Problems solved by technology

[0002]Traditional overhead cables do not have high-efficiency, energy-saving, high-conductivity expanded-diameter conductors, and the insulation layer does not use improved weather-resistant overhead insulation materials, and there is no moisture-proof and reflective layer extruded on the outermost layer , When used in harsh weather environments such as the field, the open air, and strong sunlight, the cable itself consumes a lot of energy, has poor weather resistance, poor insulation performance, and large damage caused by ultraviolet radiation.

Traditional overhead cables have large consumables per unit length, high cost, low cost performance, backward technology, and waste of labor

[0003] The traditional overhead cable production technology has the following problems: 1) The conductor processing technology is backward, and there is no design of a high-efficiency, energy-saving, high-conductivity and expanded-diameter conductor, which consumes a lot of energy; 2) The insulating material is a traditional material, which has not been improved and has poor weather resistance ; 3) The traditional overhead cable insulation layer is not extruded with a moisture-proof reflective layer, which will easily lead to moisture in the insulation, water branches, and large ultraviolet radiation damage; 4) Consumables per unit length are large, costly, and cost-effective; waste of national resources and social labor
