Overview
Power Cable Fault Pinpointer for Underground Cables GAOTek because of the extreme complexity of the power cable laying environment, pinpointing points has always been a critical step in cable fault testing. Even with an accurate rough side distance, it is difficult for us to locate quickly and accurately due to the influence of the external environment. The HZ-B cable fault precise locating instrument is a portable, ultra-quiet, visual impact discharge receiving precise locating instrument. It is specially used in conjunction with a high-voltage impact generator. It adopts leading background intelligent noise reduction and sound tracking new technologies to achieve Continuous optimization, perfect sound effect, record the characteristic sound of impact discharge and the signal that will be picked up at the scene to achieve comparison.
Features
- Ultra-quiet noise reduction processing, excellent sound quality of discharge sound, the background is quieter, monitor earphones are used to quickly and reliably locate the fault location
- Using ultra-quiet technology and BNR intelligent background noise reduction technology, you can adjust the impact discharge volume
- Molded design of a special self-falling ground sensor, and equipped with a soft pavement, hardened pavement, lawn sensor joint
- Reliable imported connectors are selected to ensure the purity of the sound, and the height-adjustable probe handle is humanized, which is very suitable
