OPGW the optical fiber composite overhead ground wire is an overhead ground wire containing optical fiber. It has multiple functions such as overhead ground wire and optical communication. It is mainly used for communication lines of 110kV, 220kV, 500kV, 750kV and new overhead high-voltage transmission systems. It can also be used to replace the existing ground wire of the old overhead high-voltage transmission system, increase the optical communication line, conduct short-circuit current and provide lightning protection. Special structures can be customized according to user needs.


♦ It has the dual functions of ground wire and communication cable, eliminating the huge cost of repeated installation and maintenance;
♦ Installed on the top of the power overhead line tower, no need to consider the factors such as the best hanging point and electrical corrosion;
♦ During the transformation of the old line, the outer diameter and tension singlet ratio of the optical cable can be well matched with the other ground line;
♦ Large transmission capacity, high communication quality and good reliability;
♦ The tensile strength and short-circuit current capacity are large, and the best balance between mechanical and electrical properties can be achieved;
♦ Good safety performance, long service life and not susceptible to damaging damage;

♦ Small cable diameter, light weight and low additional load on the tower
