Marathon Heating cables are constant watt arrangement designed to put out a certain amount of wattage per linear meter of cable. These are generally constructed of two #12-18 AWG polymer insulated parallel bus wires with a nickel alloy heating element wire wrapped alternatively along the insulated bus wires. These connections are made at the’NODE’ point where the nickel-alloy heating element is either welded or connected. The entire element assembly is then dielectrically insulated with an additional polymer jacket. The power output per unit length is constant, regardless of the overall length of the heating unit. The parallel arrangement preserves systems integrity i.e. if any section of cable should fail, the rest of the heater will continue to operate. Ideally suited for applications where a particular watt density is required at all times such as freeze protection and many other low-temperature process control applications
