From bare aluminium to enamelled wire

Follow the wire through our enamelling line: off the bobbin, pre-heated, coated with enamel and baked in the curing oven over several coating passes, then wound onto the finished spool.

01Bobbin Loading & InputRaw wire on bobbins loaded into rack.
02Annealing / Pre-heatFirst heat stage to prepare wire surface.
03Enamelling Machine EntryWire is fed into the coating process.
04Integrated Curing OvenHigh-temperature bake to finalize coating property.
05Multiple Coating CyclesMultiple enamel layers applied with drying cycles.
06Finished Wire Take-upAutomated take-up for completed wire spools.

Inside the conductor

Both our wires are solid, round conductors with a continuous enamel coat, in aluminium and in copper. Drag either model to see where the coat ends and the bare metal begins.

Frequently asked questions

What is enamelled winding wire?

A conductor — aluminium or copper — coated with a thin layer of insulating enamel. The enamel lets turns of wire sit tightly against each other in a coil without short-circuiting, which is why it is also called magnet wire. TURBOLINE supplies both: enamelled aluminium winding wire and copper winding wire.

Should I choose aluminium or copper wire?

Copper conducts better, so a copper winding is more compact for the same resistance. Aluminium weighs about 30% as much as copper and is generally lower in cost; it conducts roughly 61% as well, so an aluminium winding uses a larger cross-section for the same resistance — and still weighs around half as much. The right choice depends on your design’s space, weight and cost targets. We supply both and can help you compare.

What types of copper winding wire do you supply?

Enamelled copper winding wire and poly-wrapped copper winding wire, across SWG gauges and thermal ratings, including Class H and Class C. Enamelled wire is insulated with a thin coat of enamel; poly-wrapped wire is insulated with a wrapping of polyester film. Tell us your application and we will advise which suits it.

What sizes are available?

Enamelled aluminium winding wire from 4.00 mm to 0.120 mm (8 – 42 SWG), in Grade 1 (fine), Grade 2 (medium) and Grade 3 (thick) covering. Copper winding wire from 1.219 mm to 0.071 mm (18 – 45 SWG), with technical data for every size in the copper table on this page. Custom sizes are available on request.

Which enamel types and thermal ratings do you offer?

Our aluminium winding wire is polyester and super-enamelled, and the enamel can be supplied from polyester to DC to suit your requirement. Copper winding wire is available in various thermal ratings, including Class H and Class C.

Which standards and certifications apply?

Both products are made as per IS / IEC / NEMA standards. Turbo Wire Industries is certified to ISO 9001:2015 and holds a RoHS certificate of compliance, both issued by PROCert UK and both covering enamelled aluminium and enamelled copper wire. The certificates are shown on our Certifications page.

Which spool types and packing do you use?

Spool types PT-4, PT-15, PT-18 and PT-25, packed in a polythene wrapper. Tell us if your process needs a particular spool.

What is the lead time?

Lead time is 5 – 7 days.

Can we get samples or run a trial first?

Yes. We provide samples, support customer trials and supply test reports, along with any other technical support you need.

What information do you need for a quotation?

Whether you need aluminium or copper wire (and for copper, enamelled or poly-wrapped), the conductor size, enamel type or thermal class, spool type, the standard you work to, quantity, packing and delivery location. If you are unsure of any of these, describe your application and our team will help you work it out.
