Problems solved by technology

[0002] High-voltage cables need to isolate the interference of external electromagnetic fields as much as possible during long-distance transmission. The current high-voltage cables cannot overcome it very well.
And at present, high-voltage cables are routinely equipped with a waterproof layer, but different environments have different requirements for cables. When the moisture in the environment is not very high, setting a waterproof layer will cause waste

Abstract

The invention relates to a high-voltage cable with an excellent anti-electromagnetic-interference performance. On the basis of improvement of conductive materials and an external anti-electromagnetic-interference layer, the excellent anti-electromagnetic-interference performance of the high-voltage cable is realized; and the electrical conductivity is improved. Therefore, the conductivity, durability, and applicability of the high-voltage cable are substantially improved.

Description

technical field [0001] The invention belongs to the field of high voltage electricity and the field of materials, in particular to a high voltage cable resistant to electromagnetic interference. Background technique [0002] High-voltage cables need to isolate the interference of external electromagnetic fields as much as possible during long-distance transmission, and the current high-voltage cables cannot overcome it well. At present, high-voltage cables are routinely provided with a waterproof layer, but different environments have different requirements for cables. When the moisture in the environment is not very high, setting a waterproof layer will cause waste. At the same time, high-voltage cables have very high requirements for their electrical conductivity because they need to transmit power remotely, and at the same time require that the power loss be reduced to as low as possible. Contents of the invention [0003] The object of the present invention is to prop...
