Product 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.
Application:
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
