Problems solved by technology

[0002] In actual operation, in the case of heavy snowfall and freezing rain, frost, ice and icicles will form on the surface of the cable, which increases the weight of the overhead insulated cable, resulting in broken wires or towers, and circuit interruption. It brings inconvenience to people's lives and also causes huge losses to the country
At present, anti-icing cables have come out, but in the process of use, there are still problems of short service life and unsatisfactory tensile strength

Abstract

The invention discloses a cold-proof and icing-resistant cable. The cable comprises a core, a shielding layer and an icing-resistant layer which are sequentially arranged from inside out, and the icing-resistant layer is produced from, by weight, 55 parts of fluorosilicon resin, 12 parts of wollastonite nano-powder, 8 parts of polyurethane, 8 parts of SiO2-glass fiber gel, 6 parts of basalt fibers, 5 parts of glass fibers, 5 parts of carbon fibers and 4 parts of polytetrafluoroethylene. The cold-proof and icing-resistant cable has the advantages of long service life and good tensile strength.

Description

Technical field: [0001] The invention relates to the technical field of cables, in particular to a cold-resistant and ice-resistant cable. Background technique: [0002] In actual operation, in the case of heavy snowfall and freezing rain, frost, ice and icicles will form on the surface of the cable, which increases the weight of the overhead insulated cable, resulting in broken wires or towers, and circuit interruption. It brings inconvenience to people's lives and also causes huge losses to the country. At present, anti-icing cables have come out, but they still have the problems of short service life and unsatisfactory tensile strength during use. Invention content: [0003] The technical problem to be solved by the present invention is to provide a cold-resistant and ice-resistant cable with long service life and good tensile strength. [0004] The technical solution of the present invention is to provide a cold-resistant and anti-icing cable, which includes a core, ...
