Double circuit: Two transmission lines on the same transmission structure, with each single circuit made up of three sets of conductors.

Duct bank: A reinforced pathway for transmission cables to be safely buried underground.

Maintenance hole: Used as an entrance point for our utilities, a maintenance hole provides a cable splice location and utility crews the ability to access and maintain our underground infrastructure.

Single circuit: A single transmission line on one structure, with each single circuit made up of three sets of conductors.
