Base Station Corrugated Hard-line Feeder Cable

Product Description

50 ohms corrugated copper tube coaxial cable is made on advanced physical foaming insulation production line and argon arc welding, corrugating and slotting production line. Its operation is strictly in compliance with ISO 9001 quality assurance system for quality control of product.

50 ohms corrugated copper tube coaxial cable is mainly used for base station, which include wireless mobile communication, cellular, microwave and broadcast applications as connection of transmitter, receiver and antenna and also connection between wireless communication equipments or other low loss and SWR signal transmission at high frequency. The cables have CCA or solid copper or copper tube conductor, a dielectric of foamed PE with 80% foaming degree which is finished on a three layers co-extruder and consist of skin-foam-skin, outer conductor consisting of corrugated copper tube with good properties such as low attenuation, low VSWR, low temperature, corrosion resistance, good water longitudinally sealed and high power capacity and black weather or flame retardant PE jacket.
