Manufactured in strict compliance with the IEC 60076 international standard, the transformer, high-voltage switchgear, and low-voltage distribution equipment are integrated into a prefabricated housing.This allows for factory prefabrication and rapid on-site installation, significantly shortening the construction cycle. Suitable for distribution scenarios with 10kV incoming lines and 0.4kV outgoing lines, it is widely used in urban new district distribution networks, residential communities, and temporary power supply projects. It features a small footprint, high reliability, and easy operation and maintenance.
Professional Equipment
Target Market
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.
