Abstract: The present invention is an oil-free apparatus bushing with a silicone-rubber housing bonded directly to a capacitance-graded core, and a method for making an apparatus bushing with a silicone-rubber housing bonded directly to a capacitance-graded core. The silicone-rubber housing has numerous performance, environmental, and safety advantages over the traditional oil-filled porcelain bushings that are well known in the art. The advantages include eliminating moisture ingress, eliminating the need for oil, which can cause environmental contamination, and eliminating porcelain which in the event of a violent failure can cause flying damaging debris.
