A 20000kVA power transformer is a three phase power transformer that uses mineral insulating oil as the insulation and cooling medium. It has a rated frequency of 50Hz and is suitable for voltage level transformation and power transmission in power systems. This type of transformer is one of the core pieces of equipment in the power supply systems of factories, mines, industrial buildings, power plants, and substations. It can transform 10kV, 35kV, 66kV, or 110kV network voltages to the bus voltage required by the user side, meeting the power needs of different power equipment.
The 20000kVA power transformer has outstanding insulation performance and strong weather resistance, adapting to complex outdoor environments and effectively resisting external influences such as humidity and corrosion, extending the service life of the equipment. It can meet the power demand of ultra large scale and ultra high loads, providing safe, continuous, and efficient power support for various scenarios, contributing to the efficient operation of the power grid and the rational utilization of energy. It is the core preferred equipment in ultra large capacity power distribution scenarios.
- Fully sealed structure, leak proof, maintenance free, and ensures stable and reliable long term operation.
- Oil immersed insulation and heat dissipation provide strong overload capacity and adaptability to harsh outdoor environments.
- Low loss and high efficiency significantly reduce operating energy consumption and operating costs.
- Compact structure, small footprint, easy installation, and strong adaptability.
- High cost effectiveness, long service life, and lower overall operation and maintenance costs.
- Short circuit resistant and impact resistant, meeting the requirements for long term continuous load operation.

1. What is the difference between oil immersed and dry type transformers?
Oil immersed uses mineral oil for cooling and insulation. It costs less, handles higher overloads, and lasts longer outdoors. Dry type is maintenance‑free and fire‑safe indoors.
2. Where can I install an oil immersed transformer? Do I need fire protection?
Typically outdoors – substations, industrial plants, solar farms. Indoors requires a fire‑rated vault or oil containment pit due to flammability.
3. What maintenance does an oil immersed transformer require?
Periodic oil testing (dielectric strength, moisture, dissolved gases), filter regeneration, and inspection of bushings, gaskets, and cooling fans. With proper care, service life exceeds 30 years.
