Publication number: 20230411996Abstract: A system for transmitting electrical energy from an energy source to a consumer, e.g., for contactlessly transmitting energy to a mobile consumer, includes a first line conductor and a second line conductor. Each line conductor has, in a respective axial direction, an at least approximately rectangular cross-section, the long sides of which are longer than the broad sides. The axial directions of the line conductors extend at a right angle with respect to a vertical direction. The first and second line conductors intersect in an intersection region in which a holding device is arranged, and are arranged outside the holding device such that the long sides of the line conductor cross-sections are parallel to the vertical direction. The first and second line conductors are arranged in a central region of the holding device such that the long sides of the line conductor cross-sections are oriented at a right angle with respect to the vertical direction.Type: ApplicationFiled: October 6, 2021Publication date: December 21, 2023Applicant: SEW-EURODRIVE GMBH & CO.
