โœฆ Synopsis

Properties of insulation for high voltage cryoelectric equipment are considered. The results of investigations into surface dielectric strength under cryogenic conditions of bushing models made of monolithic teflon are discussed. New designs for heavy current leads for liquid helium cryostats, based on the obtained results, have been suggested and built. The current leads were tested at 80 and 100 kV with 5.5 kA current and the results are presented.

A new design of gas-cooled current leads is described. In order to optimize them, the differential equations of stationary temperature distribution for variable coefficients were solved by means of an analogue computer. The influence of the variable cross-section A(x) and the zero evaporation rate a
