電纜警示帶的購買事項

Purchase of cable warning tape

1.確保所購買的警示帶是否具有良好的絕緣、耐燃、耐寒、耐電壓、耐酸堿、耐溶劑等特性。

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.和一次性警示帶相比較是否具有不易拉斷、易清洗的簡包裝方式，集中聚合了盒裝警示帶的優勢。

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.警示帶的長度是否更容易施展，連接更為容易和方便，能否讓使用的地域無限的擴大。

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.

電纜警示帶使用事項

Usage of cable warning tape

1、檢查是否預留出了信號接入點，安裝方式是否正確。

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

2、檢查警示帶中的導電金屬絲是不是可以加載探測信號，有沒有信號泄漏的情況出現，以及是否設置了足夠的信號檢測井；

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、示蹤警示帶安裝好了之后，始端和末端是不是與地面隔離，信號檢測井內的警示帶是否進行了固定處理；

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、可探測警示帶中的導電金屬絲的直徑是不是滿足應用要求，金屬絲直徑太小容易被拉斷，直徑太大則會導致探測信號誤差增大，應該選取綜合效果***的直徑。探測信號容易出現的主要問題是信號連續性易受影響。

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.

原因有多種：

There are many reasons:

①可能在施工過程中操作失誤導致了警示帶內部的導線斷裂，造成了檢測短路

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

②警示帶的絕緣以及防水處理不夠過關，導致電線受潮影響探測

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導電金屬絲的直徑過大，造成電阻增大，信號衰減增大，影響探測的效果。

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