Optical cables in 110kV overhead lines
This is an attractive concept for many power utilities because it means that the communications network is under their own control and can be tailored to meet their particular requirements with suitable attributes such as, and. OPGW is a composite cable containing both optical fibers and ground wire conductors. An optical fiber composite overhead ground wire (OPGW) is a new type of ground cable used in the high-voltage power transmission system that serves as both a conventional overhead ground cable and a communication optical cable. They are affected by factors such as power failure, safety and so on, and are mostly applied to new lines. The applicable characteristics of OPGW are: High voltage over 110kV lines have large span (usually above 250M). Optical attached cable (OPAC) is a type of fibre-optic cable that is installed by being attached to a host conductor along overhead power lines.
