OPGW(Optical Fiber Composite Overhead Ground Wire)

The optical fiber placed in overhead high voltage transmission line in the ground, to constitute a transmission line.

Product Features

It use stainless steel loose tube structure. Increasing its reliability and the performance of temperature-resistant;The OPGW meets the requirement of large count fiber line application. It can be specially used for the communication system in synchronism with the building of electronic transmission line.OPGW cable mainly can be used in 500 KV, 220 KV, 110 KV voltage grade lines.
