A list,
Z Y DY-900 live cable identification instrument is designed for power cable engineers and cable workers to solve the technical problems of cable identification. Users can accurately identify one target cable from multiple cables through the instrument to avoid serious accidents caused by missawing live cables. Cable identification starts with operations at both ends of the cable. Ensure that the double numbers at both ends of the cable are accurate. The instrument design uses P SK technology, combined with precise algorithm. This product has the functions of live cable identification, power failure cable identification, AC current test, AC voltage test at the same time. It is composed of a transmitter, a transmitting current clamp, a receiver, a receiving flexible current clamp, etc. When identifying live cable, it can pre-calibrate 10 cables at the transmitting end, and then receive and identify at the remote end.
