Abstract

Electrical insulation is provided between two parts of a structure intended for exposure to high temperature radiation from a heat on source, e.g. the interior wall 2 of an electrical discharge furnace, by providing a slot 1 in the structure positioned so that the base of the slot cannot view the heat source 4 directly. The sporadic discharge between the arc electrode 3 and the adjacent part of the insulating wall 2 when its insulating properties are reduced by increasing temperature is prevented, a sporadic discharge occuring instead across the slot 1, The slot may have flared lips, sides generally angled away from each other in the direction of increasing temperature, provisions 9 for a flow of gas in the same direction and provision 8 for cooling the material bridging the base of the slot to a temperature at which it may be electrically insulating. <IMAGE>
