Description

Used to protect the power lines of voltage 35kV and above from lightning overvoltage and for construction of optical communication systems via optical fiber. Part 1 - Aluminum clad steel wire Part 2 - Optical fiber Part 3 - Stainless steel loose tube filled with hydrophobic gel Part 4 - Stranded aluminum clad steel wires and/or aluminum alloy wires Advantages of OPGW: provides two functions at the same time: protect the power lines from lightning overvoltage and for construction of optical communication systems; high reliability and corrosion resistance of OPGW, extended service life due to the use of modern materials, such as aluminum clad steel wire, which is more resistant to oxidation than galvanized; higher permissible mechanical loads during installation and operation; the maximum possible number of optical fibers in OKGT-s;
