Title (EN) HEATING CABLE
(FR) CÂBLE CHAUFFANT
Abstract: front page image
(EN)A heating cable includes a bus wire structure that includes a plurality of bus wires. An insulation layer is provided to insulate the plurality of bus wires. A plurality of node areas exposes portions of the bus wires from the insulation. A heating element is wrapped around the bus wire structure in a helical manner. The heating element includes an insulating core and one or more resistance wires wrapped around the core in a helical manner. The heating element is electrically coupled to the nodes of the bus wire structure at the plurality of node areas. The insulating core may be made of a folded-over tape made of a cloth material, such as glass cloth. Pluralities of redundant paths in between two nodes are provided to allow for current to flow in a zone if one of the redundant paths is broken.
(FR)L'invention concerne un câble chauffant qui comprend une structure de fil commun qui comprend une pluralité de fils omnibus. Une couche d'isolation est fournie pour isoler la pluralité de fils omnibus. Une pluralité de zones nodales exposent des parties des fils omnibus à partir de l'isolation. Un élément chauffant est enveloppé autour de la structure de fils omnibus de manière hélicoïdale. L'élément chauffant comprend un noyau isolant et un ou plusieurs fils de résistance enveloppés autour du noyau de manière hélicoïdale. L'élément chauffant est couplé électriquement au nœud de la structure de fil commun au niveau de la pluralité de zones nodales. Le noyau isolant peut être fait d’un ruban replié constitué d'un matériau textile, tel un tissu de verre. Des pluralités de chemins redondants entre deux nœuds sont fournis pour permettre au courant de circuler dans une zone si l'un des chemins redondants est interrompu.
