OPGW Outdoor Aerial Fiber Optic Cable

Product Model: OPGW Outdoor Aerial Fiber Optic Cable
Product Description: OPGW is an overhead ground cable with built-in fibers, owing mutual functions of overhead ground cable and optical communication. It’s mainly applied to communication lines that cross 110kV, 22kV, 500kV, 750kV, and newly built aerial high-voltage power transmission systems. It also can be used to replace existing ground cables in old aerial high voltage power transmission systems, increase new optical communication lines, transport short circuit electricity, and protect it from thunder.

Relatively large cable diameters can design large fiber counts
Stable structure, high reliability
Good tensile and large short-circuit electricity capacity can reach the best balance between mechanical and electrical performance
can match with normal ground wire
