* Above specification may be changed to improve performance.
* Transformer of other specification than listed above can be made to order.
Customized for medium power demand, with a voltage adaptation range of 10-30kV and a power range of 250-630kVA. The winding insulation and heat dissipation structure have been upgraded, adopting class 130 oil-resistant insulating materials and chip-type radiators, which enhances short-circuit resistance and heat dissipation efficiency, enabling it to cope with medium load impacts such as the startup of industrial equipment. It is suitable for medium-load scenarios including industrial park branch power distribution, large-scale community power supply, and agricultural irrigation pump stations.

Guanggao Transformer is a professional transformer manufacturer. We produce single-phase, three-phase, dry-type, distribution, and high-voltage transformers (110 kV and above). We meet IEEE/ANSI/UL/CSA and IEC standards. Guanggao Transformer has nearly 25 years of transformer export experience. The company has modern laboratory construction, such as high-voltage test hall, within which there is a 3000kV lightning impulse testing device, and some advanced testing equipment, such as CA-21 moisture analyzer from Mitsubishi, American Fluke Ti30 infrared image detector, American RM-3WE three dimensional vibration. And it was identified as the national power transformer energy efficiency testing laboratories in 2011.
The company has undertaken the National Olympic Security Power Project, the National 851 project, the whole construction of the Guangzhou Asian Games, Guangzhou BRT and other important security power projects. The products used in the above projects are highly safe and in a reliable operation throughout the country. Also, these products are exported to Myanmar, Madagascar, Malaysia,other countries. Enjoying a good reputation on the electromechanical market, "Guanggao Brand"was identified as Guangdong famous brand, the product was identified as the National Energy Efficiency Star Products and Brand-Name Products in Guangdong Province.If you have transformer needs, please contact us.
