Rail Transit Transformer Cores

The rail transit transformer cores are used in subway and light rail station power distribution and auxiliary vehicle power systems. These applications demand extremely high reliability. A power failure can directly affect line operation and passenger safety. We understand this special responsibility. When we produce these cores, we focus on safety, consistency, and traceability. All cores are made from genuine grain-oriented silicon steel coils from Baowu or Ansteel. This ensures the magnetic performance and mechanical strength meet the strict requirements of rail transit systems.

Our company has strong experience working with large enterprises. We have successfully cooperated with ABB on past projects. We also maintain long-term relationships with well-known rail transit manufacturers. These include CRRC Zhuzhou Electric and Xiangyang CRRC. These partnerships have made us very familiar with the drawing standards and acceptance criteria for rail transit projects. We have proven production cases for the common capacity range of 30kVA to 10000kVA. We are happy to share references from similar past projects. This helps build your confidence in our rail transit transformer cores.

High-Precision Customization Capabilities

Our production equipment supports high-precision custom processing. All 15 shearing lines use CNC systems. This allows us to control the length and angle of each silicon steel sheet precisely. Our technical team conducts a special process review for each set of drawings. They determine the best lamination scheme and binding process. For non-standard voltage ratings and special installation dimensions, we respond quickly. Our designers can work directly with your engineers to optimize the core solution together. Our rail transit transformer cores are built to your exact specifications.

Dedicated After-Sales Support

We assign dedicated personnel to track domestic rail transit projects. After delivery, we provide technical guidance for installation and commissioning. If issues arise during use, we respond quickly and arrange technical staff to visit the site. For export projects, we provide remote technical support via email or video calls. We also maintain customer files and conduct regular quality follow-ups and visits. We actively collect feedback to improve our products. Your success is our success.
