ABSTRACT:
A high-voltage insulator which is suitable for use in chambers carrying gas highly charged with solid particles and is used particularly in electrostatic filters used for cleaning an exhaust gas derived from internal combustion engines used to drive motor vehicles. The high-voltage insulator is columnar in structure, having shield-like ribs succeeding one another at intervals, adjacent to each of which in the insulator is one recess. With the remaining insulator parts having a smaller diameter, this recess forms a sharp edge, which defines discharge paths toward the flank of the shield-like ribs. Inside these paths, the insulator is kept free of soot coatings or conductive coatings, so that the insulator itself offers high resistance to leakage currents, which would cause insupportable power losses.
