The suffix "NX3" serves as a scenario-specific optimization for rural/suburban use cases: on one hand, it may integrate a reinforced oil tank structure (enhancing resistance to accidental impacts in open-air installation environments); on the other hand, it could feature a simplified maintenance interface (reducing the need for professional service teams, which are often scarce in remote areas). Matched with "Energy Efficiency Level 3", this model meets national basic energy efficiency standards while avoiding the high manufacturing costs of top-tier efficiency variants. Its oil-immersed structure, a departure from dry-type designs, offers superior heat dissipation for prolonged operation and better tolerance to temperature fluctuations—critical for rural areas with inconsistent climate control. For power grids where transformers spend long hours in no-load mode (e.g., nighttime standby for agricultural irrigation systems), the amorphous alloy core’s low-loss advantage not only slashes annual electricity expenses but also reduces heat generation, extending the service life of internal components and lowering long-term replacement costs.
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.
