Abstract
A continuously transposed cable CTC, extending according to a longitudinal development direction (L) and having two opposite longitudinal ends, includes a plurality of strands arranged so to form at least a first and a second adjacent stacks, each extending along the longitudinal development direction (L), wherein said at least first and second stacks form a longitudinal interface therebetween. The CTC cable (1) further includes one or more optical fibers positioned at the interface between the first and the second stacks. A winding of an electromagnetic induction device, such as a transformer, can be obtained by winding said CTC cable.
