OPGW cable is mainly used in the communication line of the new high-voltage transmission system, or to replace the existing ground wire of the original overhead high-voltage transmission system. It contains optical fiber communication lines and has good performance to prevent lightning strikes. OPGW cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements, mostly used in new lines. Its applications are:high pressure over 110kv, with a longer span (usually over 250M).
