OPGW Optical Cable is primarily used by the electric utility industry, placed in the secure topmost position of the transmission line where it “shields” the all-important conductors from lightning while providing a telecommunications path for internal as well as third party communications. Optical Ground Wire is a dual functioning cable, meaning it serves two purposes. It is designed to replace traditional static / shield / earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes.
Stranded stainless steel tube OPGW, Central Al-covered stainless steel tube OPGW, Aluminum PBT Loose Tube OPGW are three typical designs of OPGW optical cables.
