ABSTRACT:
An electrical insulating coating of thermosetting polymeric material for a surge arrester valve element of silicon carbide particles bound together within a ceramic matrix, in which the coating is applied in powder form. Curing of the coating is effected either by a heating cycle following the application of the powder insulating coating, or by preheating of the valve element before application of the powder coating. Alternately, the insulating coating can be applied as a plasma spray, making post-curing unnecessary.
