OPGW fiber optic cable parameters

Description :

　　Introduction to OPGW Optical Cable:

　　OPGW optical cable, also known as fiber optic composite ground wire, places optical fibers in the ground wire of overhead high-voltage transmission lines to form a fiber optic communication network on the transmission lines. This structural form combines the dual functions of ground wire and communication, mainly composed of aluminum clad steel, divided into three categories: aluminum tube type, aluminum skeleton type, and (stainless) steel tube type.

　　Characteristics of OPGW optical cable:

　　(1) Lines with high voltage exceeding 110kV have a large span (usually 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;

　　(5) In the performance indicators of OPGW, the larger the short-circuit current, the more good conductors are needed for armor, which correspondingly reduces the tensile strength. However, in the case of a certain tensile strength, to increase the short-circuit current capacity, the only way is to increase the metal cross-sectional area, resulting in an increase in cable diameter and weight, which poses a safety issue for the strength of the transmission tower.

　　Dazheng Electric Wire Co., Ltd. is located in Dazheng Industrial Zone, Renqiu City. The company mainly produces steel core aluminum stranded wire, OPGW optical cable, aluminum clad steel stranded wire, overhead insulated wire, OPPC optical cable, ADSS optical cable, aluminum clad steel core aluminum stranded wire, steel stranded wire, and aluminum stranded wire, with a total of more than 100 varieties and more than 3000 specifications. Located near Baiyangdian, the pearl of North China, the 106 National Highway, Beijing Kowloon Railway, and Jinbao Highway run through the city. It is 156km north of Beijing and 120km east of Tianjin, making transportation very convenient

　　DaZheng Electric Wire Co., Ltd. takes "meeting customer requirements and enhancing customer satisfaction" as its purpose, and "quality is life, integrity is fundamental, and customers are God" as its business philosophy. It cultivates the market, improves product quality, and constantly pursues the perfection of products and services to meet customers' higher requirements.
