Description :
The applicable characteristics of OPGW are:
Lines with high voltage exceeding 110kV have a large span (generally above 250M);
Easy to maintain, easy to solve for line crossing problems, and its mechanical characteristics can meet the requirements for large line crossings;
The outer layer of OPGW is metal armor, which has no effect on high-voltage corrosion and degradation;
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;

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.

application
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
