Abstract

The invention discloses a dual-state temperature change type cold-proof anti-freezing cable and belongs to the cable field. The dual-state temperature change type cold-proof anti-freezing cable includes a core layer, the outer end of the core layer is wrapped with an insulating layer. The outer end of the insulating layer is coated with a sheath; and the outer surface of the sheath is coated witha semi-transparent soft layer. At high temperature, a gas-controlled oil part is partially gasified to generate gas, an outer air bulge bulges outwards and is filled with air, and compared with an entity, the gas conduction speed is lower, the external temperature can be effectively isolated, the overall high temperature resistance of the cable is effectively improved and the service life is prolonged; and at low temperature, light oil returns to liquid, animal oil is cured, the gas-controlled oil part is integrally in a solid state with certain viscosity under the adjustment of the liquid light oil, so that the defect that the outer layer of the cable is hardened and embrittled at low temperature can be effectively overcome, and compared with the prior art, the brittleness resistance of the cable in winter is remarkably improved, and the service life of the cable is further prolonged.

Description

technical field [0001] The invention relates to the field of cables, more specifically, to a dual-state temperature-changing cold-proof and anti-freezing cable. Background technique [0002] The cable is mainly composed of the following 4 parts. ① Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be formed by twisting a single wire or multiple wires. ②Insulation layer: The insulation material used for cables should have high insulation resistance, high breakdown electric field strength, low dielectric loss and low dielectric constant. Commonly used insulating materials in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, cross-linked polyethylene, rubber, etc. Cables are often classified by insulating materials, such as oil-impregnated paper insulated cables, PVC cables, XLPE cables, etc. ③ Sealing sheath: protect the insulated wire c...
