How Constant-Wattage Cable Works
Constant-Wattage cable uses a fixed resistance wire wrapped around two main conductors ( bus wires ). At specific intervals the insulation is removed from the bus wires , forming the Contact Module Points .
These Contact Module Points are staggered along the length of the cable . This creates consistent heating circuits known as the Module Length . When power is applied to the bus wires each complete Module Length heats at the rated wattage output .
The incomplete Module Lengths , at the beginning and end of each cable , do not heat . This allows the “ Cold ” ends to be safely placed inside of a controller or junction box .
