Earlier we used shield wire/sky wire / Ground Wire for protecting the high voltage phase wires from lightning strikes on the Transmission Tower. But today, OPGW is used as shield wire /sky wire/ground wire. It is designed to replace traditional static/shield/earth wires on overhead transmission lines with the added benefit of containing optical fibres which can be used for telecommunications purposes. OPGW serves two purposes: One is to protect the high voltage phase wire on the tower from lightning strikes. Another very important function is transmitting data. It is used form data telemetry from Generating Station to the load dispatch centre. Construction of OPGW: OPGW is optical fibre composite ground wire. This cable contains a tubular structure having one or more optical fibre and surrounded by layers of aluminium and steel wires. This layer of aluminium and steel wires serves to connect the tower to the ground. The optical fibre within the cable is used for the high-speed data telemetry between the utilities or sold to some third parties for high-speed fibre interconnection between the cities. For example, POWERGRID with its brand name ‘POWERTEL’ in Telecom business is the only utility in the Country having overhead optic fibre network using Optical Ground Wire on power transmission lines. Features of OPGW: Through this OPGW Network, Telecom Service providers will be able to provide uninterrupted mobile/Internet services to the people of the state. An optical ground wire is also known as an OPGW or, in the IEEE standard, an optical fibre composite overhead ground wire. It is a type of cable that is used in overhead power lines. 0 Reply Share Share Share on Facebook Share on Twitter Share on WhatsApp Cancel the best answer Leave an answerCancel replyYou must login or register to add a new answer.
