Optical Fiber Composite Overhead Ground Wire(OPGW)
http://www.hardware-wholesale.com/s-g652d-opgw-cable-in-transmission-line WebOPGW 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 or provision of anti-lightning protection. 2. 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. Such cable combines the functions of grounding and communications. An OPGW cable contains a tubular structure with one or more … See more An OPGW cable was patented by BICC in 1977 and installation of optical ground wires became widespread starting in the 1980s. In the peak year of 2000, around 60,000 km of OPGW was installed worldwide. Asia, … See more Several different styles of OPGW are made. In one type, between 8 and 48 glass optical fibers are placed in a plastic tube. The tube is inserted into a stainless steel, aluminum, or aluminum-coated steel tube, with some slack length of fiber allowed to prevent strain on the … See more A utility may install many more fibers than it needs for its internal communications both to allow for future needs and also to lease or sell to … See more • "IEEE 1138 Standard Construction of Composite Fiber Optic Overhead Ground Wire (OPGW) for Use on Electric Utility Power Lines". 17 March 1994.
