Coaxial cable for ultramicro signal transmission

Abstract

The invention belongs to a cable, in particular relates to an ultramicro signal transmission coaxial cable which comprises a cable forming layer and a jacket. The ultramicro signal transmission coaxial cable is characterized in that the cable forming layer comprises one or a plurality of coaxial core wires, an insulating layer is arranged outside each core wire conductor, a shielding layer which is formed by knitting tinning copper wires is arranged outside the insulating layer, a low smoke and zero halogen inner jacket is arranged outside the shielding layer, a polyester film is wrapped outside the cable forming layer with one or a plurality of coaxial core wires, and a low smoke and zero halogen outer jacket is arranged outside the polyester film. Compared with the prior art, the invention has the advantages of stable structure, reliable performance, compact volume, environmental protection, no pollution and lower industrial manufacturing cost.

Description

technical field

[0001] The invention belongs to electric cables, in particular to an ultramicro signal transmission coaxial cable. Background technique

[0002] In a telecommunications system, cables are spread throughout the body like human blood vessels, responsible for power supply and signal control transmission to ensure the normal operation of the system. With the rapid development and progress in the field of telecommunications, a large number of applications of electronic and communication equipment, the use of signal transmission cables has increased dramatically. Since the current transmission cables are all manufactured with high technology, the wire diameter is huge, and polyvinyl chloride is used as the sheath, so the anti-interference performance is poor. Therefore, as far as a system is concerned, the cable structure and electrical quality can not only properly handle internal signal transmission, but also completely transmit the internal signal of the system...
