Company Profile
Product Details
OPGW cable 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
1.lighting protection and conduct the short circuit current.
2.Adapt to replace the aged ground wire and new structure of high voltage ground wire.
3.For new or existing Ground cable.
