Product Overview
  1. Ultra-Low Loss Performance: The combination of amorphous alloy cores and optimized winding structures results in no-load loss that is only 60%-70% of that of standard S13-series transformers. This not only cuts down on operational energy costs but also reduces carbon emissions, aligning with green development objectives.
  2. Enhanced Environmental Compatibility: The optional eco-friendly insulating oil and leak-proof design minimize the risk of soil or water pollution, making the transformer suitable for environmentally sensitive areas (e.g., near water sources or ecological reserves). Additionally, the product’s long service life (typically 25-30 years) reduces the frequency of equipment replacement, lowering overall resource consumption.
  3. Intelligent Operation Readiness: The built-in intelligent monitoring modules enable seamless integration with smart grid systems. This allows for real-time data analysis, fault early warning, and remote parameter adjustment, reducing manual maintenance workload and improving the reliability of power supply.
  4. Policy Support Eligibility: Many models of this transformer qualify for national or local energy-saving subsidies and green procurement programs. This provides financial incentives for users, shortening the return on investment period and enhancing the product’s cost competitiveness.

Company Profile

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.
