Abstract

The wafer (10-1-10-4) has outlets of 6 to 7 kilovolts spaced at 120 degrees with an inlet at 0 Volts of a rolling bearing. The inlets and outlets are accessible from exterior of a resin ring. One of the outlets corresponding to different voltage of the other outlet is accessible from exterior of the ring. The ring has lateral protrusions (12-0-12-2), where each inlet and outlet are connected to different protrusions and opens on both sides of the protrusion.
