HEATER ROD COMPRISING A CASING IN WHICH AT LEAST ONE ELECTRICAL RESISTANCE HEATING ELEMENT IS MOUNTED

摘要

A heater rod has a casing in which at least one electrical resistance heating element is mounted, an internai insulator being placed in the casing to ensure thermal conduction and electrical insulation between the resistance element and the casing, the resistance element being formed from at least one heating wire having a helical geometry and the internai insulator being based on boron nitride.
