Description
Constant Wattage Heating Cable is ideally suited for applications where a particular watt density is required at all times. As their name suggests, constant wattage heating cables are designed to deliver the same power output irrespective of pipe temperature. Constant Wattage Heating Cable has a parallel circuit construction and provides uniform wattage regardless of temperature. We normally supply Heating Calbes with a braid and outer jacket but cables can also be supplied with just a braid. This conctant wattage heating cable is flexible at most ambient temperatures and can be wrapped around piping and complex fittings.
Application
Constant Wattage heating cable can be used for a wide variety of applications including freeze protection of pipework and vessels and process temperature maintenance. Also we supply two types of constant wattage heating cable ; the general for low wattage and the industrial for high wattage.
Constant Wattage heating cable is highly flexible and withstand at Max. 250°c. Although not suited for overlapping, its constant output makes it an ideal choice for higher temperature applications where higher watt densities are required. 		 Constant Wattage Heating Cable
Structure
A. Two tinned copper bus wires are extruded into a silicone/Fluoropolymer core, at a precise distance a notch is automatically cut into the silicone/Fluoropolymer to expose the tinned copper bus wires.
B. A resistance wire heating element is wrapped around the core, this is soldered to the tinned copper bus wires with a high temperature lead free solder and non corrosive flux.
C. A first insulation is extruded over the completed core, a tinned copper braid is added. Over this silicone/ Fluoropolymer outer insulation is extruded.
