OPGW ADSS Encolsure
48Cores Central ACS OPGW Cable
Product Introduction
OPGW optical cable structure is mainly composed of optical fiber unit (stainless steel tube, aluminum-clad stainless steel tube) and metal monofilament (aluminum-clad steel, aluminum alloy) peripheral reinforcing ribs. There are 4 types of OPGW cables: ACS (Aluminum Clad Stainless Steel Tube), Stranded Tube, Center Tube and ACP (Aluminum Clad PBT).
Product Parameter (Specification)
● Small cable diameter, light weight, low additional load to the tower;
● The steel tube locates at the center of the cable, no second mechanical fatigue damage.
● Low resistance to side pressure, torsion and tensile (single layer).
