GL Fiber provides for hardware fittings for installation with ADSS fiber cable supporting on the pole. The cable inside the multi-loose tube filled with a water-resistant filling compound or design for water blocked with water blocking material inside the cable. The cable high is tensile by aramid yarns and FRP strength member rod inside. Outer sheath made from HDPE. Of course, there are many specifications of ADSS fiber cables. Let's take a brief look at the ADSS cable of 120m span. The following are the specific parameter details:
