Purchase of cable warning tape

1. Ensure whether the warning tape purchased has good insulation, fire resistance, cold resistance, voltage resistance, acid and alkali resistance, solvent resistance and other characteristics.

2. Compared with disposable warning tapes, whether it has a simple packaging method that is not easy to break and easy to clean, which centralizes the advantages of boxed warning tapes.

3. Whether the length of the warning tape is easier to display, the connection is easier and convenient, and whether the area of use can be infinitely expanded.

Usage of cable warning tape

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

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

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

4. Can the diameter of the conductive wire in the warning tape meet the application requirements? If the diameter of the wire is too small, it is easy to be broken, and if the diameter is too large, it will increase the error of the detection signal, so the diameter of * * * with comprehensive effect should be selected. The main problem of detection signal is that the signal continuity is easily affected.

There are many reasons:

① The wire inside the warning tape may be broken due to misoperation during construction, resulting in detection short circuit

② The insulation and waterproof treatment of the warning tape are not qualified enough, resulting in the wire being affected by moisture and affecting the detection

③ The diameter of the conductive wire is too large, resulting in the increase of resistance and signal attenuation, which affects the detection effect.
