How to Properly Resolve Interference Issues of Electric Heating Tubes?

Electric heating tubes are electrical components designed to convert electric energy into thermal energy. They demand high operational stability and comply with stringent industry application standards. Nevertheless, many users encounter interference problems during operation. Lilin Electric Heating has summarized three practical solutions for your reference.

1.Isolation Method

Install the electric heating tube in a suspended state to avoid contact with furnace refractory bricks. Use insulating materials to separate the tube from supports. This approach effectively prevents interference caused by high-temperature electric leakage.

2.Shielding Method

Run the compensation wires of the heating tube through iron pipes or other metal shielding materials to block electromagnetic and high-voltage electric field interference. Ensure reliable grounding for pipes and shields, and twist the compensation wires tightly during installation.

3.Grounding Method

Two mainstream grounding modes are available. The first is reference terminal grounding: connect one end of the heating tube or compensation wire output to ground via a large-capacity capacitor, with higher capacitance preferred. The second is measuring terminal grounding: lead a metal wire from the measuring terminal to ground. This method delivers excellent protection against high-temperature leakage interference.

Heating wires serve as core components of electric heating tubes. When purchasing products, select tubes equipped with high-temperature resistant heating wires that cause no damage to electrodes. This measure mitigates interference risks, ensures safe operation, and improves working efficiency.
