Made of high magnetic-flux, low iron-loss silicon steel sheets, wound in varying widths creating steps. Produced using advanced technologies: high vacuum annealing, vacuum immersing, and baking paint on within a protective atmosphere. This type of core has single-phase and three-phase points. Compared to laminated iron cores, Step Wound Cores are smaller, have lower air cut losses, lower low to no-load losses, create less noise, and so on, giving these cores greater advantages in small to medium-sized distribution transformers.
Applications: ?Distribution Transformers ?/ ?Power Transformers ?/ ?Transformers ?/
Reactors ?/ Voltage Regulators ?/ ?Special Transformers ?/ etc.
