โœฆ Synopsis

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.

The successful operation of the cable makes us hopeful it can be used for large capacity transmission. Our test line is composed of aluminium stranded hollow conductor, liquid-nitrogen impregnated polyethylene paper electrical insulation, and polyurethane foam thermal insulation.

Polyethylene paper tape wrapped insulation impregnated with liquid nitrogen for cryogenic cables was studied using model cable specimens, 66 k V cryocable samples, and 275 k V cryocable samples. This insulation system performs well in that (1) voltage deterioration is small, (2) thickness dependence
