Anti-condensation type supporting ceramic sleeve

The utility model discloses an anti-condensation type supporting ceramic sleeve which comprises an insulating ceramic sleeve, a heating body, a wiring seat and a binding post, wherein the heating body and the wiring seat are arranged in a trench in the lower part of the insulating ceramic sleeve; the two ends of the heating body are respectively connected with the wiring seat; the binding post is fixed on the wiring seat. The anti-condensation type supporting ceramic sleeve is simple in structure, high in heat stability, low in energy consumption, long in service life and high in reliability; by the unique anti-condensation effect and the compact insulating structure, the reliability of high-voltage insulation in an electric dust collector can be obviously improved; the insulating ceramic sleeve is 95 corundum ceramic formed by isostatic compaction, so that the anti-condensation type supporting ceramic sleeve is higher in heat shock resistance and high in heat conduction performance, so that internal heat type heating anti-condensation manner is available.
