Industry & Occupation
Classification
Summary
Specializes in coil winding operations for generators, handling insulation processing, assembly, inspection, and repair as a technical role.
Description
Coil Winder (Generator) is a specialist role primarily focused on coil winding for generators, including rewinding worn windings, insulation treatment, drying, assembly, and performance testing. Based on design drawings, coils are precisely wound using manual and automatic winding machines, with selection and processing of insulating materials. Post-operation quality inspections are conducted using insulation resistance meters and performance testing equipment, identifying and repairing/adjusting any issues found. Due to handling large coils and working under high voltage, utmost attention and safety management are required.
Future Outlook
While maintenance demand remains stable due to the extended lifespan of power plants, the introduction of automatic winding machines will advance efficiency, potentially reducing some workload.
