^{OPGW description:}

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

ADSS fiber cables are erect on the same pole with power line in new and old power line.}

^{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}
