Oil-Immersed Transformers
Liquid-cooled transformer options for utility and industrial power systems.
ILLUSTRATIVE PRODUCT IMAGEWhat is an oil-immersed transformer?
An oil-immersed transformer uses insulating liquid as part of its insulation and cooling system. This product family is commonly considered for utility networks, substations and industrial power distribution. The appropriate construction depends on the duty, installation environment and technical standard.
Where is it considered?
Applications can include transmission and distribution substations, generation connections and large facility supply. Capacity, voltage ratio, cooling arrangement, loss targets and protection requirements should be established before a configuration is proposed.
What to include in an inquiry
- Rated capacity, primary and secondary voltage, frequency and phases.
- Required impedance, loss values and cooling or temperature-rise criteria.
- Outdoor or indoor location, climate, altitude and applicable standards.
- Required accessories, monitoring, drawings, tests and destination.
