Question 1

What voltage levels are available for this transformer?

Accepted Answer

This transformer series is available in three voltage levels: 10kV (30-2500kVA), 20kV (30-2500kVA), and 30kV (30-1600kVA). The voltage level selection depends on your distribution network requirements and local grid standards.

Question 2

What is the difference between IEC and GB standards?

Accepted Answer

IEC (International Electrotechnical Commission) standards are international guidelines, while GB (Guobiao) standards are Chinese national standards. Our transformers comply with both IEC 60076 series and GB/T 1094 standards, ensuring compatibility with both international and Chinese power systems.

Question 3

How does oil-immersed cooling compare to dry-type transformers?

Accepted Answer

Oil-immersed transformers offer superior cooling efficiency, higher capacity range (up to 2500kVA), better overload capacity, and longer service life compared to dry-type transformers. They are ideal for outdoor installations and high-capacity applications.

Question 4

What maintenance is required for oil-immersed transformers?

Accepted Answer

Regular maintenance includes annual oil testing for dielectric strength, routine inspections for oil leaks and component wear, load monitoring to prevent overloading, and periodic cleaning to maintain cooling efficiency. Our transformers are designed for easy maintenance with accessible inspection points.

Question 5

Can this transformer be used for both pad-mounted and pole-mounted installations?

Accepted Answer

Yes, this transformer series is versatile and can be configured for both pad-mounted (ground installation) and pole-mounted (overhead installation) applications. The mounting configuration is specified during ordering based on your installation requirements.

Question 6

What is the typical lifespan of these transformers?

Accepted Answer

With proper maintenance, our oil-immersed transformers have a typical service life of 25-30 years. The high-quality insulation materials and robust construction ensure long-term reliability even in harsh environmental conditions.

Question 7

Are these transformers suitable for renewable energy applications?

Accepted Answer

Absolutely. These transformers are widely used in renewable energy installations including solar farms and wind power stations. They handle voltage fluctuations well and provide stable power conversion for grid integration.

Question 8

What certifications do these transformers have?

Accepted Answer

Our transformers are fully certified to IEC 60076 series, IEC 60135, IEC 60214-1, GB/T 1094, GB/T 6451, and GB/T 7597 standards. They also hold UL/CSA certifications for international markets, ensuring compliance with global safety and performance requirements.
