Abstract
An insulator bushing for high d-c voltage input to be used in an electric precipitator, etc. is designed to internally produce jet flows of sealing gas covering the insulator member. While ingress of dust-laden gas passing through the precipitator into the bushing is thereby prevented thus keeping the interior of the bushing clean, the necessary quantity of sealing gas to be supplied can be economically reduced.
