Enamelled Wire
Enamelled Winding Wire
Enamelled wire, also known as magnet wire or winding wire, made by coating a thin layer of insulation such as enamel or polyurethane over a conductive core of copper or aluminium. The insulation prevents short circuits between adjacent turns.

Product Overview
Enamelled wire, also known as magnet wire or winding wire, made by coating a thin layer of insulation such as enamel or polyurethane over a conductive core of copper or aluminium. The insulation prevents short circuits between adjacent turns. Production covers conductor thickness from 0.8 to 5.6 mm and conductor width from 2.00 to 16.00 mm, at a width to thickness ratio of 1.4:1, and the wire can be supplied solid or stranded. The product category includes 130 class polyester enamelled wires.
Key Benefits
- Insulation coating gives high electrical resistance and thermal stability
- Copper or aluminium conductor depending on conductivity and cost requirements
- Solid or stranded construction for the flexibility the winding needs
- Rectangular conductor sizes from 0.8 x 2.00 mm up to 5.6 x 16.00 mm
- Specifications beyond the standard range quoted on request
Problems It Solves
- Short circuits between turns where insulation is inadequate
- Insulation breaking down at the winding's operating temperature
- Conductor sizes not available from local stockists
- Flexibility requirements that a solid conductor cannot meet

Compared With The Alternatives
| Foil windings | Foil gives a high fill factor for large section windings; enamelled wire is the practical choice for smaller coils and for windings with many turns. |
|---|---|
| Copper versus aluminium conductor | Copper conducts better in the same cross section; aluminium is lighter and cheaper, so the winding has to be larger for the same performance. |
Use Guide
- Match the insulation thermal class to the winding's operating temperature
- Confirm the conductor dimensions against your winding machine's capability
- Choose stranded construction where the winding has tight bends
- Ask about specifications outside the standard range rather than compromising the design
