Oil-immersed Transformer Core-type Core

The oil-immersed transformer core-type core is the most common design in oil-filled transformers. In this structure, the coils surround the core limbs. This gives a concentrated magnetic path with low leakage flux. We put structural precision first when we make these cores. The cross-section shape of the limbs, the joint gaps, and the vertical alignment directly affect the temperature rise and noise level inside the oil. We use high-permeability grain-oriented silicon steel from Baowu and Ansteel. This ensures a smooth magnetic flux path. You get a core that performs well in demanding conditions.

Our factory has 100 employees. This includes 2 designers and 6 full-time quality inspectors. Our team has extensive experience in oil-immersed core-type cores. We know the standard requirements for state grid and rural grid transformers. We are also skilled at handling non-standard requests from clients. For example, some clients ask for special limb diameters or yoke dimensions. We can achieve this by adjusting our shearing and lamination processes. Our 19 utility model patents support this flexibility. These patents cover lamination platforms, positioning tools, and testing equipment. Our oil-immersed transformer core-type core is a product of this deep expertise.

Efficient Production and Fast Delivery

We have 4 slitting lines and 15 shearing lines in our facility. From uncoiling to final lamination, our production line operates efficiently. The standard lead time for regular orders is 15 to 20 days. For repeat orders, we can shorten this period because the process parameters are already set. We always confirm the delivery schedule with you before production starts. This ensures our production capacity matches your timeline. We cover S11 to S22 sequences. The capacity starts at 25kVA and goes up to 10000kVA. The voltage rating is 10kV to 110kV. Our oil-immersed transformer core-type core is delivered on time.

Transparent Quality and Third-Party Acceptance

Every core undergoes electrical performance testing before it leaves our factory. We accept third-party inspections arranged by you. We also welcome you to visit our factory to supervise production. Each core shipment comes with a test report. This gives you clear data for your records. We believe that transparency and honesty are the foundations of long-term cooperation. Our goal is to be a partner you can count on for every project.
