A cartridge having at least three shields including a mid-potential shield between two contacts and at least one partial shield between a mid-potential shield and one of the contacts, the distance between the mid-potential shield and the contacts being such that the electric field present at the edge of the contact extends from the contact to the partial shield surrounding it, or vice-versa from the partial shield to the contact, depending on the polarity of the voltage.

An improved high voltage insulator includes a central core and an insulating body fitted tightly around the central core. A flexible coating layer is interposed between a part of the central core and the insulating body. The flexible coating layer fills in shrinkage cavities and compensates for a retraction effect caused by injected material used in forming the insulating body. The insulating body is overmolded to the central core previously coated with the flexible coating layer with an injected insulating resin such as a thermoplastic or thermosetting resin. The insulator could be used as a capactive divider or bushing insulator.

High voltage insulator

A process of manufacturing an insulator having a central core and an insulating body fitted tightly around the central core includes interposing a flexible coating layer between a part of the central core and the insulating body. The flexible coating layer fills in shrinkage cavities and compensates for a retraction effect caused by injected material used in forming the insulating body. The insulating body is achieved by overmolding the central core previously coated with the flexible coating layer with an injected insulating resin such as a thermoplastic or thermosetting resin. The insulator could be used as a capacitive divider or bushing insulator.
