Oracle-Tucson Pole Replacement
CX(s) Applied: B4.6

Office(s): Western Area Power Administration-Desert Southwest Region

Western plans to replace deteriorated wood poles, cross arms and X-braces at two existing H-frame structures located along the Oracle Tucson 115-kilovolt Transmission Line in Pima, Arizona. Built in 1943, its aging components are beyond repair and require replacement. These poles performed poorly during structural tests, and we consider them unstable. This replacement project will ensure the safety of Western's workers and the public as well as reliability of the bulk electric system.
