Problems solved by technology

Physically foamed polyethylene coaxial cables are widely used due to the advantages of no pollution to the environment, high foaming degree, good flexibility, small attenuation constant and stable transmission performance, but the insulating layer of the cable has a certain degree of foaming , low temperature index, not resistant to radiation, flammable, and cannot be used in a nuclear environment
In order to obtain better performance and improve impact strength, etc., it is necessary to use modified polyetheretherketone and other expensive materials, the manufacturing cost is high, and the process is complicated, and the processing and manufacturing is difficult.

Abstract

The invention relates to a coaxial cable which comprises an inner conductor, an insulating layer, a shielding layer and an outer jacket from inside to outside in sequence. The coaxial cable is characterized in that the insulating layer is made of mixed polyether-ether-ketone and glass fiber. The coaxial cable provided by the invention is high in mechanical strength, resistant to radiation and high temperature, reasonable in manufacturing process design, good in working property, simple in process and relatively low in cost.

Description

technical field [0001] The invention relates to the technical field of coaxial cables, in particular to a coaxial cable and a manufacturing process thereof. Background technique [0002] Coaxial cables generally consist of an inner conductor, an insulating layer and a shielding layer, and can also be covered with a protective sheath around the shielding layer. At present, most common coaxial cables use polyethylene as the insulating material. According to the structure of the insulating layer, the development of coaxial cables has experienced solid polyethylene insulated coaxial cables, chemically foamed polyethylene insulated coaxial cables, and longitudinal hole polyethylene insulated coaxial cables. Coaxial cables and physically foamed polyethylene insulated coaxial cables. Physically foamed polyethylene coaxial cables are widely used due to the advantages of no pollution to the environment, high foaming degree, good flexibility, small attenuation constant and stable tr...
