Product Q&A
Q:What are the main advantages of oil-immersed transformers compared to dry-type?
A:
Oil-immersed transformers offer better heat dissipation, stronger insulation performance, and are generally more cost-effective for outdoor installations and harsh environments.
Q:Can this 250kVA transformer be used in residential areas?
A:
Yes. It is ideal for residential power distribution, providing stable 0.4kV output with low noise levels and high safety standards for urban and rural grids.
Q:Does your transformer support Dyn11 vector group connections?
A:
Absolutely. While our standard is often Yyn0, we can customize the vector group to Dyn11 to improve unbalanced load capacity and harmonic suppression as per your project needs.
Q:How do you ensure the quality of the transformer oil?
A:
We use high-quality mineral insulating oil with excellent dielectric strength. Our fully sealed corrugated tank prevents air and moisture contact, maintaining oil purity for life.
Q:What certifications do your transformers hold for international markets?
A:
Our products are manufactured according to IEC60076 standards and hold CE and ISO9001 certifications, ensuring compliance with global electrical safety and quality requirements.
