General Questions
Our transformers are widely used in: Data centers, Semiconductor plants, Pulp and paper mills, Metallurgy, Petrochemical industries.
We have two manufacturing bases in China:
Nanjing: Dry-type transformers
Zhenjiang: Oil-immersed transformers
Our transformers support up to 35kV rated voltage.
Our transformer products comply with international standards such as IEC 60076 and IEEE C57.12.60 . Additionally, our company participated in the development of the National Standard of China "Assessment Criteria for Energy Efficiency of Building Electrical Systems."
Our transformer products have obtained multiple authoritative international certifications, such as UL, CE, and ASTA certifications.
Product Questions
34.5kV/13.8kV: Dry-type – 25,000 kVA, Oil-immersed – 31,500 kVA
34.5kV/690V: Dry-type – 4,000 kVA, Oil-immersed – 5,500 kVA
Dry-type: 25,000 kVA; Oil-immersed: 31,500 kVA.
Efficiency is generally between 98.5% and 99.3% (per IEC60076-20). Higher efficiency means better materials (e.g., silicon steel, copper) and higher cost.
Dry-type: Up to 30 years, maintenance-free. Oil-immersed: Also 30 years, but recommended maintenance every 2 years.
Yes. We can customize multi-tap transformers for dual voltages (e.g., 13.8/12.47kV), and multi-winding designs for PV and ESS systems. Production lead time will be extended by 15 days.
Sales Questions
Our company has extensive and diverse successful project experience in the international market. Our transformer products have been widely used in multiple countries and regions around the world, covering important markets such as North America, South America, Southeast Asia, the Middle East and Africa. We have the ability to provide customized solutions for different grid standards, harsh environmental requirements and high-end industry applications. Here are some representative international project cases of ours:
