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