Coil Winder

Division: Substation
Location: Ellisville, MS
Equal Opportunity Employer Vet/Disabled

Job Description

We are seeking a highly skilled Senior Coil Winder specializing in large-scale power transformers.
In this role, you will be responsible for the using specialized winding techniques, including Disc, Helical, and CTC
(Continuously Transposed Conductor) winding. This position requires a mastery of tension control and the ability
to interpret complex engineering blueprints to ensure optimal electrical performance and mechanical strength.

Responsibilities

• High-Voltage Coil Winding: Set up and operate heavy-duty winding machines to produce coils for transformers rated at 161 kV, 230 kV, and 345 kV.
• Winding Techniques: Execute complex winding patterns including:
o Disc Winding: Stacking multiple conductor discs in series with precise crossover points.
o Helical (Spiral) Winding: Managing high-current, low-voltage applications using multiple parallel conductors in a spiral configuration.
o CTC Winding: Handling Continuously Transposed Conductors to minimize eddy current losses and ensure uniform current distribution.
• Blueprint Interpretation: Read and interpret detailed engineering drawings, BOMs (Bill of Materials), and winding specifications to determine turns, dimensions, and insulation requirements.
• Insulation & Assembly: Apply critical insulation materials (kraft paper, epoxy resin, press-board spacers) and create axial/radial oil ducts to facilitate efficient cooling.
• Quality Control: Monitor turn counts, DC resistance, and layer appearance during the winding process; conduct final inspections to meet strict industry standards.
• Maintenance & Safety: Perform routine machine maintenance and adhere to safety protocols, including Lockout/Tagout (LOTO) and the use of specialized PPE for high-voltage environments.

Skills/Qualifications

• Experience: 5+ years of experience in high-voltage power transformer coil winding
• Technical Proficiency: Expert knowledge of vertical, disc, helical, and CTC winding methods for core-type transformers.
• Precision Tools: Ability to use micrometers, calipers, and measuring tapes to verify tolerances within fractions of an inch.
• Physical Stamina: Capability to stand for long periods and lift materials up to 25–100 kg as required by the manufacturing environment.
• Education: High School diploma or equivalent; vocational training in electrical technology is preferred.
Preferred Skills
• Experience with CNC-controlled automated winding machines.
• Knowledge of interleaved or shielded disc construction for enhanced surge behavior.
• Familiarity with soldering and welding lead-out conductors and busbars
