Detailed Product Description


 

Construction:

Stainless-steel optical fiber unit

Center tube or layer strand structure

Aluminum alloy wire and aluminum clad steel wire armored

Coated with anticorrosive grease between layers
Product properties:

Fibers are housed in stainless steel tube lead to high reliability

OPGW can support heavy load and long span installation

OPGW can meet the ground wires requirement of mechanical and electric by adjusting proportion of steel and aluminum.

Easy to produce the similar specification of exist ground wire. can replace the exist ground wire
Applying field:
Replace the exist ground wire of exist high voltage power transmission line

Applying properties
lighting protection and conduct the short circuit current

Optical fiber communication ability

Adapt to replace the aged ground wire and new construction of high voltage ground wire
