Based on several experimental results, some hints are presented on the insulation design lor power caoies which are to be used under PWM inverter surge voltages. If there is no fear of water-tree deterioration, the peak voltage can be used as a design basis. However, if the cable is to be used under a wet condition, the number of voltage zero-crossings becomes important, since it highly enhances the water-tree deterioration.
