Abstract
A copper-based winding implementing a copper-based winding of diameter that is typically greater than 90 mm, designed to generate a magnetic field in an electrical contact for a medium-voltage vacuum circuit-breaker. The winding is constituted by a hollow cylinder including helical slots about its longitudinal axis and opening out both into the hollow and to the exterior of the cylinder, winding in which the space between two consecutive slots that form a turn is empty of material and the width of each initial slot is less than 1 mm.
