Abstract
The utility model discloses a physical foaming polyvinyl chloride polyethylene sheath coaxial cable and relates to a cable, in particular to a physical foaming polyvinyl chloride polyethylene sheath coaxial cable. The physical foaming polyvinyl chloride polyethylene sheath coaxial cable comprises an inner conductor, wherein a PVC (Polyvinyl Chloride) insulating layer, an aluminum foil screening layer, a tinplating annealed copper wire knitting screening layer and a PVC sheath layer are sequentially arranged outside the inner conductor. The physical foaming polyvinyl chloride polyethylene sheath coaxial cable has the characteristics of high foaming degree, high transmission ratio, good softness, small bending radius, no water permeability, no air permeability, stable impedance, excellent anti-jamming performance and long service life and is mainly suitable for closed circuit televisions, trunk lines for the public antenna television systems and 75ohm coaxial cables for branch lines, user lines and other electronic devices.
Description
Technical field
The utility model relates to a kind of cable, is particularly useful for a kind of physically foamed pe insulation pvc sheath coaxial cable.
Background technology
Radio frequency coaxial-cable has experienced real core polyethylene insulation, chemical blowing polyethylene insulation, vertical hole polyethylene insulation, physically foamed pe insulation four-stage from its evolution.The physical blowing cable is optimal a kind of new high-tech product from its version and performance.Be applicable to that at present main cable, branch cable, service cable and network connect.But common physically foamed pe insulation pvc sheath coaxial cable in application moistureproof ability a little less than, flexibility is lower, is easy to generate loss, and the damage of insulating barrier.
Summary of the invention
The utility model provides a kind of physically foamed pe insulation pvc sheath coaxial cable, purpose be to provide a kind of high foaming rate, waterproof, airtight, flexibility is good, anti-resistance is stable, interference free performance is good, the physically foamed pe insulation pvc sheath coaxial cable of long service life.
The utility model comprises inner wire, outside said inner wire, sets gradually PVC insulating barrier, foil shielding layer, tin annealed copper wire woven shield and PVC restrictive coating.
The utlity model has high foaming rate, high transfer rate, flexibility is good, bending radius is little, waterproof, airtight, anti-resistance is stable, interference free performance is good, the characteristics of long service life.Be applicable to that mainly closed-circuit television, community antenna television system make main line, branch line and subscribers feeder and other use for electronic equipment 75 ohm coaxial cable.
