JNCN Power provides high-performance Transformer Silicon Steel Cores and Laminations engineered for excellence. Designed to serve as the heart of modern power systems, our cores are characterized by ultra-low no-load losses, minimal noise levels, and superior mechanical integrity.
From 10kV distribution transformers to massive 110kV power units, we offer a comprehensive suite of lamination solutions that meet and exceed international efficiency standards, ensuring your transformers operate with peak reliability and a 20-year+ service life.
Advanced "Zero-Stress" Manufacturing Our core processing utilizes internationally advanced, fully automated intelligent production lines. By operating in a dust-free, constant temperature, and constant humidity environment, we eliminate external variables. This end-to-end automation minimizes additional mechanical stress on the silicon steel, significantly reducing the "Process Coefficient" and preserving the material's original magnetic properties.
Superior Magnetic Performance We specialize in producing cores with exceptionally low no-load current and partial discharge. By using premium cold-rolled grain-oriented (CRGO) steel and precision annealing, we achieve excellent magnetic flux distribution, which translates to a quieter, cooler, and more efficient transformer.
Unmatched Dimensional Accuracy With our high-precision CNC slitting and shearing equipment, we guarantee minimal burrs (height <0.02mm) and perfect flatness. This precision allows for a higher stacking factor (space factor), optimizing the transformer’s size and weight while maintaining high mechanical strength and short-circuit resistance.
Intelligent Supply Chain & Fast Delivery Our intelligent workshop doesn't just improve quality—it accelerates throughput. By integrating automated stacking and logistics, we offer some of the fastest lead times in the industry for 110kV-grade core solutions, helping you meet tight project deadlines.
