High Efficiency of Electrothermal Conversion Mineral Insulated Heating Element possesses good property on high efficiency of electrothermo conversion compared to other heating solutions.
Using the principle of the thermal effect of electrical current (Joule-Lenz law), the pure resistance heats up, converting almost 100% electric energy into heat energy.
Mineral Insulated Heating Element for Chemical Industry Heating or Heat Trace is to be designed based on selection of mineral insulated heating cable which is prefabricated in the manufacturer's workshop into a heating element that can be directly connected to the power supply. It is usually composed of heating cables, cold and hot joints, cold end cables, terminals, tail ends and lead wires, etc. There are the following types can be selected from including type A, Type B, Type C, Type D, Type E, Type F and Type G structures. Among them, Type A, B and C are only suitable for single-core heating cable, while type D, E, F and G are only suitable for double-core heating cable.
Common structure of the heating cable for the heating element is of single core and two core, while the customization can be according to clients’ needs to design and provide MI heating cable of three core or more.
