加热保温罩是将电能转化成热能再配和特殊工艺复合而成的可拆卸柔体节能保温加热形式。其可以以任何形状使用在您所需要的设备部件上。是一种可拆卸的电伴热恒温加热保温罩。自控温电伴热在用于防冻、加热、恒温保温时，具有伴热管线温度均匀、不会过热、安全可靠、间歇操作时、升温启动快速、安装及运行费用低、安装维护简便、无环境污染、便于自动化管理、在选用电伴热的最长使用长度内任意剪断使用，重叠、交叉等使用、无须温控，其能自控、自限温度等优点。

        自控温电伴热，是在两根平行金属母线之间均匀地挤包一层PTC材料制成的芯带。电缆一端的两根母线与电源接通时，电流从一根母线横向流过PTC材料层到达另一根母线， PTC层就是连续并联在母线之间的电阻发热体，将电能转化成热能，对操作系统进行伴热保温。再配和柔体可拆卸材料组合而成的一种保温形式。 
        The heating and heat preservation cover is a detachable soft body energy-saving heat preservation heating form which converts electric energy into heat energy and is combined with a special process. It can be used in any shape on the parts of the equipment you need. It is a detachable electric heating constant temperature heating and heat preservation cover. Self-controlled temperature and electric heating is used for antifreeze, heating and constant temperature insulation. It has uniform temperature of heat tracing pipeline, no overheating, safe and reliable, intermittent operation, quick start of heating, low installation and operation cost, easy installation and maintenance, no Environmental pollution, easy to automate management, arbitrarily cut and use within the longest use length of electric heating, overlap, crossover, etc., without temperature control, it can control, self-limiting temperature and so on.

    Self-controlled temperature and heat tracing is a core tape made by uniformly encapsulating a layer of PTC material between two parallel metal bus bars. When two busbars at one end of the cable are connected to the power source, current flows from one busbar laterally through the PTC material layer to the other busbar. The PTC layer is a resistance heating body that is continuously connected in parallel between the busbars, converting electrical energy into heat energy. The operating system performs heat tracing. A combination of soft body and detachable material.
