Three phase pad mounted transformers/

11kV 15kV 20kV 22kV 30kV 33kV substation

Rockwell transformer Co.,Ltd. offer an environmentally responsible, high efficiency, safer choice. The units have high-fire-point fluid, providing fire safety benefits, and a projected life well beyond that of a traditional mineral-oil transformer. These efficient and cost-effective transformers use Envirotemp™ FR3™ fluid. Envirotran transformers are manufactured in 50 - 10,000kVA, in primary voltage classes of 11kV,15 kV, 25 kV and 35 kV.

kVA

50-20,000

Primary Voltage

Up to 34,500 V

Secondary Voltage

208-14,400 V

Three-phase, pad-mounted transformers, for use on underground power distribution systems, are best suited for commercial applications in public access areas and where underground service is required. These transformers meet modern design requirements for flexibility and provide a visually pleasing installation. Construction allows installation in locations accessible to the general public without the need for protective fencing or vaults. These units are ideally suited for apartment buildings, schools, hospitals, shopping centers, commercial buildings, or industrial sites.
