The new method of electric heating film derives from the existing technology of resistance heating of oil tank. In general, resistance heat is with the method of Plug-in oil tank. As a kind of material with good scalability and flexibility, electric heating film can be installed with several ways, which will be introduced detailed. Heating oil can volatilize inflammable and explosive gas easily, so the associated electrical equipment must accord strict safety standards for fire, explosion-proof and anti-static. In our country, the design of electrical equipment accords There are some test data about the heating efficiency of electric heating film. Comparing with a variety of heating equipment, we can get that electric heating film can save more energy and be widely used in industrial life.
