Gas warning tape plays a warning role in our life to ensure the personal safety of people around. In places where people are not allowed to enter, the warning tape preventing "non internal personnel are not allowed to enter" can ensure the safety of internal equipment and the safety of external personnel.

Gas warning tape is mainly composed of gas warning tape box, megger, warning tape, adjusting knob and metal card. Gas warning tape is mainly used for outdoor and indoor work in open high-voltage places, or for temporary isolation of adjacent operating equipment.

The width of the warning tape shall be about 5 cm, and the tape shall be printed with words such as "stop, high pressure danger", with an interval of one meter. The length of the warning tape shall be designed according to the actual use, generally 20 m/plate, 30 m/plate and 50 m/plate.

Each warning tape that has been delivered shall be marked with permanent and obvious signs; The name and specification of the warning tape, as well as the name and model of the manufacturer, including the main performance, should be clearly marked. And the date of manufacture shall also be marked on the plate.

How to use gas warning tape

1. Check whether the signal access point is reserved and whether the installation method is correct.

2. Check whether the conductive metal wire in the warning tape can load the detection signal, whether there is signal leakage, and whether there are enough signal detection wells;

3. After the tracer warning tape is installed, whether the start and end are isolated from the ground, and whether the warning tape in the signal detection well is fixed;

4. Whether the diameter of the conductive metal wire in the detectable warning tape meets the application requirements. If the diameter of the metal wire is too small, it is easy to break. If the diameter is too large, it will lead to increased detection signal error. Therefore, the diameter with good comprehensive effect should be selected. The main problem of detection signal is that the signal continuity is easily affected. There are many reasons:

① It is possible that the wire inside the warning tape was broken due to the operation error during the construction, resulting in the detection short circuit; ② The insulation and waterproof treatment of the warning tape are not up to standard, which causes the wire to be affected by moisture and affects the detection; ③ The diameter of the conductive metal wire is too large, which causes the resistance to increase and the signal attenuation to increase, affecting the detection effect.
