FIELD: electrical engineering.
SUBSTANCE: invention relates to the electrical equipment. Three-phase tape magnetic conductor has ellipse-like cross-section and consists of two identical O-shaped rings and one O-shaped ring enveloping them. Tape for coiling of each of two identical O-shaped rings of magnetic conductor has a geometric shape, described by one parametric relationship, and tape for coiling O-shaped ring magnetic conductor has a geometric shape, described by another parametric relationship. Shaped tape cutting and coiling of one ring are carried out simultaneously in one device.
EFFECT: technical result consists in reduction of weight and dimensions, which provides increased resource reliability.
