Substation & Distribution Replacement

Substation & Distribution Replacement

Location: Fort Worth, Texas

Client: Lockheed Martin

The Air Force Plant 4 substation equipment and 5-kV distribution feeder cables are nearing the end of their useful life. Burns & McDonnell estimated life-cycle cost for multiple replacement and upgrade options. Transmission service with a phased design and installation proved to be the most economic and reliable option, with Lockheed constructing a new substation adjacent to the existing one. The existing radial 5-kV distribution system will be replaced with a looped system to improve reliability and maintainability. Multiple radial feeders will be combined and connected to new feeder loops served from new substation switchgear.
