Energy-saving and environmental-protection crosslinking power cable

Abstract

A cross-linked energy-saving and environment-friendly power cable, which includes a cable core formed by twisting and winding a plurality of insulated wire cores, and the cable core is wrapped with an inner lining layer, an armor layer and an outer sheath layer in sequence from the inside to the outside. , in the insulated core, the single-filament stranded circular copper conductor of the type wire is wrapped with a high-temperature radiation-resistant cross-linked flame-retardant polyolefin insulating layer; Combustion belt; the inner lining layer is two layers of polyester tape wrapped around the outside of the tape layer; the armor layer is an aluminum alloy tape interlocking armor structure; the outer sheath layer is halogen-free and low-smoke High temperature radiation cross-linked flame retardant polyolefin sheath layer. The cross-linked energy-saving and environment-friendly power cable provided by the present invention can solve the problems of relatively high consumption of existing cable materials, easy damage due to overheating and excessive bending, and secondary harmful pollutants during combustion. It has the advantages of material saving, strong overload capacity, and halogen-free Low-smoke, flame-retardant, fire-resistant, self-locking protection characteristics, the cable operation is safer and more reliable, and the service life is longer.

Description

technical field [0001] The invention relates to the field of cross-linked cables, in particular to a cross-linked energy-saving and environment-friendly power cable. Background technique [0002] With the rapid development of my country's electric power construction, the demand for power cables is also increasing. At present, under the new economic normal, the requirements for power cables are getting higher and higher. Energy saving and environmental protection have become a new direction for the development of power cables. . Therefore, the application and development of energy-saving and environment-friendly power cables is particularly important. [0003] However, the cross-linked power cables produced by most enterprises are common types of power cables, which can only meet the general performance, and the performance of energy saving and environmental protection is poor. , 2, silane cross-linked polyethylene insulation, 3, polypropylene filling rope, 4, polypropylene ...
