Title (EN) VOLTAGE-LEVELING MONOLITHIC SELF-REGULATING HEATER CABLE
(FR) CÂBLE CHAUFFANT AUTORÉGULATEUR MONOLITHIQUE À NIVELLEMENT DE TENSION
Abstract:
(EN) A self-regulating electric heater cable includes a monolithic heater core of PTC material encapsulating a pair of bus wires, and a conductive layer disposed on an outer surface of the heater core such that the conductive layer levels the voltage generated at the outer surface of the heater core when an electric current is passed through the bus wires. The conductive layer draws the current evenly through lobes of PTC material encapsulating the bus wires. The conductive layer may be a coating, such as a conductive ink or paint, or may be an extruded or wrapped material applied to the heater core. Standard heater cable layers are applied oyer the conduetive layer, including an electrically insulating layer that contacts a portion of the conductive layer and also may be separated, at points, §¾rn the conduetive layer by one or more air gaps.
(FR) La présente invention concerne un câble chauffant électrique autorégulateur qui comprend une âme chauffante monolithique de matériau PTC encapsulant une paire de fils de bus, et une couche conductrice disposée sur une surface externe de l’âme chauffante de sorte que la couche conductrice nivelle la tension générée à la surface externe de l’âme chauffante lorsqu'un courant électrique traverse les fils de bus. La couche conductrice attire le courant uniformément à travers les lobes de matériau PTC encapsulant les fils de bus. La couche conductrice peut être un revêtement, tel qu'une encre ou peinture conductrice, ou peut être un matériau extrudé ou enroulé appliqué sur l’âme chauffante. Des couches de câble chauffantes standard sont appliquées sur la couche conductrice, comprenant une couche électriquement isolante qui entre en contact avec une partie de la couche conductrice et peuvent également être séparées, au niveau de points, de la couche conductrice par un ou plusieurs espacements d’air.
