3 Phases Dry Type Air Cooling Electrical Encapsulated Power Transformer 2500kVA

Our dry-type power transformers are a kind of power transformers, whose cores and windings are never immersed in mineral oil. They are widely used in shopping mall, buildings, airports, wharfs and substations for local lighting and electric energy transformation between the generator and distribution primary circuits.

Dry-type power transformers are also suitable for various switchgears applied to power system. Those up to 10kV can be installed in 650-1200 mm wide switchgears, up to 20kV in a 1000mm wide switchgears and 35kV in 1400 ~ 1600 mm wide switchgears.

1. Low no-load loss and energy conservation.

2. Low noise and environmental protection.

3. Long service lifetime and safe and reliable performance.

4. Reasonable and aesthetic structural design and exquisite manufacture craftsmanship.

5. A full variety of accessories and appropriate protection measures. 

Note: Those listed in the table above are the routine parameters for reference. Besides, products could be redesigned according to clients' actual demands. 

Guangdong Sihui Instrument Transformer Works Co., Ltd. who lies in Sihui city, the mid-west of Guangdong Province, 63km away from Guangzhou. It was founded in 1988 and has become one of the top 5 instrument transformers enterprises in China.

A series of products, such as instrument transformers, power transformers, metering trucks, insulation articles and so on, have been professionally designed, manufactured and sold. All of them are suitable for the switchgears matching, power plants and substations in those systems of  electric, railway and petrochemical industry. A great of products have owned proprietary intellectual property rights and core technology. Meanwhile, about 30 national honors have been won.

Our products have been sold well everywhere domestically as well as exported to Europe, America, Russia and Asia, which brings high reputation both at home and abroad. What's more, they are extraordinarily applied to power-supply systems of national key infrastructures, such as Guangzhou Baiyun International Airport, Guangzhou Metro, Shanghai Pudong Airport, Zhongnanhai, Beijing Olympic Game Venues, Jiuquan Satellite Shoot Centre, etc.
