Industry & Occupation
Classification
Summary
A manufacturing job that stacks thin steel plates forming the core of a transformer, manages dimensions and quality, and fixes and insulates them.
Description
Core stacker (transformer) is responsible for the manufacturing process of stacking thin steel plates that constitute the magnetic core part of a transformer, ensuring appropriate dimensions and alignment accuracy, and fixing and insulating them. Align the steel plates while stacking, insert insulating paper or tape to prevent magnetic flux leakage. Measure dimensions with calipers or micrometers and perform quality inspections. Comply with safety rules, and engage in standing work in high-temperature, heavy labor environments, and teamwork.
Future Outlook
While stable increases in demand for transformers for power infrastructure, renewable energy, and EVs are expected, there is a growing trend towards requiring skills in machine operation and programming due to advances in automation and robotization.
