In fact, the quality of electric heating tubes depends on the following six factors:

1. Compressive strength of electric heating tube electrical equipment: The factors that harm the compressive strength of electric heating tube electrical equipment mainly include the thickness of the cable sheath, the material quality of the cable sheath, the length of the electric heating tube, the rough half diameter, and the number of bumps. The thermal compression resistance of the electric heating tube can generally guarantee 2000V, one second, and a penetration current of 0.5mA.

2. Insulation layer of electric heating tube: The main hazard to the insulation layer of electric heating tube is the sealing technology of the electric heating tube. It can generally guarantee above 1000 megaohms.

3. The leakage current of electric heating tubes is mainly related to the temperature during the application of electric heating tubes, the operating voltage of electric heating tubes, and the length of heating of electric heating tubes. A key verification of the overall goal regarding high-temperature electric heating tubes.

4. The accuracy of the output power of the electric heating tube is mainly related to the quality of the resistance wire and the technical strength of the manufacturing factory. Before mass production, it is necessary to conduct temperature coefficient tests to determine the qualified output power and operating scale of thermal resistors.

5. The lifespan of electric heating tubes: In addition to being related to the quality of the resistance wire, the lifespan of electric heating tubes is also related to factors such as the quality of magnesium oxide powder and the selection of resistance wire diameter. Regarding high-temperature electric heating tubes, make electric heating tubes with external loads below 8W/CM2. When selecting the diameter of the resistance wire, it is necessary to transfer the external load of the resistance wire to meet the required lifespan.

6. Corrosion resistance of electric heating tubes: doubts often encountered between water heating electric heating tubes and baking string electric heating tubes. In addition to effective material selection, it is also related to the heat treatment process of the electric heating tube and the appearance of the electric heating tube.
