Abstract

A bushing including a terminal ear and a method of manufacturing the bushing are disclosed. The bushing includes a bushing body which can include side plates, end plates, a bottom plate, and terminal ears coupled to the bushing body. Clamps are attached to the terminal ears to supply electrical current to the bushing to maintain the glass inside in a liquid state. Each terminal ear includes an upper portion and a lower portion. The upper portion is coupled to a side plate of the bushing. A clamp is attached to the lower portion of the terminal ear. The upper and lower portions are oriented at an angle with respect to each other. Support portions are provided along the side edges of the upper portions of the terminal ears. Support portions stiffen the terminal ear, thereby increasing its resistance to bending and fatigue stresses. Support portions do not contact the bushing and therefore do not directly conduct current to the bushing. Accordingly, the temperature of the support portions during operation of the bushing will be lower than the conducting portion of the terminal ears. Since the support portions operate at a lower temperature, the thermal degradation of the terminal ear is reduced.
