In the field of cable laying and fault detection, common laying methods include direct burial, pipe laying, trench or tunnel laying, and bracket or bridge laying. Each of these methods has its own characteristics and challenges when finding cable faults.
Direct burial method: It is the basic cable laying method, requiring a burial depth of about 800mm, but due to various reasons, some cables may be buried deeper, such as 3-4 meters, which increases the difficulty of fault detection, mainly reflected in the accurate positioning of the cable.
Direct burial method through pipe: It is used when the cable passes through roads, railways or buildings. The cable needs to pass through iron pipes, cement pipes or PVC pipes. Although this method protects the cable, the fault location is more complicated, especially at the cable pipe, which requires special techniques for accurate positioning.
Trench or tunnel laying method: It makes cable fault finding relatively easy, and its main advantage lies in the accurate positioning of cable faults. This method is generally used in cases where the process is complex and the environmental requirements are high, making the cable easier to maintain and detect.
Bracket or bridge laying method: Similar to trench or tunnel laying, when a cable fails, coarse measurement technology is particularly important to quickly find the approximate location of the fault. In addition, this method is more convenient for maintenance and detection because the cable is exposed indoors or on a specific path.
In general, various laying methods have their own advantages and disadvantages in cable fault detection, and it is crucial to choose the right laying method and detection technology. Complex lines and burial depths directly affect the difficulty of fault location, and professional fault detection equipment and rich experience of technicians are especially required.
