Ultra-High Voltage Hi-B Oriented Silicon Steel 18-65
High magnetic induction grain-oriented silicon steel for ultra-high-voltage transformers
This Hi-B oriented silicon steel is engineered for ultra-high-voltage and power transformer cores. With a thickness of 0.18mm and iron loss ≤0.65 W/kg, it ensures high efficiency in energy transmission. Its high magnetic flux density (B8 ≥1.88T) and strictly controlled impurities make it ideal for demanding grid applications.
Key Selling Points
Ultra-Low Iron Loss
Iron loss ≤ 0.65 W/kg (P1.7/50) reduces core losses, improving transformer efficiency and lowering operating costs over the long term.
High Magnetic Flux Density
Magnetic flux density B8 ≥ 1.88T allows for smaller core dimensions and lighter transformer designs, saving material and space.
Precise Thickness Control
Thickness of 0.18mm ensures consistent magnetic properties and lamination factors, crucial for high-performance transformer cores.
Controlled Impurities
Strict control of impurities like C, S, and N ensures high magnetic permeability and stable performance, meeting the needs of Hi-B steel applications.
Proven Reliability
In use for over 10 years in global transformer manufacturing, with stable operation verified in the field.
Global Supply Capability
Annual output of 30,000T and 80% export ratio ensure reliable supply for international transformer manufacturers.
