Insulating Materials at Very Low Temperatures: A Short Review

Abstract

In this paper, a short review is given on insulating materials at very low temperatures. Various insulating materials are investigated in terms of phenomena such as partial discharges. Some of the factors affecting the behavior of the insulating materials at very low temperatures, such as the quality of the electrode surface, the stressed insulation volume, and the existing bubbles, are also reported and commented upon. Proposals for future research are also discussed.
