摘要： A cartridge heater for high-voltage applications is disclosed. In one embodiment, the cartridge heater is substantially elongate and cylindrical, and comprises an outer stainless steel sheath having an outside diameter on the order of one-half inch or less. Within the outer sheath is a resistive heating element coiled around an inner, electrically insulating wind core. A substantially hollow cylindrical core sleeve is disposed around the heating element and wind core, electrically insulating the heating element from the outer sheath. In one embodiment, the core sleeve is composed of pre-compressed magnesium oxide.
