A fire at a Southern California Edison substation in Acton burned several hours Friday, fueled by thousands of gallons of mineral oil used to insulate transformers.
An internal mechanical failure sparked the blaze about 6:30 p.m. at the manned substation, said Edison spokesman Steve Conroy.
Flames were visible 10 miles away in Palmdale. County Fire Capt. Mark Savage said about 75 firefighters used foam to quell the blaze near Angeles Forest Highway and Hillside Drive. No injuries were reported.
Conroy said the facility is a major substation carrying electricity to Los Angeles, but no outages occurred.
