Enamelled copper magnet wire
Akvaton has drawn and enamelled copper at its own plant in Rivne, Ukraine, since 1991, selling under the Novaton brand. Three round copper grades sit in this category: HeatLine 180 and HeatLine 200 for heat-resistant windings, and SolderLine 180, which solders without stripping.
A note on naming, because it confuses buyers more often than it should. Magnet wire, winding wire, enamelled copper wire, enameled copper wire — all four describe the same product. British and American spellings differ; the wire does not.
The whole chain runs in one building: drawing on SAMP lines with diameter control to 1 µm, enamelling on multi-pass MAG Maschinen ovens with Essex varnishes. The conductor is Cu-ETP or Cu-OF, up to 100% recycled. Everything is built to the IEC 60317 series, tested to IEC 60851, under an ISO 9001:2015 quality system.
What is in the range
- Novaton HeatLine 180 — polyester or polyesterimide enamel to IEC 60317-08. Ø 0.16–2.50 mm, thermal class 180 °C, heat shock 200 °C. Resistant to solvents and transformer oil.
- Novaton HeatLine 200 — dual coat to IEC 60317-13: polyester or polyesterimide base with a polyamide-imide overcoat. Grade 1, 2 and 3, Ø 0.16–2.5 mm, thermal class 200 °C, heat shock 220 °C. Also holds up against refrigerants and freon.
- Novaton SolderLine 180 — self-solderable polyurethane enamel to IEC 60317-51. Grade 1 and Grade 2, Ø 0.28–0.85 mm, thermal class 180 °C, soldering temperature 390 °C.
Every product page carries its dimensional table: nominal diameter, tolerance, insulation thickness, maximum overall diameter. That table is what you size the winding window from. The full list of diameters is in the downloadable datasheet.
Diameters, thermal classes and enamel builds outside the standard list are made to your specification.
What is not here yet: rectangular section. Rectangular copper is offered in the special-insulation and copper busbar categories instead. Drawing to 12×4 mm is already in place, and serial production of rectangular enamelled wire is planned for 2027 on new MAG Maschinen lines.
Winding wire for motors, transformers and generators
The datasheets list traction motors, transformers, non-standard motors, generators and electrical apparatus for HeatLine, and low-power transformers, motors and relays for SolderLine. In practical selection terms:
- Motors. Class 180 suits general-purpose stators; class 200 goes into high hot-spot designs. Both serve series production and motor rewinding equally. Round-section wire for EV traction motors ships today — hairpin windings need a rectangular section, so those wait for the 2027 line.
- Transformers. Anything from low-power units up to distribution transformers. Where the unit runs continuously, class 200 is the usual answer.
- Generators. Rotating machines generally, including wind turbine generators. Inverter transformers for solar installations take the same class-200 grade.
- Coils and small windings. Coils, chokes, solenoids, relays and appliance motors. Where assembly time matters, SolderLine removes the stripping step before soldering.
Ordering direct from the manufacturer
Minimum order on standard items is 3 kg within Ukraine and 20 kg in the EU — low enough that a prototype batch is not a problem. EU customers work through Elktrim Sp. z o.o. in Poland, our representative there, which handles the contract, the invoice in euro and the logistics under EU law.
Standard items ship from EU stock within three weeks. Custom orders run up to 30 days, of which the production cycle itself is 5–10 working days. Wire comes on DIN spools K125–K630, on wooden drums for large batches, or packed to your specification.
Every batch carries a certificate of conformity, a test report referencing the specific IEC 60851 clauses, and an incoming raw-material inspection report.
There is no price list. Pricing follows the LME copper quotation on the day, plus specification, volume and delivery terms. Send us the duty cycle, thermal class and diameter, and our engineers come back within one working day.
