Anti-rat and termite and anti-freeze pressure-proof cable

Abstract

The invention discloses an anti-rat and termite and anti-freeze pressure-proof cable, which comprises a conductor, an insulating layer, a heat-conducting layer 1, a heating layer, a heat-conducting layer II, a fire-retardant layer, an isolating layer, capsule particles, a protective sheath, reflecting strips and light-emitting lines, wherein the insulating layer extrudes and coats the outside of the conductor; the heat-conducting layer I extrudes and coats the outside of the insulating layer; the heating layer extrudes and coats the outside of the heat-conducting layer I; the heat-conducting layer II extrudes and coats the outside of the heating layer; the fire-retardant layer extrudes and coats the outside of the heat-conducting layer II; the isolating layer extrudes and coats the outside of the fire-retardant layer; the protective sheath extrudes and coats the outside of the isolating layer; air pipes are arranged in the isolating layer; and an inert gas is arranged in each air pipe. The cable disclosed by the invention has the anti-freeze and anti-rat and termite advantages and the like.

Description

technical field [0001] The invention relates to a rodent-proof, frost-proof and voltage-resistant cable, which belongs to the technical field of power cables. Background technique [0002] Wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, even in the high-end fields of space and ocean, cables will be used. With the development of social economy, the varieties of cables are constantly updated and improved, and the production volume is also increasing. Due to the application of cables in different fields, people's requirements for them have also increased. The existing cables cannot meet the needs of the industry due to material or structural problems. In cold areas, cables are broken due to low temperature, etc. This type of failure requires a frost-resistant, rodent-proof, and easy-to-repair cable. Contents of the invention [0003] In order to overcome the above disadvantages, the object of the prese...
