540 Welded Aluminum Tube Coaxial Cable
Description
540 welded aluminum tube coaxial cable is an aluminum tube series physical foamed polyethylene insulated, aluminum tube outer conductor coaxial cable, suitable for CATV trunk line projects. The inner conductor uses copper-clad aluminum, and the outer conductor uses an aluminum tube, with the same thermal expansion coefficient and elastic modulus, reducing faults. Compared to conventional cables, it has better shielding attenuation, higher return loss, and lower attenuation.
