Abstract
An electrical bushing is disclosed for use in high voltage cryogenic applications. The bushing including first and second bushing portions and an electrical conductor disposed longitudinally within the portions. The electrical conductor has a first terminal extending from the first bushing portion and a second terminal extending from the second bushing portion. The first terminal is configured to couple to a first electrical element at ambient temperature, and the second terminal is configured to couple to a second electrical element at cryogenic temperature. The first and second bushing portions comprise a base insulator material, while the first bushing portion further comprises an environmental protection layer disposed over the base insulator portion.
