Coils & Windings
Custom coil assemblies, winding assemblies, and core-and-coil builds — preformed and tape-wrapped windings in copper or aluminum, wound and fabricated entirely in-house.
Custom coil assemblies, winding assemblies, and core-and-coil builds — preformed and tape-wrapped windings in copper or aluminum, wound and fabricated entirely in-house.
FabTek is a coil winding company and contract manufacturer of coil assemblies, winding assemblies, and industrial coils — wound and fabricated in-house — built to your specification with the same single-source control we apply to every part.
For transformer OEMs and utility programs, in-house winding means consistent quality and schedules you can plan around. Every assembly is a domestic build under an ISO 9001:2015 quality system at our facilities in Hazlehurst, Mississippi.
Coil assemblies and industrial coils wound and fabricated in-house to your specification.
Preformed and tape-wrapped winding assemblies for transformer and utility applications.
Complete core-and-coil assemblies, primary and secondary windings, fabricated under one roof.
Send a spec or drawings — we build to print.
Transformer coils and windings are the electromagnetic core of every transformer — the components that step voltage up or down across the grid.
FabTek's coiling, winding, and circuit sub-assembly capability lets transformer OEMs and utilities source the electrical build and the surrounding metal from a single domestic partner. These assemblies go into distribution and power transformers, single-phase step voltage regulators, and custom apparatus serving utilities, EPCs, and industrial power users.

Each build moves through our own shop end to end — no outsourced steps, including paint. That's how we hold tolerances and finish quality at volume.
Fabrication runs through our laser cutting, CNC press-brake forming, robotic plasma cutting, welding, and powder-coat finishing — see our full equipment and capabilities for the machines behind each step.
Built at four production sites in Hazlehurst, Mississippi.
ISO 9001:2015 quality management, AWS-certified welding, OSHA-compliant facilities.
In-house powder-coat backed by an IEEE 2000-hour salt-spray certification.
25+ years of fabrication experience and the automation to grow with your volume.
Yes. FabTek winds and fabricates coil and winding assemblies in-house, with single-source quality control.
Yes. We fabricate build-to-print and custom-spec coil and winding assemblies.
FabTek is one of them. We are a domestic coil winding company producing coil assemblies, winding assemblies, and core-and-coil builds under an ISO 9001:2015 system — and we also fabricate the tank and cabinet, so the metal and the electrical come from one supplier.
All assemblies are manufactured in the United States at our facilities in Hazlehurst, Mississippi.
