✦ Synopsis

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 is small, and (3) dissipation factor is small. This insulation system is one of the most promising systems for a large capacity transmission cryogenic cable.
