When it comes to winding aluminium strip, we roll out our extensive know-how for you
We supply our customers with high-grade coils for use as a conductive material made exclusively from ANOFOL. The ANOFOL strip used for the coils have a clean edge profile, since the edges are thoroughly machined and thus the strip does not have sharp edges or burrs. A vital prerequisite for producing a flawless anodised coating and also for minimising the risk of voltage flashovers or short circuits caused by the development of excessive field strengths.
Precision is our strength
Precise, lightweight, and temperature-resistant – those are the properties that distinguish ANOFOL coils. Steinert’s high-precision winding method allows us to produce coils with extremely thin and flat ANOFOL strip. Winding tolerances of <100µm can be realized, regardless of the number of coils that need to be produced. Another benefit: ANOFOL eliminates the cavities and loss of space that occur with copper wire winding, resulting in a greater filling factor. In addition, the extremely thin insulation layer ensures optimal dielectric strength and thermal conductivity. And speaking of heat: ANOFOL coils can be used in continuous operating temperatures up to 500° C. In contrast, copper requires pre-treated wires for temperatures above 180° C. We use state-of-the-art non-contact measuring instruments to scrupulously verify the accuracy of precision coils.
