About Us
Transformer Core & CRGO Processing Manufacturer
Chenfan Electric is a manufacturer of laminated transformer cores, Multi-Step Lap (MSL) cores, and custom-width CRGO / GOES slitted coils based in Baoding, China. With 15 years of experience in CRGO and transformer core manufacturing, we supply transformer core products to transformer manufacturers, including TBEA.
Our transformer cores are produced according to customer drawings, including core dimensions, step-lap structure, material thickness, grade requirement, no-load loss target, and packing method. Key process controls include burr height below 0.02 mm, controlled step-lap alignment, and stacking factor target above 97% under suitable material and core structure.
We support transformer manufacturers with CRGO slitting, core cutting, core stacking, inspection, and export packing. Our focus is stable core quality, clear technical communication, and reliable delivery for long-term transformer manufacturing projects.
Vision / Mission / Values
To become a reliable transformer core and CRGO processing partner for transformer manufacturers worldwide.
To provide accurately cut, well-stacked, and export-ready transformer cores based on customer drawings and technical requirements.
Precision, consistency, honest communication, and long-term manufacturing reliability.
Premium CRGO Sources
We source top-tier grain-oriented electrical steel directly from world-class mills. This guarantees consistent magnetic properties and ultra-low no-load loss for your transformer cores.
Our R&D Strength & Certifications
Why Leading Transformer Manufacturers Choose Chenfan?
Precision Processing: Our CRGO cores are processed using state-of-the-art CNC longitudinal and transverse shearing lines. We strictly control the burr level to below 0.02mm, significantly reducing eddy current losses.
Superior Material Sourcing: We utilize high-grade silicon steel from top-tier mills (like Baosteel/Shougang), ensuring an ultra-high stacking factor (up to 97%+) for maximum magnetic efficiency.
Proven Supply Chain Excellence: As a certified supplier for industry leaders like TBEA, and with successful high-capacity projects in Vietnam and Southeast Asia, we understand the rigorous standards of national grids.
Customization & SKD Support: Beyond standard cores, we provide SKD/CKD solutions and technical on-site guidance to help local manufacturers optimize their assembly process and reduce import duties.
