The company introduces advanced European technology and optimizes the design of epoxy resin cast dry-type transformers through patented technology and specialized software. The product uses high-quality grain-oriented cold-rolled silicon steel sheets as the core, manufactured by German GEORG company's automatic core production line with longitudinal and transverse shearing, adopting new stacking processes that greatly improve the no-load performance of the core. The coils use American Premier epoxy resin, and the epoxy resin casting process is completed by German HEDRICH vacuum casting equipment. The product has good resin penetration, no air gaps, and thus low partial discharge. The high and low voltage coils are tightly matched with extremely strong mechanical strength, ensuring high short-circuit resistance and shock resistance. Under normal use conditions, the product has a service life of 30 years, and within the operating life, normal use conditions will not cause surface cracking of the coils due to temperature changes.
