Porduct Introduction SYWLY-75 series polythene physieal high-foam coaxial cable with aluminum tube as exterior conducting body is
suitable to be CATV main trunk.Aluminum wrapped by copper acting as inner conducting body and aluminum
tube as exterior conducting body have equivalent heat expansion factor and elastic moduls,greatly reducing the
failure caused by pulling and benging of inner wires of cable .Comparing to the cables with aluminum wire or
knitting wire arraching aluminum membrane,it's superior in good shielding,low attenuation and low return loss.
The parameters of cable are on the same level of similar products in the world. Construction and Dimensions Construction Electricial Performance
