  • Transformer bushing cap
    Patent number: 4985599
    Abstract: A bushing cap is provided for mounting to a transformer bushing or to a lightening arrestor. The bushing cap when mounted to the bushing acts as an umbrella for the bushing to protect the same from airborne contaminates such as salt spray which can form a conductive surface on the bushing, while providing adequate bottom and side clearance from the bushing to ensure that a conductive surface between the cap and the bushing is avoided.
