　　Characteristics analysis of OPGW optical cable:

　　The main feature of OPGW is its dual function of ordinary ground wire and communication optical cable, achieving dual effects of lightning protection and communication. It is suitable for transmission lines with voltage levels of 110kV and above. It also has the advantages of high tensile strength, strong resistance to destructive weather conditions such as wind, ice, lightning strikes, etc., accommodating a large number of optical fibers, long service life, and high reliability.

　　OPGW optical cable has achieved excellent results in practical application in China for more than 20 years.

　　OPGW optical cable, also known as Optical 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: (1) lines with high voltage exceeding 110kV and large span (generally above 250M); (2) Easy to maintain, easy to solve for line crossing problems, and its mechanical characteristics can meet the requirements for large line crossings; (3) The outer layer of OPGW is metal armor, which has no effect on high-voltage corrosion and degradation; (4) 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;
