OPGWs combine the functions of grounding and communications in electrical power delivery applications. The OPGW cable is run between the tops of high-voltage electricity pylons. The conductive part of the cable serves to bond adjacent towers to earth ground and shields the high-voltage conductors from lightning strikes. The optical fibers within the cable can be used for high-speed data transmission.
According to Siraj Bhattacharya, solution manager (OPGW) at Sterlite Technologies, "Our existing strengths in fiber-optic cables and power conductors engineering, complemented with our domain knowledge in integrating the total solution, is in line with expectations from our customers to provide a data transfer solution in addition to a power transmission solution. Through our OPGW solution offering, we have operationalized an extremely versatile setup, considering all the design options mapped to geo-technical conditions applicable globally."
