Can OPGW power fiber optic cables conduct electricity
The OPGW cable is run between the tops of high-voltage electricity pylons. An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. An OPGW cable contains a tubular structure with. OPGW is mainly applied in communication line of newly constructed high voltage transmit electricity system with 35 KV or above, or replacement of existing ground wire of previous overhead high voltage transmit electricity system, adding of communication lines and conduction of short-circuit current. Electrical utilities have networks used to transmit and distribute electrical power over a large geographic area. In their served areas will be power generating stations, alternative energy sources (solar, wind, geotherman, etc. ), substations for distribution and microgrids.
