OPGW/Ground Wire


Protection of power lines from lightning overvoltage, construction of optical communication systems.


Central strength member (aluminum-clad Steel wires or aluminum alloy wires)


Optical fiber


Stainless steel tube filled with water-blocking gel


Stranded wires (Aluminum-clad steel wires and /or aluminum alloy wires)
