Abstract

The invention discloses a polyvinyl insulating coaxial cable which has a long service life and comprises an inner conductor, wherein an inner conductor sheathing layer is arranged on the outer side of the inner conductor; a polyvinyl insulator is arranged on the outer side of the inner conductor sheathing layer; and polyvinyl insulating sheathing layers are arranged on the outer side of the polyvinyl insulator. The polyvinyl insulating coaxial cable can effectively prevent steam intervention, has prolonged service life, and ensures stability of all performance indexes.

Description

technical field [0001] The invention relates to a cable, in particular to a polyethylene insulated coaxial cable. Background technique [0002] The structure of the existing polyethylene insulated coaxial cable includes: an inner conductor, an inner conductor sheath layer is arranged outside the inner conductor, and a polyethylene insulator is arranged outside the inner conductor sheath layer. The existing polyethylene insulated coaxial cable is only provided with a sheath layer of the inner conductor, which is prone to water vapor, which affects the overall performance index and service life of the polyethylene insulated coaxial cable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a polyethylene insulated coaxial cable with long service life. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a polyethylene insulated coaxial cable, co...
