Main Features

1. Low no-load loss and noise. The performance indicators of our company's 220kV and above power transformers meet or exceed the national standard, and the noise is much lower than the national standard.

2. Safe and reliable operation. Transformers can operate stably under long-term working voltage and short-term overvoltage.

3. Easy installation and maintenance:

During on-site installation of transformers, there is no need to inspect the hanging cover, and all accessories are pre installed in the factory.

The transformers all adopt natural oil circulation cooling method, which still has more than 70% cooling capacity when the fan stops working, and the cooling system requires almost no maintenance.

The transformer adopts a maintenance free structure and process, making product maintenance simple and convenient.

4. Exquisite craftsmanship. The appearance of the oil filled transformer is clean, leak free, and aesthetically pleasing.
