Product Q&A

Q:What are the main application scenarios?

It is suitable for power systems with AC 50Hz and rated voltage up to 33kV, particularly in heavy dust environments like petroleum, metallurgy, and chemical industries.

Q:How is the transformer cooled?

It uses an oil-immersed cooling method with a fully sealed tank featuring corrugated walls that act as heat sinks and allow for 'breathing' to compensate for oil volume changes.

Q:What certifications does the product have?

The product holds ISO9001 and CCC certifications, ensuring compliance with quality and safety standards.

Q:What is the warranty or maintenance requirement for the oil?

Due to the vacuum oil injection process which prevents moisture and oxygen invasion, regular oil sample tests are not necessary.

Q:Can the voltage taps be adjusted?

Yes, the high voltage winding has taps connected to a tap changer on the box cover, allowing voltage changes after the power supply is cut off.
