Product functions
1. Accurate identification of de-energized cables
For scenarios where multiple cables are laid in parallel in cable trenches, cable trays, distribution cabinets, and construction sites, the UHV-521 can quickly identify the target cable among many similar-looking cables by transmitting characteristic signals, reducing the risk of misoperation.
2. Live cable identification
The device is equipped with a dedicated transmitting clamp that enables cable identification under live conditions through clamp coupling, making the device capable of identifying both de-energized and energized cables.
This function is particularly suitable for field environments where power outage is inconvenient or where live-line identification is required.
3. Multi-parameter comprehensive discrimination
The receiver host features a color LCD screen that simultaneously displays identification signal parameters including:
Signal direction
Signal amplitude
신호 간격
Comprehensive judgment based on multiple parameters improves the reliability of target cable identification.
In addition, the device can retain multiple signals on the time axis and perform judgment based on continuous valid signals, thereby reducing misjudgment caused by single signal fluctuations.
4. Flexible measurement coil
The device uses a flexible measurement coil, which solves the problem of traditional receiving clamps being difficult to clamp onto target cables in densely packed, crossed, or overlapping cable environments.
For sites with compact cable arrangements and limited space, the flexible measurement coil improves operational flexibility and adaptability.
5. Multi-purpose design
The device is also equipped with a transmitting clamp, enabling clamp-coupling live cable identification, so that a single set of equipment can cover cable identification needs under different conditions, improving equipment utilization and on-site work efficiency.
Product Characteristics
1. High-Energy Lithium Battery Power: The transmitting host is powered by a high-energy lithium battery, eliminating the need for on-site 220V power access. It features compact design, low power consumption, long battery life, and a multi-level power indicator.
2. Color LCD Display: The receiving host adopts a color LCD display with accurate power indication. It synchronously displays signal direction, amplitude, and interval as effective judgment criteria, while retaining multiple signals on the time axis for more accurate cable identification through continuous valid signals.
3. Flexible Measurement Coil: Utilizes a flexible measurement coil for cable identification, solving the problem of crowded and overlapped cables in power field environments where traditional receiver calipers cannot be inserted into the target cable, thus enabling identification in such scenarios.
4. Transmitting Calipers: Equipped with transmitting calipers to achieve live identification function through caliper coupling, enabling multi-purpose use of a single instrument.
5. ABS High-Strength Protective Case: Provides effective protection for the instrument, while facilitating convenient transportation and adapting to harsh on-site environments.

FAQ about Live line Cable Identification Device
Q:Why is live cable identification necessary?
A:Traditional cable identification methods may require power interruption or direct access to the cable. A live cable identification instrument allows technicians to identify cables without shutting down the electrical system, helping reduce downtime and improve work efficiency.
Q: What are the typical applications of the Live Cable Identification Instrument?
A: This type of equipment is widely used in substations, distribution rooms, industrial plants, building power distribution systems, and underground cable networks. For example, it can be used to confirm the target cable before cable retrofitting or replacement. In environments where multiple circuits are laid in parallel, it can also assist staff in quickly distinguishing different lines, thereby improving on-site work efficiency.
Q: When using a Live Cable Identification Instrument, what factors may affect the identification performance?
A: Identification performance is typically related to cable length, laying method, number of parallel cables, grounding conditions, line configuration, and on-site electromagnetic interference. Signal coupling or interference may occur when cables are in close proximity or when complex circuits are present. Therefore, when selecting equipment, attention should be paid to its identification range, signal detection sensitivity, anti-interference capability, and applicable voltage range, with evaluation based on the actual grid configuration.
Q: What technical parameters should be focused on when selecting a Live Cable Identification Instrument?
A: In addition to the applicable voltage level, attention should also be paid to the identification method, signal frequency or signal characteristics, detection sensitivity, maximum identification range, anti-interference performance, supported cable types, transmitter and receiver unit configuration, and battery life. If the equipment is to be used for long-term field engineering, portability, protection rating, operating interface, data recording capabilities, as well as calibration and after-sales service should also be considered.
