^{OPGW description:}

^{1. OPGW cable is the short form of Optical Fiber Composite Overhead Ground Wire.}

^{2.OPGW cable is suit for installation on new power lines with double function of ground wire and communication, especially for installation on normal voltage and extra high voltage}

^{power lines. OPGW can replace conventional ground wire of old power lines with increasing fiber communications function.}

^{3. OPGW cables conduct short circuit current and provide lighting resistance.}

^{4. OPGW cables are usually two structures. The central tube OPGW cable can obtain maximum}

^{optical fiber excess length in a smallest steel tube. The diameter of stainless steel tube is bigger than that of ACSR wire and aluminum alloy wire. The stainless steel tube is placed}

^{in the center of the stranded structure of the OPGW cable. Stranded OPGW cable can obtain secondary excess length; the diameter of stainless steel tube is consistent with diameter of aluminum alloy wire.}

^{OPWG Application:}

^{Optical fiber composite ground wire [OPGW] is suitable for installation on new power lines with double function of ground wire}

^{and communication. Especially for installation on normal voitage and extra high voltage power lines. OPGW can replace conventional ground wire}

^{of old power line with increasing fiber communication function. They conduct short circuit current and provide lightning resistance}
