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.

Abstract: In one embodiment, the termination apparatus provides a means for terminating certain elongate heat tracing products that have corrugated metal sheaths as outer covering for those elongate heaters. The heat tracing products may include oval corrugated metal sheaths as outer covering. Terminating other types of cables, including cables which provide electrical power or electromagnetic signals, is also contemplated.

Abstract: A cable connector assembly comprising an insulating block defining a plurality of cable receiving channels therein. Each cable receiving channel has an entrance at a periphery of the insulating block. A plurality of ground connectors are coupled to the insulating block and positioned such that a ground connector is located proximate to the entrance of each cable receiving channel. Each ground connector comprises a U-shaped member for engaging a ground braid of a heating cable and a grounding screw for engaging a ground wire of a power cable. A ground linking structure electrically connects the plurality of ground connectors. A plurality of first and second wire connectors are adjustably coupled to the insulating block and positioned such that a first wire connector is selectively extendible into a first side of each cable receiving channel and a second wire connector is positioned to selectively extend into a second side of each cable receiving channel.

Abstract: Particular embodiments generally relate to a heating cable that includes an insulated heating element. The bus wires may be bared in that they do not have an insulation jacket surrounding each of the bus wires. For example, insulation on the bus wires that electrically separates bus wires from heating element 106 is not included. Instead, insulation is included on and surrounds the heating element. A heating element is includes one or more resistance wires and an insulating layer surrounding the one or more resistance wires. For the resistance wires to electrically contact the bus wires, the insulating layer is bared at a plurality of node areas to expose the one or more resistance wires from the insulating layer. The one or more resistance wires are electrically coupled to the bus wires at the plurality of node areas to create a plurality of resistance zones for generating heat.
