Саморегулирующийся нагревательный кабель для защиты от замерзания промышленных

Introduction

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 provides an economical alternative to self-regulating heating cable but requires more skill for installation and more advanced control and monitor systems. 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.

RDP₂ Single phase constant wattage heating cable used to freeze protection, heat preservation for all kinds of pipelines and instruments. 

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

RDP₃ Three phase constant wattage heating cable

Three phase constant wattage heating cable adopt three phase triangle power supply, have the characteristics of single phase constant power heating cable, special used for long distance and large diameter pipeline's heat tracing and preservation. 

Applications

such as factory Zone 1, Zone 2 explosive gas mixture T3 area.

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 phases, each parallel resistance begin to heat, thus form a continuous heating cable.
