The measured dissipation factor and breakdown strength of liquid nitrogen impregnated polyethylene paper insulation for cryogenic power cable are presented. The effect of screening, and impulse and ac deteriorations are discussed. The tests were carried out using model cable type specimens.
A 66 k V fiquid nitrogen cooled cryogenic cable was manufactured and tested using ac and impulse voltages. Liquid nitrogen cooled cryogenic cables will be in practical use over the 275-500 k V range. Study of the 66 kV class cable is the first step towards this development. The insulation system of
