Problems solved by technology
[0002] DC transmission is especially suitable for long-distance and large-capacity transmission lines. Therefore, it has developed rapidly since its launch. At present, due to the construction of the Global Energy Internet, HVDC transmission will change the grid pattern in the next few decades. However, common Among them, ordinary high-voltage DC wires have poor shielding effect, serious electromagnetic interference, and easy breakdown, which leads to the failure of DC wires to work normally in the high-voltage DC system, which seriously affects daily electricity consumption and industrial production.

The invention discloses a high-voltage copper wire shielding direct-current wire in the technical field of wires, the wire comprises two copper wires with the same structure, each of the copper wiresis covered with a copper wire insulating layer, a copper shielding layer is arranged on the surface of the copper wire insulating layer, insulation filling is arranged on the periphery of the copper shielding layer, a steel shielding layer is arranged on the surface of the insulation filling, an outer insulating layer is arranged on the surface of the steel shielding layer, and a waterproof layeris wrapped on the surface of the outer insulating layer. The direct-current wire in the invention is simple in structure, safe and reliable, and damage to the wires caused by abnormal discharge duringhigh-voltage power transmission can be prevented to the maximum extent, thereby enhancing the safety of the wires.
Description
technical field [0001] The invention relates to the technical field of electric wires, in particular to a high-voltage copper wire shielded DC electric wire. Background technique [0002] DC transmission is especially suitable for long-distance and large-capacity transmission lines. Therefore, it has developed rapidly since its launch. At present, due to the construction of the Global Energy Internet, HVDC transmission will change the grid pattern in the next few decades. However, common Among them, ordinary high-voltage DC wires have poor shielding effect, serious electromagnetic interference, and easy breakdown, which leads to the failure of DC wires to work normally in the high-voltage DC system, seriously affecting daily electricity consumption and industrial production. Contents of the invention [0003] The object of the present invention is to provide a high-voltage copper wire shielded direct current electric wire to solve the problems raised in the above-mentioned...
