220v flexible spiral cable antifreeze Self Regulating Heating Cable Youyu for outdoor Oil Well

Product Introduction

Electric self-regulating temperature heating cable is the only one of electric thermostatic product of new generation, constructed of a semiconductor heater and two parallel bus wires with the addition of insulation layer. The heating elements are parallel to each other and its resistivity has a high Positive Temperature Coefficient” PTC”.

In each heating tracing band, circuits between the bus wires change with the ambient temperature. As temperature decreases, the heater’s resistance decreases which produces more output wattage; conversely, as temperature increases, resistance increases which lower the output wattage, loop back and forth.

The advantage of electric self-regulating temperature heating cable with other heating tracing products is that the temperature can be regulated automatically in a proper range.
