ODM CRGO Steel Strips For Magnetic E And I Core Transformer
Electrical steel is classified into two types: Non-oriented (NO) electrical steel and Grain-oriented (GO) electrical steel. NO steel is widely used in motors and generators, in which the magnetization direction is rotated in the sheet plane. GO is mainly used as a core material of transformers, in which the magnetization direction is unidirectional.
Grain-Oriented Electrical Steel is an electrical steel in which the easy magnetization direction of the grain is parallel to the rolling direction and the silicon content is about 3%.
●Exhibits excellent magnetic properties in one direction (the rolling direction) of the steel sheet
●Features excellent magnetic properties, including high magnetic flux density, low iron loss, and low magnetostriction
●Typical applications: power transformers, distribution transformers, audio transformers, current and potential transformers, medium to large generators, reactors, and magnetic shields.

| Notes: a. The traverse thickness deviation refers to the thickness difference between the center of the steel plate and 15mm from the edge. b. The longitudinal thickness difference is the difference between the maximum thickness and the minimum thickness measured along the length direction (parallel to the rolling direction) on any steel strip with a length of 2m. c.
