OPGW products integrate ground wire and optical communication functions: mainly used for communication lines of newly built overhead high-voltage transmission systems of 35KV, 110KV, 220KV, 500KV, 750KV and above
OPGW cable (Optical Fiber Composite Overhead Ground Wire) is an optical cable that combines optical fiber and metal wire.
It is usually used on the grounding wire of power transmission lines, which can not only provide grounding protection for the power system, but also transmit high-speed optical signals. The structure of OPGW optical cable generally consists of an optical fiber unit, a metal core, an insulation layer and a sheath layer. The optical fiber unit is usually composed of one or more optical fibers and is used to transmit optical signals.
The metal core is generally made of aluminum alloy or steel core aluminum stranded wire, which is used to transmit power and provide grounding protection. The insulation layer is used to protect the optical fiber and metal core from the external environment. Commonly used insulation materials include polyethylene and polypropylene. The sheath layer is used to protect the entire optical cable from external physical damage. The main features of OPGW optical cable include high strength, high tensile strength, good corrosion resistance, low transmission loss and anti-electromagnetic interference.
It can transmit power and optical signals simultaneously on power transmission lines, realizing the dual functions of grounding protection and communication transmission of power systems. Due to its ability to resist extreme weather conditions and the influence of the external environment, OPGW optical cable plays an important role in the stable operation of power systems and the reliability of communication transmission. In general, OPGW optical cable is an optical cable that combines power and communication functions. It is widely used in the grounding wire of power transmission lines to provide grounding protection and reliable communication transmission for power systems.
