Abstract

L'invention porte sur un élément chauffant à conducteur isolé, lequel élément peut comprendre un conducteur électrique qui produit de la chaleur lorsqu'un courant électrique est délivré au conducteur électrique. Un isolateur électrique entoure au moins partiellement le conducteur électrique. L'isolateur électrique comprend une résistivité qui reste sensiblement constante, ou qui augmente, au cours du temps, lorsque le conducteur électrique produit de la chaleur. Un conducteur électrique externe entoure au moins partiellement l'isolateur électrique.
