Difficult problems and precautions when using single-head heating tube

1. Before installation, the dedicated heating tube should be carefully read in related articles to understand the main parameters to avoid damage.

2. The hot part of the single-head heating tube should be exposed to the heating material to prevent slow heating release, exceeding the allowable heating temperature and damaging the heating tube. In addition, part of the wiring should be exposed to the cable sheath of the electric heater or outside the electric heater to prevent overheating and damage.

3. When the power supply is introduced, the working voltage shall not exceed 10% of the rated voltage marked on each heating tube. If the rated current is lower than the rated current, the power generated by the single-head heating tube will be reduced.

4. The outlet of the single-head heating tube group should be kept clean and dry, which will in turn reduce the volume resistivity and be infiltrated by short-circuit faults. If the environment is corrosive, flammable, combustible, explosive or other liquid or gas environment, the cable sheath sealing equipment should be used to strictly protect the outlet part of the heating tube group to avoid safety accidents.
