| Product Name: RDP2 Product 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. Application 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. Working principle Two paralleled stranded copper s ulation layer FEP,then wrap the nickel-chromium alloy as the heating ith bus ar intervals,form the parallel resistance.finally covered with insulation jacket FEP.When the bus ,each parallel resistance begin to form a continuous heating cable. Structure 1.Tinned copper stranded rc;  2.FEP insulation layer  3.FEP insulation layer   4.Ni-Cr alloy insulation layer 6.Tinned copper Metal braid 7.FEP outer sheath RDP2 Single se constant wattage heating cable used to freeze protection,heat preservation for all kinds of pipe instruments.Application such as factory Zone 1,Zone 2 explosive gas atmosre area. Rated voltage:220V          Max exposure temperature:205°c Normality insulation resistance:≥20M ohm       Protection level:IP54 Dielectric strength:2000V 50Hz/1min Insulation material:FEP          Size:6.3×9.5mm Approvals: CE GOST Product Name: RDP3 Product 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.
