FAQ about Electrical Transformer

Part of the heat comes from the copper windings themselves. Another part arises from hysteresis and eddy current losses in the silicon steel core sheets caused by the alternating magnetic field. These factors lead to a rise in temperature.

To get suitable recommendations or accurate quotes, provide the following information.

Transformer application (such as industrial, solar, wind farm, data center, substation, or power distribution)

Rated capacity (kVA/MVA)

Primary and secondary voltage

Phase (single phase or three phase)

Frequency (50Hz or 60Hz)

Installation environment (indoor/outdoor, climate conditions, etc.)

Required standards or special requirements

If you already have technical specifications, please send us the transformer datasheet. If you are not sure about the exact requirements, simply tell us your project application and power needs. Our engineering team can help select and customize the suitable transformer solution for your project.

Yes, we are professional manufacturer of the transformer with design team. Additionally, we can provide you with a detailed list of accessories during the early stages of your project preparation. Anyway, our design team will escort your customization.

Before delivery, every transformer undergoes strict factory testing to ensure reliable performance and safe operation. All tests are performed according to international standards such as IEC 60076.

The main tests include:Winding resistance test, voltage ratio test, insulation resistance test, no-load loss test, load loss test, and dielectric tests.

If you need to conduct a type test on the transformer, we can arrange for you to contact the relevant laboratory.

Additional tests such as partial discharge test, noise level test, and special performance tests can be provided based on customer requirements.

After completing the tests, we provide test reports and technical documents to verify transformer quality before shipment.

Our products can comply with standards including:

IEC 60076 – International standard for power transformers

IEEE / ANSI standards – Commonly required for North American power projects

ISO quality management standards – Ensuring consistent manufacturing and quality control

For different countries and projects, we can provide the required technical documents, test reports, and certification documents according to customer specifications.

Choosing the appropriate transformer takes more than just choosing from a selection of types. There are a number of technical and commercial factors engineers need to consider when moving forward.

A suitable transformer should match:

Electrical requirements

Installation environment

Load characteristics

Safety standards

Maintenance expectations
