Product Introduction
The oil-cooled transformer is a reliable medium-voltage power equipment designed to transfer electrical energy efficiently by stepping down 11kV primary voltage to lower levels (e.g., 415V) for industrial, commercial, and utility grids. Utilizing insulating oil as both a coolant and insulator, it employs natural oil circulation (ONAN cooling) to dissipate heat from its low-loss silicon steel core and copper windings, ensuring stable operation under loads up to thousands of kVA. Housed in a robust steel tank, it features hermetic seals or breather systems to prevent moisture ingress, along with safety components like pressure relief valves and oil level gauges. Ideal for outdoor or indoor installations in environments requiring high durability-such as factories, substations, or rural areas-it offers advantages like high insulation strength, low noise (≤55dB), and long service life (20+ years) with minimal maintenance. Compliant with international standards (e.g., IEC 60076), this oil cool transformer balances cost-effectiveness and performance, making it a core component in medium-voltage power distribution networks.
