Opgw Cable / O Cable / Power Cable / Optical Fiber Composite Overhead Ground Wire

OPGW optical cable application:
1. OPGW optical cable is mainly used on 110KV, 220KV, 550KV voltage level lines, and is mainly used on new lines due to the influence of line power outages and safety.
2. The line with high voltage exceeding 110kv has a large gear distance (generally above 250M);
3. Easy to maintain, easy to solve the problem of line crossing, its mechanical characteristics can meet the large line crossing;
4. The outer layer of OPGW is metal armor, which has no effect on high voltage electrical corrosion and degradation;
5. OPGW must be powered off during construction, and the power loss is large, so OPGW should be used in new high-voltage lines above 110kv;

OPGW optical cable features:
1. The use of advanced stainless steel tube production technology, the tube is filled with water blocking compounds, which can effectively protect the optical fiber
2. Good structure compactness, high tensile strength
3. The short circuit current has little mutual interference between the power grid and the communication network
4. The excess length of the optical fiber and the twisting pitch of the cable core ensure that the OPGW optical cable is not stressed during the running tension
5. It is similar to the commonly used ground wire specifications, it is very convenient to set up and can directly replace the original ground wire
