Abstract

The invention discloses a coaxial cable trunk line with long service life, which comprises an inner conductor. A foam insulator is arranged outside the inner conductor; an outer conductor is arranged outside the foam insulator; a polyvinyl chloride inner sheath is arranged outside the outer conductor; and a polyethylene outer sheath is arranged outside the polyvinyl chloride inner sheath. The coaxial cable trunk line has the advantages that the coaxial cable trunk line has aging resistance and corrosion resistance; and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to a coaxial cable trunk line. Background technique [0002] The structure of the existing coaxial cable main line includes: an inner conductor, a foamed insulator is arranged outside the inner conductor, an outer conductor is arranged outside the foamed insulator, and a polyethylene outer sheath is arranged outside the outer conductor. The existing coaxial cable main line is suitable for use on overhead walls and other occasions. When it encounters harsh environments such as sewer pipes and trench pipes, it is easy to age, corrode, and has a short service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coaxial cable main line with long service life. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: the coaxial cable main line, comprising: an inner conductor, a foamed insulator is arr...
