Constant wattage electric heating tracing cable RDP3
Application
Constant Wattage Heating Cable is ideally suited for applications where a particular watt density is required at all times. They are flexible and can be cut-to- length in the field. Although not suited for overlapping, its constant output makes it an ideal choice for higher temperature applications where higher watt densities are required. Constant-wattage heating cable provides precise and constant temperatures up to 260°C. Ideal for a wide range of applications, our heating cables ensure power remains constant regardless of temperature! Constant Wattage heating cables are suitable for use in harsh corrosive and hazardous area applications.
Constrution
1.Tinned copper stranded wire
2.FEP insulation layer
3.FEP insulation layer
4.Ni-Cr alloy wire
5.PEP insulation layer
6.Metal braid
7.FEP outer sheath
Working principle
Three 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, repeated cycle connection(like:AB-BC-CA-AB) form the parallel resistance between two phase, finally covered with insulation jacket FEP. When the bus wires power on three phase, each parallel resistance begin to heat.thus form a continuous heating cable.
