Constant Wattage Heating Cable

Nickel-chromium alloy wire contacts bus wires at regular intervals
Parallel connection to each heating zone
Nichrome wire diameter determines the output power per unit length
Output power constant, independent of temperature changes

Advantages of parallel constant wattage cables
Parallel bus wires so it is fault tolerant
Can be cut to length on site
Can not overlap or spiral wrap
Highest maintain temperature 174 degC
Maximum exposure temperature 200 degC
Starting current = operating current, so no need to consider the instantaneous starting current
Output power and high precision
Corrosion-resistant jacket
Operating voltage 120 volts, 208-277 volts and 480 volts
