Support arrangement for a rotatable insulator.

摘要

A durable polymeric bearing (32) is provided for a rotatable support insulator (10). The bearing (32) is of sufficient conductivity to permit the flow of leakage current and capacitive charging current through the bearing (32). Thus, tracking across and/or deterioration of the bearing (32) is avoided since insufficient voltage is developed across the bearing (32) to cause any deleterious effects. <IMAGE>
