    摘要: The invention relates to a novel design for a winding (8) made of a material having low electrical resistivity, such as copper, and a diameter typically larger than 90 mm, intended for generating a magnetic field in an electric contact (2, 3) for a medium-voltage vacuum bulb (1), consisting of a hollow cylinder (8) including slots (81) free of material and formed helically about the longitudinal axis thereof, and being in communication with both the cavity and the outside of the cylinder. According to the invention, the angular length of each helix is at least equal to 360°. The invention enables an increase in the level of the magnetic field AMF obtained by the winding(s) integrated into an electric contact of a vacuum bulb while enhancing uniformity and field symmetry, and reducing production costs.
