โฆ Synopsis
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.

This paper surveys the experimental and theoretical investigations on current induced losses of high power cables. Measurements on compact and tube conductor cable models have been carried out at room temperature and liquid nitrogen temperature (77 K). Further measurements on a 2000 mm 2 fully trans
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
