Abstract
An insulator for electrically insulating an electrical conductor. The insulator includes a roll defining a central longitudinal through hole along a longitudinal axis of the insulator. The through hole is arranged for allowing an electrical conductor to pass there through. The insulator also includes at least one shed arranged on an outer surface of the roll. The shed includes a shed tip having an outer non-flat curvature defined by a plurality of different radii of curvature and including a most distal point of the shed. An end radius of curvature at the most distal point of the curvature is larger than a first radius of curvature at one side of the most distal point and a second radius of curvature at the other side of the most distal point.

An insulator for electrically insulating an electrical conductor, the insulator comprising:
- a roll defining a central longitudinal through hole along a longitudinal axis of the insulator, arranged for allowing an electrical conductor to pass there through;
