Insulating cover having shed-shaped profile and manufacturing method thereof

摘要

Method for manufacturing an insulating body with a predetermined profile for an electrical device. This method comprises the steps of forming a covering body of cross-linkable polymer material on a supporting element, where said body has a first external profile that comprises the envelope of the predetermined profile; to vulcanize the body; and to create the predetermined profile on the external surface of said body by removing portions of said material. The covering body obtained in monolithic vulcanized polymer material comprises a central element and a plurality of frusto-conical sheds formed on it where the internal conical surface of at least one shed forms an angle of less than 80 DEG with the central element and where the external conical surface of at least one shed forms an angle greater than 110 DEG with said central body.
