Anti-static cable

Abstract

The present invention belongs to the field of the network cable technology, and specially relates to an anti-static cable. A bismuth high-temperature supper tape coating a copper core is arranged between the copper core and an external insulation protective layer, the periphery of the bismuth high-temperature supper tape is coated with tubular high-voltage ceramic insulator, and a high-temperature superconductive mask tape is arranged outside of the high-voltage ceramic insulator; there is provided a copper net shielding layer arranged between the high-temperature superconductive mask tape and the external insulation protective layer, and a high-temperature superconductive insulating layer is disposed between the copper net shielding layer and the external insulation protective layer; an inner constant temperature layer is arranged at the inner side of the high-temperature superconductive insulating layer, and an outer constant temperature layer is arranged at the outer side of the high-temperature superconductive insulating layer; and a liquid nitrogen coolant is disposed between the inner constant temperature layer and the high-temperature superconductive mask tape, and the external insulation protective layer is made of polytetrafluoroethylene. Compare with the prior art, the anti-static cable is reasonable in design and structure, high in safety, high in intensity and not easy to damage.

Description

technical field [0001] The invention belongs to the technical field of network cables, in particular to an antistatic cable. Background technique [0002] With the rapid development of economy and society, there are more and more residential areas and office buildings, and the number of cables used is gradually increasing. Existing cables are generally made of all copper or all aluminum. Since copper cables are superior to aluminum in oxidation resistance, welding performance and electrical conductivity, they are widely used in transmission cables with large currents. When the current flows, it will generate heat, which will cause the cable to be burned and damaged, and the existing cable is prone to static electricity, which poses a safety hazard. [0003] For example, Chinese patent literature discloses an electric wire [application number: 201120191172.3], comprising: a conductor formed by twisting and twisting two or more copper single wires; a wrapping layer wrapped ar...

Problems solved by technology

[0004] Although the above solution has a longer service life and is more in line with the social development requirements of environmental protection compared with the electric wires in the prior art, there are still technical problems such as unreasonable design and poor safety.
