ABSTRACT:
An improved electrical bushing uses a refrigerant to provide cooling of both the bushing and the electrical apparatus to which the bushing is connected. The refrigerant vaporizes inside the hollow conductor of the bushing at the hot contact end, and flows to a heat dissipating device connected to the terminal end of the conductor. A liquid collecting plate collects the refrigerant which has liquefied in the heat dissipating device, and a slender tube inside the conductor transports the liquid refrigerant back to the contact end without the refrigerant contacting the intermediate portion of the conductor.
