Solar water heater insulation down pipes thaw band

Tema Er brand since the temperature control heating program primarily through Self-Regulating electric heating cables automatic temperature control to complete. Tema Er brand Self-Regulating electric heating cables by the conductive core (PTC layer) and two parallel buses crowded the system, plus an insulating layer, a metal shield, anti-corrosion jacket layer. Wherein the conductive carbon particles made of a resin plus various additives, with a special conductive core processing core with fever. When the conductive carbon particles formed by the compound bond at a certain ambient temperature of the conductive network supplying current through the hotline after power begins with fever; and at higher temperatures, the conductive carbon layer produce micro molecule expands gradually separated from the carbon chain, resulting in smaller network, a sharp rise in resistance, conductor current smaller by reducing the tracer power, then reduce the heat, the entire system is in a steady state is relatively balanced state. When the ambient temperature drops, the plastic conductive body has returned to the micro-molecular contracted state, the carbon particles are joined to form the corresponding circuit tracer heating power and automatically rise. Since the entire temperature control process itself is made of a conductive material to complete the automatic adjustment, the control temperature is not too high nor too low. So the good characteristics of electric heating 特玛尔 possess other heating systems can not match
