Wuhu Tema Er card security quality valve heat preservation dedicated band

Tema Er brand self-regulating heating cable, mainly 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 good characteristics 特玛尔 cards band possess other heating systems can not match.
