Constant Wattage heating cable
*Parallel constant wattage heating cable
	A:Optional Overjacket
	B:standard Metal Braid
	C:Outer Fluoropolymer Jacket
	D:Nichrome Heating element
	E: Fluoropolymer Insulated Bus Wire
	F:Nickel Plated Copper Bus Wire

Parallel Constant Wattage heating cable consists of two parallel nickel coated copper bus wires
encased in a Fluoropolymer insulated jacket with Ni-Cr heating resistance wire wrapped arround the jacket. At specific intervals, The Ni-Cr heating element is soldered to bus wires, Forming a line of parallel resistance modules. When power is applied to the bus wires, Each resistance module heats at a rated wattage output. This creats a consistant wattage heating cable. 

*Series constant wattage heating cable

Series Constant Wattage heating cable consist of one or more resistance heating conducts connected to an electric power supplier. The available voltage is dropped across the electric  resistance Represented by the series heater obeying Ohms law and resulting in a heating effect. The circuit length and the process temperature determine the operating resistance of the conduct. Series Constant Wattage heating cable is used where circuit length exceeds the limitation of the Parallel Constant Wattage heating cable or hight temperature exposure is required.
