What are the reasons for the burnout of the lead wire of the single-head electric heating tube?

Single-head electric heating tubes are widely used in various fields due to their small size, fast heating, uniform temperature, simple and convenient disassembly and maintenance. During use, the heater may have a burnt lead, which may cause the heating tube to fail to work normally and even bring safety risks.
The common main reasons for the burnt lead of the electric heating tube are as follows:
1. Overload:
When the actual working voltage or power of the electric heating tube exceeds its design range, the current and power load of the heater will increase, causing the lead temperature to rise and eventually the lead to burn out. 2. Poor contact of the lead:
If the internal electrode and lead of the electric heating tube are not in close contact, poor contact may occur. When current passes through, it may cause overheating and burnout. 3. Unsuitable working environment:
If the working environment temperature of the electric heating tube is too high or the humidity is too high, the insulation material inside the electric heating tube may be damaged by moisture absorption, the insulation resistance will be reduced, and short circuits and other problems may occur, causing the lead to burn out. Solution to burnout of the lead of the electric heating tube:
Reconnect the lead:
If the lead of the heater is broken due to poor contact and no other problems occur, the lead can be removed and reconnected for normal use (only for external wiring type heating tubes). Replace the heating tube:
If the lead of the heating tube has been completely burned out or the heater has other damage, we recommend replacing it with a new one. When repairing or replacing electric heating tubes, pay attention to safety and avoid accidents. It needs to be repaired and replaced by professionals, or handled under the guidance of professionals. To prevent the lead from burning out, please ensure that the heater operates within the rated voltage and power range, check the status of the equipment regularly, and handle it in time
