OPGW

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.

 

Renewables Optimized OPGW

Renewable energy initiatives such as wind and solar farms have become a routine part of the new global energy business. Like most traditional transmission line projects, Optical Ground Wire is a key component in the planned power grid. Typical renewable applications require smaller, lighter-weight cables that can be delivered with minimal delay.

 

AlumaCore Optical Ground Wire (OPGW)

OPGW – AlumaCore Optical Ground Wire is preferred for its central aluminum pipe and color-coded fiber optic buffer tubes which simplify the splicing process while providing optimum fiber protection as well as long term product reliability.

 

CentraCore Optical Ground Wire (OPGW)

CentraCore OPGW (Optical Ground Wire) is preferred for its compact size and ability to house up to 96 fibers in a diameter starting at only 12mm. Its small profile offers an exceptional solution to the diameter and weight concerns on many of today’s overloaded transmission towers where an existing shield wire needs to be replaced with an OPGW cable.

 

HexaCore Optical Ground Wire (OPGW)

HexaCore OPGW (Optical Ground Wire) cable utilizes fiber-bearing stainless steel tubes stranded alongside aluminum clad steel and/or aluminum alloy wires to create a multi-layer cable design suitable for a variety of environmental and geographical conditions. HexaCore OPGW was developed in response to the demand for higher fiber counts, specifically those greater than 96.
