ABSTRACT:
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.
