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 Benefits Medical Insurance Dental Insurance Disability Insurance Life Insurance 401K Retirement Education Reimbursement Paid Holidays Paid Vacations Salary Career Level Required Experienced (Non-Manager) Experience Required 5+ to 8 years Education Required High School Diploma Job Type Employee Job Status Full-Time
