Premium Silicon Steel Transformer Core
The high-precision transformer cores are engineered specifically for high-efficiency power equipment. Utilizing premium silicon steel sourced from leading domestic manufacturers—such as Baosteel and WISCO—and integrating proprietary intelligent material-optimization algorithms with fully automated slitting and cut-to-length machinery, the manufacturing process strictly limits processing burrs to ≤0.02mm. The laminations feature a precise thickness range of 0.20-0.35mm, achieving a stacking factor as high as 0.97. Furthermore, by employing dedicated intelligent equipment for no-load loss testing, we ensure—right from the source—exceptionally low no-load losses and highly accurate test data, making these cores the premier choice for high-quality transformers.
Description
Product Advantages
1.Premium-Grade Raw Materials: We source silicon steel sheets directly from leading manufacturers—such as Baosteel, Wusteel, and Shougang—thereby guaranteeing superior magnetic permeability and minimizing iron loss right from the source.
2.Ultra-High Processing Precision: Processed using fully automated CNC shearing equipment, our components feature burrs of ≤0.02mm and a sheet thickness tolerance refined to within 0.20–0.35mm. This effectively prevents inter-sheet short circuits and substantially reduces eddy current losses.
3.Intelligent Material Optimization & Low Loss: Our proprietary nesting and material calculation system—combined with an exceptionally high stacking factor of 0.97—creates a more compact magnetic circuit, significantly reducing no-load losses and operational noise. Rigorous Factory Testing: Equipped with specialized intelligent no-load testers, we ensure that all factory-verified data is precise, reliable, and fully trustworthy.
Application Scenarios
Given the extremely wide capacity range covered by this core design (30 kVA – 63,000 kVA) and its support for both single-phase and three-phase configurations, its application scenarios effectively span the entire power transmission and distribution network:
1.Distribution Transformers: Commonly utilized in standard 10 kV or 35 kV class small-to-medium distribution transformers (both oil-immersed and dry-type) found in urban areas, residential communities, and industrial facilities.
2.New Energy Booster Stations: Used as the core component for step-up transformers housed within American-style or European-style compact substations required for grid integration in photovoltaic and wind power projects.
3.Large-Scale Transmission and Substation Projects: High-capacity models (63,000 kVA) are suitable for large power transformers deployed in regional substations.
Specialized Industrial Transformers: Applicable to the core assembly of rectifier transformers, electric furnace transformers, and various types of mining-specific isolation transformers.
