ABSTRACT:
A shutter for high voltage metal clad switchgear is taught which is a composite of electrically insulating material such as polyester and islands of electrically conductive material such as non-magnetic aluminum. The polyester material reduces the chance for flash-over between the high voltage conductors and the grounded metal islands or other conductors, while the grounded metal islands provide a region of zero ground potential in an area associated with the opening in high voltage terminal assemblies to thus assure that personnel who approach this region will always be exposed to ground potential and not high voltage potential.
