ABSTRACT:
An electrical apparatus having a casing with an electrical conductor disposed therein and a vapor lift pump for applying a vaporizable liquid coolant to the electrical conductor to effect cooling of electrical conductor by vaporization of the applied liquid coolant. A non-condensable gas acts as a padding gas at low temperatures and is circulated through the vapor lift pump from a gaseous inlet. The vaporizable liquid is driven by the non-condensable gas onto the electrical conductor, vaporizes, recondenses on the casing wall and returns to a reservoir where it is again picked up by the non-condensable gas.
