OPGW fiber cable G652D G655 Self-Supporting Aerial Composite Overhead Ground Wire OPGW Optical Fibre Cable
OPGW is a overhead ground cable with built-in fibers, owing mutual functions of overhead ground cable and optical communication. It’s mainly applied to communication lines which cross 110kV, 22kV, 500kV, 750kV and new built aerial high voltage power transmission system. It also can be used to replace existed ground cable in old aerial high voltage power transmission system, and increasing new optical communication lines, transporting short circuit electricity and protecting it from thunder.
Product Structure
-Relatively large cable diameter, can design large fiber counts
-Stable constructure, high reliability
-Good tensile and large short circuit electricity capacity, can reach a best balance between mechanical and electrical performance
-can match with normal ground wire
-High voltage power transmission system
-Aerial
