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. 如果运行过程中温度升高, 塑料会膨胀，碳颗粒之间的距离增加, 电阻增加，输出下降. 当环境温度下降时, 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.
特征
• Energy efficient, 当需要较少热量时，自调节电缆使用较少的能量.
•Easy to install, 可以切割成任意长度 (最大电路长度) in the field.•lower installed cost than steam tracing, less maintenance expense and less down time.•Can be single overlapped without burn- 出去, 简化了阀门等在线工艺设备的伴热, elbows andpumps.•Because of self-regulating, over temperature conditions are minimized.•Connection Kits reduce installation time.
