Our History

1908
The Beginning
1908
Delta Star was originally founded in Chicago as the Delta-Star Electric Company manufacturing electrical devices in the generation, transmission, and distribution sectors. Early products included a line of high-voltage indoor and outdoor switches including disconnects, transfers, interrupters and disrupters for single and group operation.
1935
Advances In Technology
1935
The company’s fame for improvement and development of substations spread to the federal government when in 1935 Delta-Star Electric was contracted by the government to produce what was considered at that time, the largest disconnecting switches ever built. In the same year, the Hoover Dam contractors solicited Delta-Star Electric’s help to manufacture a disconnecting switch able to handle 286,000 volts. These were the largest air-break switches ever made, weighing 15 tons each. The company made continued technological advances between the years of 1913 and 1950, patenting over 87 inventions.
