Aerial Covered Conductor Systems in Inclement Weather and Harsh Environments

Aerial power delivery systems around the world are usually constructed with bare wire, and rightly so, as bare wire systems have the lowest installed cost, and are relatively easy to maintain. There are numerous applications which place additional requirements on power systems, however, such as the need to improve reliability, co-exist with trees, build multiple circuits or long spans, traverse narrow right-of-ways, or provide resilience in the face of harsh weather. The harsh weather considered is usually high winds, snow, and ice, as well as hurricanes.

This presentation will explore the challenges of designing aerial systems in harsh weather environments, and how covered conductor systems, both Spacer Cable as well as Tree Wire, may provide solutions, where other options are either less reliable, more costly, or both.

 

Attendees will:

• Be shown what the concerns are for aerial power lines in harsh weather environments (wind, ice, snow, hurricanes, etc.)

• Learn how spacer cable systems can provide system hardening in the face of extreme weather.

• Get an understanding on how covered conductor systems (both spacer cable as well as tree wire systems) perform compared to each other, as well as how they perform compared to bare wire systems.
