　　Application of OPGW optical cable products:

　　 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.

　　ADSS all dielectric self-supporting optical cable is a non-metallic optical cable composed entirely of dielectric materials, including necessary support systems, and can be directly suspended on power towers. It is mainly used for communication lines in overhead high-voltage transmission systems, and can also be used for communication lines in lightning prone areas, large-span and other overhead laying environments.

　　Product Features

　　 The usage characteristics of OPGW optical cable 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; (5) In the performance indicators of OPGW, the larger the short-circuit current, the more it is necessary to use good conductors 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.

　　 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.

　　Due to its anti electromagnetic interference and light weight, optical fibers can be installed on the top of transmission line towers without considering issues such as mounting position and electromagnetic corrosion. Therefore, OPGW has significant characteristics such as high reliability, superior mechanical performance, and low cost.
