Abstract

The invention relates to the technical field of traffic power cable and discloses a single core rail transit power cable with a rated voltage of 35KV, the power cable comprises a conductor core, the periphery of the conductor core comprises a conductor shielding layer, an insulating layer, a shielding and insulating layer, a metallic shielding layer and an external protection layer in sequence, the power cable is characterized in that the power cable comprises a vertical water-stopping layer and a radial waterproof layer which are arranged between the metallic shielding layer and the external protection layer in sequence. According to the invention, heat resistance, oxidize resistance, side pressure resistance, mechanical property, waterproof property, fireproof property, ultraviolet light-proof property and ant and rat infestation resistance of the cable can be greatly improved, and in a process of power transmission and distribution, the cable comprises characteristics of high power transmission capacity, long distance and less line loss; the product has advantages of light in weight, simple structure, convenient use, chemical attack resistance, no limit of head drop during the cable laying and the like; and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the field of traffic power cables, and mainly relates to rail transit power cables with a rated voltage of 35KV. Background technique [0002] With the rapid development of my country's economy, the government is vigorously strengthening the construction of various social public supporting facilities, so that more and more high-tech applications are applied in rail transit, and the requirements for supporting facilities such as wires and cables are also getting higher and higher. , so the wire and cable produced by the original technical level can no longer meet the needs of the development of rail transit, which requires the wire and cable companies to introduce and develop new technologies and new equipment to meet the needs of my country's rail transit development, thereby contributing to the development of my country's economy The rapid development has laid a solid foundation. [0003] In the urban rail transit power supply ...
