Composite insulating copper plastic composite tube shielding coaxial cable

Abstract

The invention relates to the technical field of communication cables, in particular to a composite insulated copper-plastic composite tube shielded coaxial cable, which includes an inner conductor, a double-layer composite insulating layer, a copper-plastic composite tube and an outer sheath. The double-layer composite insulation layer is coated on the inner conductor, and the double-layer composite insulation layer is composed of an FPE insulation layer and a nylon coating insulation layer, and the nylon coating insulation layer is outside the FPE insulation layer; the FPE insulation layer Made of expanded polyethylene material. The copper-plastic composite pipe is covered on the outside of the double-layer composite insulating layer, and the copper-plastic composite pipe is composed of a longitudinally wrapped copper-plastic composite tape; the outer sheath is covered on the outside of the copper-plastic composite pipe, and the outer sheath is made of poly Made of ethylene material, a composite insulated copper-plastic composite tube shielded coaxial cable of the present invention, because the cable uses foamed polyethylene and nylon-plated outer film for composite insulation, the cable foams evenly and the surface is smooth and round, so that the cable The impedance is uniform and the working frequency is high, up to 6GHz.

Description

technical field [0001] The invention relates to the technical field of communication cables, in particular to a composite insulated copper-plastic composite tube shielded coaxial cable. Background technique [0002] Most of the coaxial cable insulation methods use semi-air insulation, and most of the semi-air insulation is foamed polyethylene (FPE). The working frequency of foamed polyethylene insulated coaxial cables is not too high, generally 1GHz is the best It can only reach 2GHz; although the working frequency of polyperfluoroethylene propylene (FEP) and polytetrafluoroethylene (PTFE) can reach 6GHz, the sintering molding used in the processing of FEP and PTFE is troublesome in processing and low in production efficiency. There will be toxic substances in the process of processing, and it needs to be well protected and ventilated during the process of processing, and the price is expensive. Therefore, in order to solve the problem of high-frequency (6GHz) coaxial insul...
