60 Core High Voltage Transmission Lines OPGW Optical Ground Wire G.655

 
60 Core High Voltage Power Transmission Line OPGW Optical Ground Wire
 
Description
 
OPGW is primarily used by the electric utility industry, placed in the secure topmost position of the transmission line where it “shields” the all-important conductors from lightning while providing a telecommunications path for internal as well as third party communications. Optical Ground Wire is a dual functioning cable, meaning it serves two purposes. It is designed to replace traditional static / shield / earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes. OPGW must be capable of withstanding the mechanical stresses applied to overhead cables by environmental factors such as wind and ice. OPGW must also be capable of handling electrical faults on the transmission line by providing a path to ground without damaging the sensitive optical fibers inside the cable.

Features

1. Small diameter, low weight reduces retrofit impact
2. Hermetically sealed stainless steel tubes provide mechanical and thermal protection for fibers
3. Thick-walled aluminum pipe provides crush resistance and boosts fault current rating
4. Replacement with ACS wires improves lightning resistance
5. Lower wind and ice loads put less load on structures
6. Fiber grouped in bundles of 12 for ease of splicing
