Overview
The energy-efficiency grade 1 oil-immersed transformer is an energy-saving product designed to the grade 1 requirements of GB 20052-2020 and developed by Jiangsu Xinhong. Through the application of new materials and new processes, the core and winding structure has been optimised and redesigned to reduce no-load loss and noise.
The noise level is on average 20% below the limits of the industry standard JB/T 10088-2016. Grade 1 products have lower losses than energy-efficiency grade 2 products.
Applications
- Utility distribution networks
- Residential districts
- Industrial plants
- Commercial and public buildings
- Continuously loaded substations
- Box-type substations (KTP)
