Abstract :
The thermomechanical properties of a practical, crosslinked EHV cable insulation material have been investigated via lathed film samples. Multiple relaxation processes are observed and discussed with regards to their effect on the short-term electrical breakdown behaviour of this material. The effect of mechanical deformation on breakdown behaviour is also investigated. It would appear that lathing induces significant damage.
