Transformer Core Stacking & Turning Platform | Large Transformer Core Process Equipment
Overview
This transformer core stacking and turning platform represents a heavy-duty specialized tooling system specifically engineered for large and medium-sized transformer core manufacturing processes.
Featuring an innovative modular structure and mechanical turning technology, it effectively addresses three core challenges in transformer core stacking and turning: precision control, safety stability, and process adaptability.
The system eliminates the need for traditional pit foundations, requiring only a ground positioning slot for rapid deployment. While ensuring deformation-free core turning, it significantly reduces equipment investment and space requirements, making it an ideal solution for modern transformer production.
