Abstract
A current interrupter assembly includes an insulating structure, a current interrupter embedded in the structure, a conductor element embedded in the structure, a current interchange embedded in the structure and connected to create a current path between the current interrupter and the conductor element, and a semiconductive layer covering at least a portion of the conductor element so as to reduce voltage discharge between the conductor element and the structure.
