High-voltage-withstanding and corrosion-resistant power cable and voltage withstanding method thereof

Abstract

The invention discloses a high-voltage-withstanding and corrosion-resistant power cable and a voltage withstanding method thereof. The high-voltage-withstanding and corrosion-resistant power cable comprises a cable inner core, a reserved cavity, an outer protection layer, an abutting connecting piece and a preset core layer, wherein the outer end of the cable inner core is in butt joint with the outer protection layer, the reserved cavity is reserved between the cable inner core and the outer protection layer, a nesting piece is mounted on the inner side of the outer protection layer in a nesting mode, and a sliding groove is formed in the inner side of the outer protection layer. According to the high-voltage-withstanding and corrosion-resistant power cable and the voltage withstanding method thereof, heat accumulated in the cable in the power transmission process can be stably conducted to the outside by stably matching the movable butt joint piece and the nesting piece made of the copper material, so that the situation that the cable is heated excessively is avoided; and the movable butt joint piece protruding out of the outside can stably increase the butt joint range of the cable, the effect of a grounding wire is formed when the movable butt joint piece and the ground position are installed, and the insulating performance of the cable is effectively guaranteed in cooperation with tetrafluoroethylene gas in the reserved cavity.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a high-voltage-resistant corrosion-resistant power cable and a voltage-resistant method thereof. Background technique [0002] With the continuous development of my country's power industry, various types of power equipment are gradually increasing, among which power cables are one of the more common basic equipment for telecommunication transmission, which determines various indicators of telecommunication transmission, etc., so the technical requirements are gradually increasing. Quality is required, but the existing power cables still have certain defects, such as: [0003] 1. For example, the environment-friendly anti-termite power cable with the publication number CN202584905U solves the pollution of the environment by traditional toxic substances, the damage to the ecology, and the physical damage to the production personnel, and has good environmental performance.

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a high-voltage-resistant corrosion-resistant power cable and a voltage-resistant method thereof, so as to solve the problem that it does not have good voltage-resistant performance in the above-mentioned background technology, which causes it to be subjected to damage during use in a special environment. In the case of excessive voltage, it is easy to have bad phenomena such as breakage, and the protection efficiency is not high enough, which leads to the inability to guarantee the insulation quality, and is prone to dangerous phenomena such as leakage. At the same time, its corrosion resistance is limited and its use is limited.
