Mechanical and ageing tests on partially conducting insulators for use at 25 kV 50 Hz (TM-ETR-66)

Work on a semiconducting insulator for use at 25 kV has continued since the last report which showed that a silicon carbide filled resin system provided a promising formulation for a discharge resistant insulator. Developments to this insulator have been made to flexibilize the system, optimise cure schedules, and improve...
