The silicon steel core for dry type transformers forms the main magnetic path of the transformer. It directly affects no-load loss and load loss performance. At Wuxi Zhongpu Electric, we understand that material selection is critical because it directly influences core performance.
This is why we only use genuine cold-rolled grain-oriented silicon steel coils from leading steel manufacturers such as Baowu and Ansteel. We provide multiple thickness options, including 0.23mm, 0.27mm, and 0.30mm. These options allow us to meet different efficiency requirements for various transformer applications.
Our factory has 26 years of experience in this industry. We currently have 100 employees, including 2 professional designers and 6 quality inspectors.
For our silicon steel core for dry type transformers, we use automated CNC equipment on our shearing lines to ensure accurate cutting. This process minimizes dimensional errors caused by material thickness variations. Every silicon steel sheet is processed with consistent dimensions.
This high precision helps reduce noise and vibration in the finished core. These advantages are especially important for transformers installed in buildings or indoor environments with strict noise requirements.

Comprehensive Product Range and Strict Inspection
We offer a wide range of products. Our cores are compatible with SCB12 to SCB18 series transformers. The capacity range covers 25kVA to 10000kVA, with voltage ratings up to 110kV.
All products are customized according to customer drawings. We manufacture not only standard laminated cores but also customized silicon steel sheet structures with complex shapes.
To ensure reliable quality, we implement a 100% inspection process. Every core undergoes electrical performance testing and appearance inspection before packaging. We also support third-party factory inspections according to customer requirements.
Our silicon steel core for dry type transformers is manufactured with strict quality control and reliable performance.
Service as Important as Product Quality
We always place customer service and product quality at the same level of importance. Before sales, we provide support with material selection and structure analysis.
After delivery, we continue to provide technical assistance. For international customers, we respond quickly to technical questions through email and online communication.
We understand that every core represents your expectations for quality and reliability. Therefore, we maintain transparency and responsibility throughout the entire process. From steel purchasing to final shipment, we work to become a dependable partner for our customers.
