Los Angeles Department of Water and Power Transmission Line
Backstory and Context
This line is the Barren Ridge- Haskell Canyon, double-circuit electrical transmission line. Known as the BAR-HSK, line, it connects the Barren Ridge and Haskell Canyon Switching Stations. The Barren Ridge Switching Station is located south of Angeles National Forest and about 12 miles north of Mojave. In 2011, about 60 miles of new, double-circuit, 230 kilivolt transmission line were completed. At the same time, the Barren Ridge Switching Station was expanded and the Haskell Switching Station, in Santa Clarita was replaced.This electric transmission line travels north-south and intersects Highway 138 at 120th Street. Three braced steel towers are located in this segment of the transmission line. Each tower consists of steel construction set on four concrete bases or “stubs.” Each tower has three cross arms atop the “cages” which support phase conductors or insulators on each side. The trio of cross arms make this a three-circuit system. The insulators each support paired conductor wires. Two sets of electrical grounding wires are strung across the peaks of each tower.
