Environment-friendly low-attenuation RG11 coaxial cable

Abstract

An environment-friendly low-attenuation RG11 coaxial cable comprises an inner conductor, a foaming insulation layer, an outer conductor and an outer shield sleeve; the outer conductor is formed by a copper foil layer and a copper wire weaving shielding layer; and the inner conductor, the foaming insulation layer, the copper foil layer, the copper wire weaving shielding layer and the outer shield sleeve are sequentially arranged along the radial direction from inside to outside. Copper is better than aluminum in conductivity, and the copper foil is adopted as the outer conductor of the coaxial cable, so the attenuation of the cable is reduced, and the transmission property of the cable is improved; and the outer conductor structure of the copper foil layer and the copper wire weaving shielding layer is adopted, thus greatly reducing the transfer impedance, improving the attenuation index and realizing excellent antijamming performance. The outer shield sleeve adopts the polyvinyl chloride or polyethylene shield sleeve, according with the environment protection demands of European Union, so the environment protection performance of the whole coaxial cable is ensured.

Description

(1) Technical field [0001] The invention relates to a cable, in particular to an environmentally friendly low-attenuation RG11 coaxial cable. (2) Background technology [0002] The outer conductor structure of the traditional RG11 series coaxial cable is generally double-sided self-adhesive aluminum foil + aluminum-magnesium alloy wire braided structure. For the application requirements of some EU countries, it has the following shortcomings: [0003] 1. Since the transmission distance is required to be longer, the attenuation of the coaxial cable is required to be lower. The traditional RG11 coaxial cable cannot meet its application requirements. [0004] 2. In addition, due to the different sizes of the interface accessories, the coaxial cable foaming process is difficult. [0005] 3. Higher requirements for anti-interference performance. [0006] 4. The traditional RG11 series coaxial cable is suitable for general occasions. For EU countries, it must fully meet the EU's environment...
