我公司生产的电热带产品，通过了ISO-9001：2000质量体系认证，证号02005Q10097R0S；取得了国家防爆检测中心颁发的防爆证书，证号CJEx05.059U；公司产品由各种FDP恒功率、FDZ自限式、FDC串联型电热带、高温导线等品种。特殊规格可以定制、设计、加工。     自限温电伴热带主要用于各种管道、阀门和仪表的防冻保温。它能根据伴热温度调整其输出功率，这种自控温特性处处存在，即使在安装时交叉重叠，也不会产生过热，尤其适合用于较复杂管线场合的伴热，最高流体维持温度可达120℃。可用于工厂一区、二区爆炸性气体场合。自控温电热带额定电压为220V。        Self regulating heating cable is mainly used for frozen-prevention of pipe, valve and instruments. It can auto-adjust the power output according to the temperature. This self regulating characteristics occurs at every point along the length of cable, even in the overlapped point, the cable does not create hot spots or burnout. It is ideal for heating tracing in complicated heating environment. The maintenance temperature for fluid can reach 120℃. It can be used in division 1,2 hazardous (mixed gas) class locations. The set voltage is 220V.■产品结构     电源母线为二根平行的软铜线，在软铜线上包覆高分子半导体发热材料，母芯线通电后，各半导体发热材料发热，并随着温度的变化自动调整输出功率，而且可以根据使用情况任意剪接，即使很短也能发热。加强型适合于有腐蚀性的场合使用。        Power bus wire is two parallel soft copper wires. Macromolecule semi-conductor heating material wound around heating wire. The cable adjusts the output power according to the change of temperature after the power bus wire has power on and semi-conductor generates heater. The cable can also be cut in very short pieces and keep heating.
