27Q100 Hi-B Oriented Silicon Steel – Engineered for Power Transformer Cores
URL Slug: 27q100-hi-b-power-transformer-core
Product Summary
27Q100 is a high magnetic induction grain-oriented silicon steel (Hi-B) from our electrical steel portfolio. With a thickness of 0.27mm, it delivers a maximum iron loss of 1.00 W/kg (P1.7/50) and a minimum magnetic flux density of 1.91T (B8). Designed for power transformers, reactors, and electrical equipment cores, it combines efficiency and reliability for demanding grid applications.
Key Selling Points
- Ultra-low iron loss (≤1.00 W/kg): Reduces no-load losses in transformer cores, lowering operating costs and improving energy efficiency.
- High magnetic flux density (≥1.91T): Enables compact core designs, reducing material usage and transformer size.
- Precise thickness (0.27mm): Optimizes lamination factor and reduces eddy current losses for stable performance.
- Proven in global applications: Used by transformer manufacturers serving markets in Mexico, Brazil, and Europe, with stable operation over 10 years.
- Reliable supply chain: Backed by 30,000m² processing plant and annual output of 30,000 tons.
