation high-temperature-resistant layer are combined together, so that the high temperature resistance of the cable is greatly improved; the sheath layer adopts the design of combination of the flexible framework and the steel wire mesh, so that the bending resistance and the torsion resistance of the cable can be greatly improved.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to a novel high temperature resistant special cable. Background technique [0002] The cable is usually a rope-like cable made of several or several groups of wires, each group is twisted with at least two wires, each group of wires is insulated from each other, and is often twisted around a center, and the entire outer surface is covered with a high degree of insulation the covering layer. Special cables are a series of products with unique properties and special structures, which are equivalent to ordinary wires and cables with a large quantity and a wide range. They have the characteristics of high technical content, strict service conditions, small batches, and high added value. Due to the high temperature in some production environments, the transmission line is rapidly aging due to the special environment, which seriously reduces the service life of the cable, and the...

AI Technical Summary

Problems solved by technology

Due to the high temperature in some production environments, the transmission line is rapidly aging due to the special environment, which seriously reduces the service life of the cable, and the electrical equipment cannot operate normally. The conventional cable cannot meet its special environment and has a short life. Replacing cables not only affects production but also increases economic costs. Therefore, in these environments, higher temperature resistance requirements are put forward for cables, and conventional special cables cannot meet the requirements for production and use.
