Design
Using advanced electromagnetic design optimization software to enhance the precision and speed of designing amorphous alloy dry-type transformers, achieving design automation and optimization. With powerful simulation capabilities, each product series undergoes simulation analysis for the flow field, temperature field, leakage field, short-circuit force, etc., ensuring product safety and reliability.
Iron Core
Made with high-quality amorphous strip materials in a three-phase three-column configuration, undergoes annealing under DC field intensity to achieve excellent characteristics of low iron loss and low excitation current. The surface of the iron core is coated with a special resin to prevent moisture and corrosion. The iron core has a simple structure, high mechanical strength, and is resistant to high-order harmonics, with iron loss 70% to 80% lower than conventional products.
