﹛﹛Constant
Wattage cable consists of two parallel
nickel plated copper bus wires encased
in a fluoropolymer insulated jacket
with nichrome heating element wrapped
around the jacket. At specific intervals,
the nichrome 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 rated wattage output. This
creates a consistent heating cable.
Series
Constant Watt Heating Cable。
﹛﹛These heaters consist
of one or more resistance heating conductors
connected to an electrical supply. The
available voltage is dropped across
the electrical 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 conductor. Series Constant watt
heating cable are used where circuit
lengths exceed the limitations of parallel
resistance heating cables or high temperature
exposure is required.
The
Benefits of Constant Wattage Heating
Cable
*The parallel
resistance configuration allows
the cable to be cut to length
*Provide consistent and reliable
heat outputs regardless of circuit
length
*Not subject to the inrush current,
the need for oversizing power distribution
equipment is eliminated.
* Resistance heaters are most often
available for higher operating temperature
applications.
