Description

EI transformer core factory price electrical steel silicon sheet

Processing Properties

The product is suitable for punching and cutting with excellent dimensional tolerance.

Insulation Coating

The insulation coating has small color deviation, good adhesiveness and excellent resistance to heating and corrosion with high insulation coating resistance. There are several types of insulation coating available for production. According to the test results performed by the professional inspection organizations, the contents of hazardous substances comply with all the prevailing international and domestic environment protection laws and regulations including EU RoHS and REACH regulations.

Core punching material

The punching material of the core of the hydroelectric generator is usually silicon steel. Silicon steel sheet is a thin steel plate with very low carbon content. In order to obtain feasible low hysteresis loss. Production under special control conditions. Generally, pure iron is not suitable for alternating magnetic fields, mainly because its small resistivity causes large eddy current losses.

After adding silicon element, silicon and iron form a solid solution alloy, thus increasing the resistivity. Silicon steel sheet is to increase the resistivity to reduce the eddy current loss caused by the thickness direction. Eddy current loss is proportional to the thickness of the silicon steel sheet, usually the thickness of the silicon steel sheet for the core is 0.35 ~ 0.5mm.

The silicon steel sheet used in the motor is divided into cold rolling and hot rolling. Cold-rolled silicon steel sheet is divided into two types, oriented and non-oriented. Oriented silicon steel sheet is anisotropic. When the magnetic flux direction is parallel to the rolling direction, its unit loss is particularly low. Therefore, it is an ideal material for transformer cores, but it is used in generators.

Its scope is extremely limited. The non-oriented silicon steel sheet is isotropic and is rolled by a method similar to the anisotropic silicon steel sheet. Compared with the oriented silicon steel sheet in terms of rolling quality and electrical performance, it is superior. Therefore, it has become common practice to use isotropic cold-rolled silicon steel sheets on the stator core punches of large hydroelectric generators. For the silicon steel sheet grade and performance of e799bee5baa6e4b893e5b19e31333431366261 used by the generator, please refer to the relevant specifications or standards.
