Enamelled copper winding wires

01Enamelled copper winding wires

Top quality for you 

Enamelled copper winding wires are an important component in electrical engineering and especially in the manufacture of transformers and electric motors. We stock solderable, heat-resistant and baked enamel wires. All standard wires offered are UL approved. We can offer special wires on request. We are also happy to help you with the current market trend, the edgewise winding of flat enameled wires.

Enamelled aluminum winding wires

02Enamelled aluminum winding wires

Enamelled aluminum winding wire is also used in transformer construction, among other things. In particular, it is used in end devices that require the lowest possible weight and in modules where the poorer properties compared to enamelled copper wires are sufficient.

We sell it as a round enamelled wire according to IEC 60317-25 grade 2 and as a flat enamelled wire according to IEC 60317-73 grade 2.

GRP for Transformer construction

We provide glass fiber reinforced polyester (GRP) profiles primarily for transformer construction as dogbones and corner profiles. In addition to the standard properties, various dimensions are also available in the qualities of self-extinguishing (UL 94VO) and reinforced mat. In addition, round and slot locking bars, square, angle, hat, L and U profiles complement our range. We can offer special profiles on request. You can order all products by the meter or as cut-to-size items, especially according to your requirements.

04Modular bobbin system

The alternative to the coil body

The modular bobbin system is an alternative to the coil body. The main advance is the ability to manufacture self-supporting coils without complex auxiliary structures. In addition to the favorable properties of a conventional bobbin, there is also the advantage of an enlarged, heat-dissipating surface.
