Optical fiber cable OPGW (Optical Ground Wire) is a hybrid overhead cable that combines the role of a transmission line lightning protection conductor (ground wire) with built-in optical fibers for communications. Prysmian has a built-in multi-step quality assurance programme, which covers the entire production process from cable design and raw materials purchasing, to final inspecti tion for any single project. It breaks down the traditional boundaries between. Overhead optical fibre cable systems have become a key factor in telecommunications networks used by operators and power utilities. Due to the fact that no civil works are required and the rights of way have already been established, it is possible to minimise costs and, most importantly, the time. 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. 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.
