Core Type Transformer Core

The core type transformer core is the most mainstream and common structure in the transformer industry. Its key feature is that the windings (coils) directly surround the core limbs. This structure focuses the magnetic path within the limbs. It results in low leakage flux and high material utilization. The common forms include three-phase three-limb and three-phase five-limb types. We can custom produce both types based on your drawings and technical requirements. The capacity covers 25kVA to 10000kVA. The voltage rating supports 10kV to 110kV. Our core type transformer core is the reliable choice for most applications.

Our company has been working in this field for 26 years. We have 100 employees. This team includes 2 professional designers and 6 quality inspectors. Our team has deep practical experience in core-type core lamination, joint design, and dimensional control. All materials we use are genuine silicon steel coils from major mills like Baowu and Ansteel. Common thickness options include 0.23mm, 0.27mm, 0.30mm, and 0.35mm. We recommend the best thickness and grade combination based on your required efficiency level. Our core type transformer core is backed by decades of expertise.

Special Attention to Joint Connections

The main challenge in core-type core manufacturing is the connection between the limbs and the yokes. Excessive magnetic resistance at the joints directly increases the no-load loss of the transformer. We use a multi-step staggered lamination method. This distributes the joint gaps evenly across different positions. It prevents magnetic flux from being blocked on any single plane. Our workers follow the layout plan layer by layer. Our inspectors use special gauges to check the offset distance at each joint. This ensures the lamination plan is executed correctly. Our core type transformer core minimizes joint losses.

Complete Quality Control from Material to Finished Product

We understand the decisive role of the core-type core in overall transformer performance. This is why we have a complete quality control system from raw material entry to finished product shipping. Each core undergoes a 100% full inspection before shipment. The inspection includes lamination thickness, limb verticality, joint gaps, and appearance quality. We also accept third-party inspections or factory visits. We believe that transparent manufacturing and strict quality control give our clients confidence. Our core type transformer core is quality you can count on.
