Telecommunications OPGW Optical Ground Wire Fiber Composite
OPGW cable is the short for optical ground wire; it is the optical
fiber composite overhead ground wire.
OPGW cable has one or more optical fibers inside, and contains
stainless steel tube, or seamless aluminum tube.
- It is applied on high voltage power transmission lines like 110KV,
220KV, and/or 500KV.
- It can replace traditional static, shield , earth wires on overhead
power transmission lines
- It Shields the high voltage conductors from lightning.
- It provides telecommunications path and the third party
- It provides a path for the transmission of voice, video or data
