Application of OPGW Wire
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.
