FAQ

Here are some questions and answers you may want to know when you buy 20kV oil-immersed transformer.

Q: What kind of 20kV transformer do you have?

A: We have an array of 20kV transformers, from oil-immersed transformers with off load tap changing to on load tap changing. The 20kV distribution market can be tailored for energy efficiency ratings.

Q: Is it possible to tailor a transformer to suit my particular needs?

A: Yeah, sure. Our speciality is in providing customised solutions. You can choose many parameters such as power rating, input/output voltage, frequency (50 Hz/60 Hz), insulation class, cooling method and applicable standards (IEC, ANSI, IEEE, etc.). Our technical team will review and verify the feasibility of these solutions.

Q: What international standards do your transformers comply with?

A: Our transformers are mainly based on IEC 60076. We can also supply products to other regional standards as required including ANSI/IEEE, CSA, EN and DOE energy efficiency standards. Enquires should specify what certification standards are desired.

Q. What is the normal voltage and frequency?

A: Our transformers meet international standards (e.g. 20 kV, 22 kV, 33 kV) and the applicable frequency standards (50 Hz or 60 Hz). We also offer customised products to meet the needs of specific markets.

Q: How do I ask for a quote?

A: Send us an email or use our "Contact Us" form, tell us your requirements, order quantity and destination port. The more specific the information you give the more accurate our quote will be.
