Precision 45 Mitered Core Laminations: Accurately cut 45-degree miter joints support efficient magnetic flux transfer at core corners, helping optimize transformer core performance.
High-Permeability CRGO Silicon Steel: Manufactured from cold-rolled grain-oriented electrical steel to provide strong magnetic induction and low-loss core material for transformer applications.
Optimized for Transformer Core Assembly: Suitable for assembling three-phase and single-phase transformer cores, including power transformers, distribution transformers, and electrical reactors.
Reduced Magnetic Flux Distortion: The mitered joint design helps guide magnetic flux smoothly through core corners, supporting stable and efficient magnetic circuit performance.
Custom Lamination Dimensions: Length, width, thickness, step-lap configuration, notch position, and miter angle can be customized according to OEM drawings and core-design requirements.
Compatible with Step-Lap Core Designs: Available for step-lap lamination structures, helping reduce localized magnetic loss, vibration, and operating noise compared with basic butt-joint assemblies.
Precision Cutting for Consistent Fit: Controlled cutting accuracy helps ensure reliable lamination alignment, tight core stacking, and efficient downstream transformer-core assembly.
Low Core Loss Material Option: Can be produced using selected low-loss CRGO grades to help transformer manufacturers improve energy efficiency and reduce no-load losses.
Flexible Supply for OEM Production: Available as loose laminations, stacked core parts, or customized core kits to suit different manufacturing processes and assembly lines.
Protected Packaging for Global Delivery: Secure export packaging helps protect precision-cut silicon steel laminations from moisture, edge damage, and deformation during storage and transportation.
