Product Overview

12~380V Pipe Electric Heating Cable Self Regulating Heating Cable

Self regulating cables have an adaptable heat output and consist of two parallel bus wires embedded in a networked plastic heat element with surrounding carbon particles. If the temperature increases during operation, the plastic will expand and the distance between the carbon particles increases, resistance increases and output drops. When ambient temperature falls, this process is reversed and heat output increases – this is the principle of self regulation.

Self regulating cables intelligently adjust heat output according to ambient or air temperature – whenever the heat loss of the insulated pipe, tank or heated process increases (as ambient temperature drops), the heat output of the cable increases. Conversely, when the heat loss decreases (as the ambient temperature rises or product flows), the heating cable reacts by reducingits heat output.

Feature

• Energy efficient, self-regulating cable uses less energy when less heat is required.

•Easy to install, can be cut to any length (up to max circuit length) in the field.•lower installed cost than steam tracing, less maintenance expense and less down time.•Can be single overlapped without burn- out, which simplifies heat tracing of in-line process equipment such as valves, elbows andpumps.•Because of self-regulating, over temperature conditions are minimized.•Connection Kits reduce installation time.
