Hefei Ruyue provides high-quality silicon steel cores manufactured from JFE, Nippon Steel, Baosteel and other premium electrical steel materials. Customized toroidal cores, C cores and wound cores for transformers, CT and magnetic applications.
Materials used: We are able to consistently supply world-class, high-quality grain-oriented electrical steel sheets (from Baosteel, Wuhan Iron and Steel, Shougang, Nippon Steel NSC, Kawasaki JFE, POSCO, Amko AK). Available thicknesses include 0.05, 0.08 and 0.10 mm ultra-thin silicon steel sheets; 0.1 mm super-grade silicon steel sheets; and 0.23, 0.27, 0.30 and 0.35 mm standard or high-permeability (Hi-B) silicon steel sheets.
Structural features: Manufactured using in-house developed high-precision automatic winding machines and formed via high-vacuum heat treatment. An air gap is created in the closed magnetic circuit using wire cutting or grinding wheel cutting. Air gap dimensions range from 0.2 mm to 12 mm, with predominantly rectangular or circular shapes. The products feature an aesthetically pleasing appearance, precise dimensions, stable performance and low residual magnetism. Measurement errors are minimal, ensuring high precision.
Applications: Inductors, electrical quantity sensors, current sensors, Hall sensors, Hall linear integrated sensors, magnetic diodes and magnetic transistors.
Specification range: Can be customised to meet a wide range of customer specifications.
We provide high-quality grain-oriented electrical steel (GOES) and non-oriented electrical steel (NOES) materials from leading global steel manufacturers. Various grades are available to meet different requirements for transformers, current transformers (CT), voltage transformers (VT), inductors, and other magnetic components.
