Insulating strip has edges notched and hoardings, in particular for the transformer, and a transformer comprising such an insulating strip

摘要

It is an insulating strip (14) which at least one of the edges (15) is notched, this edge (15) being at least locally provided with slots (16), which, extending generally transversely from its edge (17), delimit between them of the notches (18). br / according to the invention, it is attached, the length of this notched edge (15), on at least one of the faces that - ci, an insulating tape (20), which covers continuously its notches (18), and which is capable of elongation. & br / application, in particular, to the electrical insulation between two windings in a transformer.
