Power Transformer Coil Winding Machines

Custom heavy-duty coil winding equipment for large power transformers.

Broomfield designs and manufactures heavy-duty, high-capacity coil winding machines for large power transformers. Each custom-engineered system is designed to support demanding coil winding applications and a wide range of production requirements.

Systems can be configured for continuously transposed cable (CTC), rectangular copper or aluminum conductor, multiple conductors, insulation handling and custom winding tooling.

Built for Large Power Transformer Coils

Large power transformer winding requires substantial torque, structural strength and precise low-speed control. Broomfield engineers each machine around the customer's coil dimensions, tooling weight, conductor materials, tension requirements and production process.

Applications may include:

• Large power transformer manufacturing.
• Transmission and substation transformers.
• Large oil-filled transformers.
• Specialty reactors and other large electromagnetic coils.

Power Transformer Winding Machine Capabilities

Depending on the application, a Broomfield power transformer winding machine can include:

• Heavy-duty welded steel construction.
• High-load headstock and spindle assemblies.
• High-torque variable-speed drive.
• Precise low-speed winding control.
• Heavy-duty adjustable tailstock.
• Custom faceplates, shafts and mandrels.
• Controlled braking and emergency stopping.
• PLC controls with turns counting and programmable stops.
• Integrated guarding and operator access

Each machine is engineered around the complete rotating load, including the tooling, conductor and finished transformer coil.

CTC and Heavy Conductor Handling

Broomfield power transformer winding equipment can be configured for:

• Continuously transposed cable (CTC).
• Paper-covered rectangular conductor.
• Flat copper or aluminum conductor.
• Multiple parallel conductors.
• Customer-specific insulated conductors.

Guide rollers, pulleys, dereelers and tensioning components are designed around the conductor to provide controlled material delivery and accurate placement while protecting its insulation.
