The core advantage of this device is the specialized underground electromagnetic shielding filtering module, which can effectively filter out the interference of underground metal pipelines, soil electromagnetic waves and other environmental factors on detection signals, solving the problem of large positioning errors of ordinary testers when detecting buried armored cables. It supports the superimposition of underground pipeline positioning data, which can directly display the relative position of the fault point and the underground pipeline, facilitating the accurate excavation of the fault point. The IP67 dustproof and waterproof structure can adapt to rainy and humid underground maintenance environments, and the host is drop-resistant, suitable for complex on-site conditions.
The host dimensions are 250mm × 140mm × 70mm, with a host weight of 2.1kg (including battery). The detection distance ranges from 0 to 30km, with a fault positioning accuracy of ±0.8m. It is specially designed for armored underground cables, supporting the detection of various types of armored cables including steel tape armored cables and steel wire armored cables. The operating voltage is DC 7.4V, with a charging specification of 5V/2A. The storage temperature ranges from -20℃ to 60℃, with a 4.3-inch TFT color screen, a signal sampling frequency of 110MHz, a protection rating of IP67, and supports underground pipeline positioning superimposition function.
This tester is mainly applicable to urban underground pipe network cable maintenance, buried power cable fault troubleshooting, communication cable buried line maintenance, railway signal cable underground testing and other scenarios. It can accurately locate the fault point of underground armored cables, reduce the scope of excavation, and improve the efficiency of underground cable fault maintenance.
