Rotor And Stator
Product Description
Transformer cores are a key component in electrical transformers, facilitating efficient energy conversion. Manufactured from high-grade Grain-Oriented (GO) and Non-Grain-Oriented (NGO) Silicon Steel and Electrical Steel, our product range includes EI, Toroidal, C-cores, and other shapes based on customer specifications.
These cores are designed for High Magnetic Permeability and Low Core Loss, which reduces hysteresis and eddy current losses. This design contributes to a transformer’s operational efficiency, controlled temperature rise, and stability.
We provide customization services based on technical drawings and performance requirements to produce core solutions that align with specific application needs.

Application description
Our non-oriented electrical steel is widely used in electric motors, transformers, and precision machinery for its excellent magnetic properties and energy efficiency.

PRODUCT PROCESS
Our streamlined process runs from incoming-inspection, precision feeding, high-grade welding, controlled annealing, uniform coating & drying, to secure packaging-every step engineered for consistent quality and traceability.

VERIFIED QUALITY
Factory Certificates & Product Test
To guarantee benchmark quality, every coil undergoes our "inspect-and-retain" protocol:
● Individual samples are taken from each coil and rigorously tested for corosion resistance, elongation/yield strength, magnetic flux density, core
loss, hardness, insulation resistance, and lamination factor-only coils passing all criteria are released.
● Each retained sample is sealed by coil ID and archived for full traceability.
● A digital dossier is created for every coil; scanning its QR code instantly reveals original test data, production batch, and process parameters--true
"one coil, one code, lifetime traceability."
