Meet Our Team

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.
Advances In Technology
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.
Delta-Star Electric Company is purchased by H. K. Porter Company and subsequently renamed the Delta-Star Electric Division of H. K. Porter Company. Locations were then added in Belmont, California and Lynchburg, Virginia.
The First Mobile
Delta Star successfully deploys its first mobile power transformer to Withlacoochee River Electric Cooperative, Inc. Since this time, the company has manufactured and deployed more than 800 mobile substations and mobile power transformers throughout North America.
Delta Star separates from H.K. Porter Company and becomes an Employee Stock Ownership Plan (ESOP).
Celebrating a Milestone
Delta Star, Inc. celebrates 100 years in the electrical industry as a world-class manufacturer of medium-sized transformers and a wonderful force in the community.
Delta Star expanded its capabilities and introduced Field Service as a standalone division, offering full-service packages to minimize future unscheduled maintenance and optimize the life of the transformer.
Delta Star acquires a transformer factory located in Saint-Jean-sur-Richelieu near Montreal, Quebec. The plant, formerly owned by Alstom, provides Delta Star’s customers with a third location to build power transformers.
Delta Star Field Service celebrates 10 years of transformer service to utility, cooperative, and municipal customers across North America.
