Deicing cable

Abstract

The invention belongs to the technical field of cable manufacturing, and provides a deicing cable. The deicing cable is composed of inner cable cores, an insulation protective layer, outer cable cores, fillers and a frost-proof layer. The peripheries of the inner cable cores are covered with the insulation protective layer, the outer cable cores are distributed in gaps among the inner cable cores, heat generated after the outer cable cores are charged with electricity can deice effectively, and the frost-proof layer can effectively prevent the outer portion of the cables from being frozen. The deicing cable is reasonable in structural design, weight of the cable is reduced, and the deicing cable can deice and keep warm in normal electricity transmission, is good in frost-proof effect, can fast and effectively remove ice layers on the outer portion of the cable, is good in electric current transmission effect, good in weather ability and high in electric energy transmission efficiency, has certain rigidity, is good in torsional property, improves flexibility, can meet various requirements for electrical property and mechanical property, is simple in structure and good in practicability, and has good popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of cable manufacturing, and in particular relates to a deicing cable. Background technique [0002] It is very difficult to maintain cables in cold field areas, especially in areas with frequent snow and rain, where ice is easy to form on cables, and ice accumulation greatly reduces the efficiency of cable transmission of electric energy. [0003] The deicing cable provided by the prior art generally wraps an outer cable core around the inner cable core, and the heat generated by electrifying the outer cable core is used for deicing. The deicing effect is poor, and the weight of the cable is likely to increase due to ice accumulation, thereby Caused the rise of cable breakage rate, simultaneously the structure of this deicing cable is unreasonable, the transmission efficiency of electric energy is low, and energy waste is serious.

Problems solved by technology

[0004] The purpose of the present invention is to provide a deicing cable, which aims to solve the problem that the deicing cable provided by the prior art generally wraps an outer cable core around the inner cable core, and the heat generated by electrifying the outer cable core is used for deicing. The ice effect is not good, and the weight of the cable is likely to increase due to ice accumulation, which leads to an increase in the cable breakage rate. At the same time, the structure of this deicing cable is unreasonable, the transmission efficiency of electric energy is low, and the energy waste is serious.
