Description :

　　OPGW optical cable, OPGW power optical cable description:

　　The definition of OPGW fiber optic cable is Optical Fiber Composite Overhead Ground Wire (also known as Fiber Composite Overhead Ground Wire). Placing optical fibers in the ground wire of overhead high-voltage transmission lines to form an optical fiber communication network on the transmission lines, this structural form combines the dual functions of ground wire and communication, and is generally referred to as OPGW optical cable.

　　OPGW optical cables are mainly used on 500KV, 220KV, and 110KV voltage level lines. Due to factors such as power outages and safety, they are often applied on newly built lines.

　　The applicable characteristics of OPGW are:

　　Lines with high voltage exceeding 110kV have a large span (generally above 250M);

　　Easy to maintain, easy to solve for line crossing problems, and its mechanical characteristics can meet the requirements for large line crossings;

　　The outer layer of OPGW is metal armor, which has no effect on high-voltage corrosion and degradation;

　　OPGW must be powered off during construction, and the losses caused by power outages are significant. Therefore, OPGW should be used in the construction of new high-voltage lines above 110kV;
