Engineered for heavy-duty power distribution, the 3 MVA 11kV Oil Cooled Distribution Transformer stands out as a robust solution for managing high-volume electrical loads. With a rated capacity of 3 MVA (equal to 3000 kVA) and an operating voltage of 11kV (11,000 volts), it’s tailored to meet the demands of large-scale power transmission and distribution networks.
At its core, an efficient oil cooling mechanism ensures optimal thermal management: the specialized cooling oil circulates to dissipate heat from the transformer’s windings and core, a key design choice that mitigates the risk of overheating—one of the leading causes of equipment breakdowns or unexpected downtime.
Beyond temperature control, the insulating oil serves a dual purpose as a reliable electrical insulator. It forms a protective layer that inhibits arcing between windings, safeguarding against short circuits and enhancing the transformer’s operational safety and long-term durability.
Ideal for scenarios requiring stable, high-capacity power handling, this transformer balances performance and reliability, making it a trusted choice for industrial facilities, utility grids, and large commercial complexes.
