For example: RDP2-J3-30, indicating that the insulating layer is Teflon, the rated output power is 30w/m, the working voltage is 220v, and the single-phase ordinary constant power heating cable

Power Limiting Heating Cable Principle:

Two parallel nickel-copper stranded wires are wrapped in a fluoride insulation layer as a power bus, and a nickel-chromium alloy heating wire is wound outside the inner insulation layer, and the heating wire is welded at regular intervals to form A continuous parallel resistance, when the power copper bus bar is energized, each parallel resistance will heat up, that is, a continuous heating electric heating belt can be cut at will.

Power Limiting Heating Cable specifications and parameters

220v RDP2-J3 parallel constant power limiting heating cable Mainly used in petroleum, chemical, electric power, metallurgy and other pipeline systems, storage tanks, valves, pumps, heat tracing, antifreeze, or process temperature maintenance of instrument pipelines. It is suitable for heat tracing and insulation of long-distance, large-diameter pipelines. It can be used in general occasions and explosion-proof occasions Class I and Class II zone 2,220v RDP2-J3 parallel constant power limiting heating cable.
