A magnetically shielded cable arrangement, comprising at least two AC cables (201-203) comprising a spaced portion extending between two close portions of parallel cables, such spaced portion sequentially including a diverging portion, a widely spaced portion and a converging portion, and an EMF shielding system (1) laid over said at least two AC cables (201-203), said EMF shielding system (1) comprising a conductor (2, 3, 11, 12) having two branches (2, 3) forming a median portion (4, 5) and end portions (7-10), the median portion width being equal to or larger than the AC cables distance in the widely spaced portion and the width at the extremities of the end portions (7-10) being larger than the AC cables distance in the close portions and smaller than the AC cables distance in the widely spaced portion, said conductor (2, 3, 11, 12) comprising an inner electrical path (2a, 3a) and an outer electrical path (2e, 3e) connected together (11, 12) at relevant longitudinal ends.
A magnetically shielded cable arrangement, comprising:
An electromagnetic field (EMF) shielding for an alternating current (AC) cable system, the EMF shielding comprising:
A method of shielding at least two alternating current (AC) cables at a spaced portion extending between two close portions of parallel cables of the at least two AC cables, the spaced portion sequentially including a diverging portion, a widely spaced portion, and a converging portion, the method comprising:
