OPGW optical cable provides the best transmission medium for power system communication with its high reliability, long life, good safety and many other advantages. As a systematic project, it not only depends on the quality of the OPGW optical cable itself, but also is closely related to the application conditions, line conditions, fittings and standard construction. OPGW optical cable: optical fiber composite frame fiber composite overhead ground wire, OPGW optical cable generally adopts aluminum tube type, aluminum frame type and (stainless) steel tube type structure. The design of OPGW optical cable fully considers the actual power line and the new high-voltage transmission line. For the user needs of different tensile strength and different short-circuit current parameters, we can carefully design matching products to achieve mechanical and electrical requirements.

Using advanced stainless steel tube production technology, the tube is filled with water blocking compounds to effectively protect the optical fiber;

2 By optimizing the design of the optical fiber excess length in the stainless steel tube and the twisting pitch of the cable core, the optical fiber in the optical cable can obtain the secondary excess length to ensure that the optical fiber is not stressed when the opgw optical cable is subjected to the maximum operating tension;

3 The structure is compact, which not only reduces the ice load and wind load, but also ensures that the heat generated in the case of short circuit is easy to dissipate;

4. The outer diameter and tensile force ratio of the optical cable are similar to the common ground wire specifications, and can be used to directly replace the original ground wire without changing the line or replacing the tower;

5 Since it is basically the same as the traditional overhead ground wire, the erection of the opgw optical cable is very convenient;
