138kV Energized Structure Replacement

138kV Energized Structure Replacement

Client: Enmax

Owner: Enmax

Project Status: Completed 2009

Location: Calgary, Alberta

Voltage: 138kV

Category: Energized services

The project:

Enmax required that three 138kV double circuit structures be relocated and conductors had to be raised to enable construction of a Rapid Transit System.

The Challenges:

Due to Utility system requirements, the circuits needed to remain energized during the execution of the work. The work was done in a congested city environment.

 Specialized Work Methods:

Allteck utilized 30402 and 9201 Robotic Arms to move the energized conductors. Multiple Barehand procedures were also required to both remove and install structures and to terminate conductors.
