Underground cable detector

Item number: ZH5111
Product Introduction
Underground cable detectorCapable of underground cable detection: searching and tracing the path of running cables, identifying and judging running cables, conducting underground cable surveys during construction, identifying grounding faults in buried cables, and accurately determining cable depth using various methods. It mainly solves the comprehensive problems of finding the path of underground cables, detecting cable burial depth, detecting cable to ground faults, and identifying cables generated during cable relocation and construction, which are increasingly common in production, power supply, and construction.
Underground cable detectorCharacteristics:
1. Multiple functions such as cable routing, cable identification, and measuring cable grounding faults.
2. Simple operation methods can be mastered through Chinese menu training.
3. Configure nickel hydrogen rechargeable batteries and rechargeable batteries, and the test can be completed with mains power.
Search for cable paths during operation:
It can easily solve the problems of searching for live cable paths and measuring cable burial depth. The process is to clamp the transmission coupling clamp onto the cable to be tested, and the transmitter generates a coupling signal on the target cable through the coupling clamp. The signal applied by the transmitter can be received along the cable path.
The instrument receiver can detect the 50Hz frequency signal of the running cable when used alone. This working method is very useful for distinguishing between live and non live cables, as well as detecting power cables before construction. In this method, a transmitter is required.
Blind testing of underground cables:
In some cases, such as cable construction or cable movement, it is impossible for the operator to approach the cable for direct connection or use coupling clamps. In this case, the built-in induction antenna of the transmitter can be used to transmit output signals and sense the signals onto the underground cable being tested for positioning and exploration.
Identification of operating cables:
Clamp the transmitter onto the cable using the transmission coupling clamp, and connect the receiver to the exposed end of the cable using the reception coupling clamp and clamp it onto the tested cable. At this point, the signal size can be used to determine which one is the signal cable. (This method requires an additional receiver clamp). When the receiver is used in conjunction with the receiver clamp and transmitter, it can be used for identifying the live state of cables.
Search for faults in buried cables:
Underground cable detectorThe step voltage method can be applied to determine cable faults in buried cables with a ground resistance of less than 2M Ω; The signal strength method can also be used to determine cable open circuit and short circuit faults, as well as cable phase to phase short circuit faults. The underground cable detector has changed the concept of cable fault location. It is a high-voltage testing device that uses AC power, analyzes waveforms, and has simple and clear wiring, making it easy to use at a glance.
