36 Core Composite Overhead Ground Wire Stranded Tube Optical fiber OPGW Fiber Optic Cable
Description
OPGW is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission. Its working in power transmission line both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and conducting short circuit currency. The OPGW consist of stainless steel tube optical unit, aluminum cladding steel wire, aluminum alloy wire. It has central stainless steel tube structure and layer stranding structure. We can design the structure according to different environment condition and customers requirements.
