Kas ir iemesls par the short circuit or open circuit of the single-head electric heating tube?

What is the reason for the short circuit or open circuit of the single-head electric heating tube?
1. The distance between the two holes of the lead wire is too close, causing the single-head electric heating tube to short circuit. 2. The position of the heating area of the electric heating tube has been moved to the lead-out port and exposed to the air. 3. Too high temperature is a sufficient and necessary condition for short circuit caused by the rated voltage of the second lead wire. 4. When in use, the aperture of the mold hole is horn-shaped. This is due to the defect of the module drilling process, which affects the heat conduction. 5. The nozzle of the warhead electric heating tube has a loose powder phenomenon at the end of the lead wire, which affects heat conduction and air breakdown, and causes a short circuit of the single-head electric heating tube. 6. The distance between the inferior sealing silica gel and the first circle of screws at the root of the lead wire is too close. 7. Using iron, chromium and aluminum as the excessive resistivity of the lead wire to increase the temperature of the lead wire of the electric heating tube and cause an accident.Single-head electric heating tubes have these uses
