Abstract

This paper discusses several properties of HV tape-type insulation impregnated with LN₂ for cryogenic cables. Fibrous, film and laminated materials have been tested for their short and long-term properties under AC and impulse voltages. The effect of partial discharges and the relationship between the AC and the transient characteristics of the insulation are discussed
