| Zusammenfassung: | A heating element unit for an electric resistance heater comprises: a casing; a heating element within the casing; an electrical supply pin in electrical contact with the heating element; an electrically insulating filler between the heating element and the casing; and an electrically insulating barrier provided between portions of the heating element, the electrical supply pin and/or the casing. The electrically insulating barrier has a greater dielectric strength than the electrically insulating filler, and the dielectric strength of the electrically insulating barrier is greater than about 1500 kV/m (greater than about 40 V/mil). |
