Cable identification is designed for power cable engineers and cable workers to solve the technical problems of cable identification. Can be used to identify live cables and blackout cables. The user accurately identifies one of the target cables from multiple cables through the instrument to avoid missawing non target cables. When cable identification, 20 cables can be pre-rated at the transmitting end, and then received and identified at the far end, which greatly saves the calibration operation time of engineering personnel and improves the work efficiency. Cable identification success hit, non-target cable hit, can quickly and automatically identify the target cable. This function is realized by the signal transmitter, receiver, signal transmitting clamp, connecting test line and flexible caliper.
Signal transmitter: used for pipeline path detection and cable identification.The device can add identification signals to the target cable through direct connection output, caliper coupling, induction method, and so on. There are 13 different pulse signals of 250Hz, 577Hz, 640Hz, 1.28kHz, 2.56kHz, 3.20kHz, 4.09kHz, 8.19kHz, 10.2kHz, 33 kHz, 66 kHz, 82 kHz, and 197 kHz.The maximum signal output power is 15W, and 6 levels are adjustable, adapting to different application environments, making pipeline detection and cable identification more accurate and reliable.Instrument built-in large function rate can be charged with lithium battery, automatic impedance matching, automatic protection.The transmitter adopts the integrated special toolbox design, its box can withstand the pressure of about 200kg, the host 5 inch capacitor touch LCD display, real-time dynamic display signal output status and battery usage.
Transmitter Clamp：Suitable to caliper coupling method.The transmitting clamp couples the signal from the transmitter to the target cable, the jaw size is Φ125mm, the transmitting clamp is directional, and the emission signal flows from the direction indicated by the arrow on the transmitting clamp.
Receiver：For pipeline path detection and cable identification. Built-in shielding 3D antennas can effectively identify 13 different pulse-coded current signals of 250Hz, 577Hz, 640Hz, 1280Hz, 2.56kHz, 3.20kHz, 4.09kHz, 8.19kHz, 10.2kHz, 33 kHz, 66 kHz, 82 kHz and 197 kHz generated by the transmitter, and 50Hz and 60Hz power frequency signals and center frequencies of 33 kHz and 82 kHz.Use a 4.3-inch capacitive touch LCD screen, real-time dynamic display of 360 comprehensive pipeline path indication, depth, current and relative pipeline position.
Flexible current clamp：For the cable identification. The current clamp is a Roche coil, with excellent transient tracking ability, and can quickly identify the pulse width frequency signals generated by the transmitter. It is suitable for thick cables or irregularly shaped conductors.The inner diameter of the jaw is about 200mm, can clamp Φ200mm below the cable, do not need to disconnect the measured line, non-contact measurement, safe and fast.
Special note: When power outage cable identification: no access to the live cable. Live cable identification is only applicable to three-core armored cable. When identifying, the transmitting clamp and the receiving clamp should not be mixed, and the direction of the input signal should be consistent.
