Applications
Grain-oriented silicon steel strip is primarily used in the manufacture of transformer cores. Due to its low iron loss and high magnetic flux density, it significantly improves transformer efficiency and reduces energy consumption. Specific application scenarios include:

Transformer Manufacturing: Mainly used in main transformers and distribution network transformers, reducing power transmission losses by minimizing core losses.

Ultra-high voltage transformers using high-end grain-oriented silicon steel can reduce size and noise while decreasing core losses by approximately 8%.

New Energy Sector: Used in wind power and photovoltaic projects to reduce energy losses during renewable energy integration.

Demand for high-end non-grain-oriented silicon steel is growing significantly in electric vehicle drive motors.

Other Industrial Equipment: Large motors (such as industrial generators and electric motors), reactors, voltage regulators, and other equipment rely on its high magnetic permeability.
