Problems solved by technology

[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. A kind of fault, need a strong anti-freezing ability, good voltage resistance cable

Abstract

The invention discloses an anti-freezing pressure-resistant cable. The anti-freezing pressure-resistant cable comprises a conductor, an insulating layer, a heat conduction layer I, a heating layer, a heat conduction layer II, a shield layer and a sheath. The conductor is externally extruded by the insulating layer. The insulating layer is externally extruded by the heat conduction layer I. The heat conduction layer I is externally extruded by the heating layer. The heating layer is externally extruded by a heat conduction layer II. The heat conduction layer II is externally extruded by the shielding layer. The shielding layer is externally extruded by the sheath. The anti-freezing pressure-resistant cable is simple and reasonable in structure and is effective in freezing resistance.

Description

technical field [0001] The invention relates to a freeze-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 high-end fields including space and ocean, cables will be used. With the development of social economy, cable varieties are constantly updated and improved, and the production volume is also increasing. It continues to increase. Because of 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 and other For this type of fault, a cable with strong frost resistance and good voltage resistance is required. Contents of the invention [0003] In order to overcome the above disadvant...
