 | For applications at frequencies higher than that of the normal power frequency (50 or 60 Hz), it may be necessary to select a thinner steel to maintain low losses. A range of products for application at medium to high frequencies (200 -3000 Hz) has been developed. | | The thin non-oriented steels are available with an insulating coating, Suralac®7000 (see separate page), or as uncoated strip. Tolerances and dimensions may differ between the grades, so please refer to the separate catalogues, which can be downloaded. | |
