The 800kva transformer, with its mature and reliable technology, excellent heat dissipation performance, and flexible energy efficiency rating options, provides users with a medium to large capacity power distribution solution that balances initial investment and long term operating costs. The 3 phase power transformer's fully sealed, maintenance free structure and ONAN/ONAF dual mode cooling design enable it to adapt to diverse installation environments and load characteristics, making it a classic specification widely used in industrial and residential power distribution networks.
800kva transformer is a mainstream medium to large capacity power distribution device in the 10kV distribution network, undertaking the core function of converting 10kV (or 6kV) medium voltage electrical energy into 0.4kV low voltage user side power. Leveraging mature standardized design and large scale production, our power transformer company maintains a reasonable inventory level to support rapid delivery. We manufacture strictly according to multiple international and regional standards such as IEC, GB, JIS, ANSI, IEEE, and UL, meeting Level 1/Level 2 energy efficiency requirements. All products have passed factory testing and authoritative certifications.

High quality transformer oil is used, which has high insulation strength and good heat dissipation, ensuring long term safe operation. |
|
|
The winding is securely supported, the coil has high mechanical strength, can withstand short circuit impacts, and has no risk of deformation or displacement. |
|
|
The corrugated oil tank or fully sealed structure prevents oil and water leaks, resulting in a long maintenance free period. |
|
|
High quality cold rolled grain oriented silicon steel sheets have low loss and low noise, meeting energy efficiency and environmental protection requirements. |

1. How loud is an oil immersed transformer during operation?
Typical noise level is 55–70 dB depending on capacity and cooling method. Low noise designs are available for residential or noise sensitive areas.
2. What is the difference between ONAN and ONAF cooling?
ONAN (Oil Natural Air Natural) uses natural convection for both oil and air. ONAF (Oil Natural Air Forced) adds fans to increase cooling capacity, allowing higher output without enlarging the transformer.
3. Can I use biodegradable oil instead of mineral oil?
Yes. We offer natural ester (vegetable based) oil, which is fire resistant, biodegradable, and safer for the environment. Ideal for ecologically sensitive areas.
