Dry-Type Transformers
Grade 1 Energy-Efficient Dry-Type Transformer
Also known as: Grade 1 Dry-Type Transformer; High-Efficiency Cast Resin Transformer
Boreviax supplies high-efficiency dry-type transformers designed for applications requiring reduced electrical losses, reliable operation, and enhanced fire safety. Available configurations can be designed to meet Grade 1 energy-efficiency requirements under GB 20052-2024 for applicable ratings.
Final voltage, capacity, losses, impedance, accessories, dimensions and applicable standards are confirmed according to the project specification and quotation.
Product overview
Design and operating characteristics
The transformer uses an optimized magnetic core and winding structure to reduce no-load and load losses while maintaining low operating noise and stable temperature performance. Its cast-resin insulation system provides strong mechanical strength, good short-circuit withstand capability, low partial discharge, and reliable long-term operation.
An intelligent temperature monitoring system continuously measures the temperature of each phase winding. Depending on the selected configuration, the system can automatically control cooling fans and provide over-temperature alarm and trip signals.
Grade 1 refers to the applicable Chinese energy-efficiency classification under GB 20052-2024. It is not presented as equivalent to EU, Canadian or U.S. efficiency classifications.
