How to use the cable warning tape below

1、检查是否预留出了信号接入点，安装方式是否正确。

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

2、检查警示带中的导电金属丝是不是可以加载探测信号，有没有信号泄漏的情况出现，以及是否设置了足够的信号检测井；

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

3、示踪警示带安装好了之后，始端和末端是不是与地面隔离，信号检测井内的警示带是否进行了固定处理；

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、可探测警示带中的导电金属丝的直径是不是满足应用要求，金属丝直径太小容易被拉断， 直径太大则会导致探测信号误差增大， 应该选取综合效果的直径。探测信号容易出现的主要问题是信号连续性易受影响。

4. Whether the diameter of the conductive metal wire in the warning tape can meet the application requirements can be detected. If the diameter of the metal wire is too small, it is easy to be broken. If the diameter is too large, the detection signal error will increase. Therefore, the diameter with comprehensive effect should be selected. The main problem of detection signal is that the signal continuity is easily affected.

原因有多种：

There are many reasons:

①可能在施工过程中操作失误导致了警示带内部的导线断裂，造成了检测短路

① It is possible that the misoperation during the construction led to the breakage of the wire inside the warning tape, resulting in the detection short circuit

② 警示带的绝缘以及防水处理不够过关，导致电线受潮影响探测

② The insulation and waterproof treatment of the warning tape are not qualified enough, causing the wire to be affected by moisture and affecting the detection

③ 导电金属丝的直径过大，造成电阻增大，信号衰减增大，影响探测的效果。

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