Coil Winding Section Manager
Detailed Job Description — Transformer Manufacturing Plant, Chittoor

Designation Coil Winding Section Manager
Department Winding Shop – Transformer Manufacturing
Reporting To Head – Manufacturing / Plant Head
Location Chittoor, Andhra Pradesh
Transformer Capacity Range Up to 20 MVA (Power & Distribution Transformers)

Qualification B.Tech (Electrical Engineering)
Experience 15 Years (Transformer / Heavy Electrical Equipment Manufacturing)

JOB PURPOSE
Manage HV, LV, and tapping coil winding operations for power and distribution transformers, ensuring dimensional accuracy, insulation integrity, and turns/tapping precision as per design. Drive winding-shop productivity, quality, and on-time delivery of wound coils to the core-coil assembly section.

PROJECT PHASE RESPONSIBILITIES

- Review winding design (helical, disc, layer, CTC as applicable) and conductor specifications for new orders with the design team.
- Plan and coordinate procurement of conductors (CTC, paper-covered copper/aluminium) and insulation materials (crepe paper, pressboard) with Purchase/SCM.
- Set up winding machines, formers/mandrels, and tooling for current coil geometries and ratings.
- Execute prototype/first coil winding trials and verify dimensions, turns count, and insulation build against drawings.
- Provide winding-shop capacity and lead-time inputs during order scheduling and project planning reviews.

PRODUCTION PHASE RESPONSIBILITIES
- Prepare and monitor daily winding schedules across HV, LV, and tap-winding lines aligned to core-shop output and assembly pull.
- Supervise winding operations for dimensional accuracy, correct turns/tap positions, and insulation layering as per drawing.
- Oversee conductor and insulation material issue, consumption tracking, and scrap control.
- Coordinate in-process checks (resistance, dimension, visual insulation integrity) and manage non-conformances.
- Coordinate drying/pressing of wound coils prior to handover to the assembly section.




- Maintain traceability of conductor batches and insulation material lots used per coil/transformer.
- Ensure timely, quality handover of wound coils to the Core-Coil Assembly section as per schedule.
- Coordinate preventive maintenance of winding machines with the Mechanical/Electrical maintenance teams.

TECHNICAL SKILLS

- Strong knowledge of transformer winding types — helical, disc, layer, continuously transposed conductor (CTC).
- Understanding of insulation systems, electrical clearances, and creepage distance requirements.
- Hands-on experience with manual, semi-automatic, and CNC coil winding machines.
- Ability to interpret winding drawings, calculate turns ratios, and verify tap-changer connections.
- Familiarity with IS/IEC standards governing transformer winding and insulation design.

LEADERSHIP REQUIREMENTS
- Lead winding supervisors, machine operators, and insulation-fitting staff across shifts.
- Coordinate closely with Core Shop, Core-Coil Assembly, Design, and Quality teams.
- Drive training on winding standards, new conductor types, and machine operation.
- Conduct shift handover reviews and resolve production bottlenecks promptly.
- Promote a defect-prevention and continuous improvement mindset on the shop floor.

KEY PERFORMANCE INDICATORS (KPIs)
- Winding defect/rework rate (%).
- Turns and tap-position accuracy (first-pass, %).
- On-time delivery of wound coils to assembly (%).
- Conductor and insulation material yield vs. scrap norm.
- Winding machine utilization/OEE.
- Safety incident rate in the winding shop.

SAFETY & COMPLIANCE RESPONSIBILITIES
- Enforce electrical safety practices while handling conductors and testing equipment.
- Ensure ergonomic lifting/handling protocols for heavy coils and formers (mechanical aids, trained riggers).
- Maintain machine safety interlocks and guarding on winding equipment; enforce LOTO during maintenance.
- Mandate appropriate PPE (gloves, safety footwear, eye protection) in the winding shop.
- Ensure safe storage and handling of insulation materials (paper, pressboard) to prevent fire hazards.
- Comply with ISO 9001 / 14001 / 45001 and plant EHS and housekeeping standards.
