ABSTRACT:
Electrical isolation which is required between adjacent windings of a device such as a transformer is provided by wrapping a group of individually insulated conductive cores 62, 64, 66, 68 with multiple turns of a thin tape 32. Use of a thin tape rather than solid insulation provides a long creepage path from the cores 62, 64, 66, 68 to adjacent components. The invention can also be applied to components other than transformers.
