Rolled Iron Core Transformer
Product Characteristics
This series of power transformers is a new generation of high-tech, high-performance and energy-saving products that are at the international advanced level of similar products. The transformer core material is made of high magnetic permeability oriented cold-rolled silicon steel sheet wound into a enclosed shape, and there is no butt seam in the silicon steel sheet, and the core is annealed after being rolled. The transformer adopts a fully-sealed structure, and the oil conservator is cancelled. Since the contact between the oil and the air is isolated, the insulation is not easily affected by moisture, the aging degree is greatly reduced, and the reliability and service life of the transformer are greatly improved.
