China Professional OPGW Aerial Fiber Optic Cable

Material and structure are uniform, good resistance to vibration fatigue.

Short circuit current has small effect on the optical fiber transmission properties,Good anti-lightning performance.



Introduction

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. 


Applications

  • Adapt to replace the aged ground wire and new structure of high voltage ground wire
  • lighting protection and conduct the short circuit current
  • Optical fiber communication ability
