Abstract
A lead-trough device for an electrical conductor, which structure includes an insulating body arranged for housing the electrical conductor along a central axis of the insulating body. Further, the lead-trough structure includes insulating layers and conducting layers arranged on the inside of the insulating body, which insulating layers and conducting layers are concentrically wrapped around the central axis of the body and alternatingly arranged along a transaxial direction of the insulating body. At least one conducting layer is wrapped concentrically around the central axis of the body for less than 360° such that ends of the at least one conducting layer are spaced apart.

A lead-trough device for an electrical conductor, which structure comprises:
- an insulating body arranged for housing an electrical conductor along a central axis of the insulating body,
- insulating layers and conducting layers arranged on the inside of said body, which insulating layers and conducting layers are concentrically wrapped around the central axis of the body, said insulating layers and conducting layers being alternatingly arranged along a transaxial direction of said insulating body,
- wherein at least one conducting layer is wrapped concentrically around the central axis of the body for less than 360° such that the two ends of said at least one conducting layer are spaced apart.
