Parallel constant wattage heating cable RDP2

Parallel constant wattage heating cable can be used for pipe and equipment freeze protection and process temperature maintenance requiring high power output or high temperature exposure. This type provide an economical alternative to self regulating heating cable but requires more skill for installation and more advanced control and monitor system.Constant wattage heating cables can provide process temperature maintenance up to 150°C and can withstand exposure temperatures up to 205°C with power on.

1.Tinned copper stranded wire

2.FEP insulation layer

3.FEP insulation layer

4.Ni-Cr alloy wire

5.PEP insulation layer

6.Tinned copper Metal braid

7.FEP outer sheath

Two paralleled stranded copper wire as the bus wires with insulation layer FEP,then wrap the nickel-chromium alloy as the heating wire connect with bus wires at regular intervals,form the parallel resistance.finally covered with insulation jacket FEP.When the bus wires power on,each parallel resistance begin to heat.thus form a continuous heating cable.
