Abstract
The utility model discloses a cross linked polyvinyl chloride coaxial radio frequency cable, which is composed of insulating wire cores, a fire-resistant wrapping layer and a fluororubber outer sheath, wherein the insulating wire core is formed by extruding an insulating layer on an aluminum alloy stranded conductor; four insulating wire cores extrude a tensile steel wire; the tensile steel wire is externally provided with a polyethylene insulating layer; the fire-resistant wrapping layer extrudes the four insulating wire cores into a cable core; gaps of the cable core are provided with a filling layer; and the filling layer is internally provided with two ground wire cores, and the two ground wire cores are arranged at the outer sides of contact parts of each two adjacent insulating wire cores symmetrically in a mode of taking the cable core as a core. The cross linked polyvinyl chloride coaxial radio frequency cable is simple in structural design and stable in performance, and performance requirements of the radio frequency can be met. In addition, the cross linked polyvinyl chloride coaxial radio frequency cable is flexible, easy to lay, stable in current, abrasion resistant and tension resistant.
