Abstract

The invention relates to the technical field of a RG-6 copper-coated steel coaxial cable fabrication process, in particular to a RG-6 copper-coated steel coaxial cable. The RG-6 copper-coated steel coaxial cable comprises a copper-coated steel conductor, an inner skin layer, a foam layer and an outer skin layer, wherein the raw material for fabricating the inner skin layer comprises the followingconstituents based on parts by weight: 0.3-0.7 part of ethylene-ethylhexyl copolymer and 23-27 parts of low-density polyethylene, the raw material for fabricating the foam layer comprises the following constituents based on parts by weight: 23-27 parts of HDPE 2911, 23-27 parts of HMA, 23-27 parts of low-density polyethylene and 0.3-0.7 of nucleating agent, and the raw material for fabricating theouter skin layer comprises the following constituents based on parts by weight: 0.3-0.7 part of ethylene-ethylhexyl copolymer and 23-27 parts of low-density polyethylene. The fabricated RG-6 copper-coated steel coaxial cable has the advantage of small transmission attenuation, and the signal transmission quality of the coaxial cable is favorably improved.

Description

technical field [0001] The invention relates to the technical field of RG-6 copper-clad steel coaxial cable preparation technology, more specifically, it relates to an RG-6 copper-clad steel coaxial cable and a preparation method thereof. Background technique [0002] Recently, in a wireless communication environment, coaxial cables have been used to transmit UHF signals because of their low signal attenuation characteristics. In the high-frequency band, coaxial cables have favorable characteristics such as stable impedance. It has been widely used in the field of signal transmission. At present, in the cable industry, coaxial cables can be divided into RG-58, RG-6, RG-11 and other specifications. According to the EN50117-2-4 standard, the inner core wire of the RG-6 specification coaxial cable generally has a diameter of 1.02 mm copper-clad steel is the inner conductor. The inner skin layer and insulating layer of the RG-6 coaxial cable are generally made of polyethylene...
