Product Overview
Core Role in Regional Energy Security
The 2200kV 320MVA oil-immersed power transformer functions as a "critical link" in regional power grids, underpinning the stability of energy supply for key areas. Rated for 110kV voltage operation, its 320MVA capacity is specifically tailored to meet the high-demand power needs of energy-critical scenarios: large industrial and mining complexes (sustaining continuous production that relies on uninterrupted electricity), urban core districts (supporting essential services like transportation, healthcare, and commerce), and new energy integration hubs (managing the variable output of wind and solar farms to avoid supply gaps). Beyond standard transmission, transformation, and distribution tasks, it acts as a buffer against grid fluctuations—ensuring energy supply resilience even during peak load periods or temporary disruptions.
Guanggao Transformer is a professional transformer manufacturer. We produce single-phase, three-phase, dry-type, distribution, and high-voltage transers (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 impulsforme 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.
