FAQ – Power Cable Identifier
Q1: What is a Power Cable Identifier used for?
A: It is designed to distinguish the target de-energized cable safely among a bundle of multiple laid cables. Widely applied in cable renovation, relocation, routine maintenance and cable fault troubleshooting for substations, urban power grids and industrial plants.
Q2: What core technology does this cable identifier adopt?
A: It applies intermittent pulse modulation signals. The signal generator injects directional pulsating current into the selected cable. The detection clamp captures the magnetic field generated by the current, and the display unit judges the correct cable via signal direction and amplitude. Closed-loop induction measurement guarantees no signal distortion.
Q3: Can this device identify live energized power cables?
A: No. This model is specially used for de-energized offline cables only. It is forbidden to connect the signal output terminal to live cables to avoid equipment damage and safety accidents.
Q4: What types of cables are compatible with the identifier?
A: It works for all common low & medium voltage power cables, including cables laid on cable trays, cable bridges, underground trenches and direct buried power cables.
Q5: What is the maximum detectable cable length?
A: There is no strict length limit. It can accurately recognize cables ranging from dozens of meters up to several kilometers under normal working conditions.
Q6: Why does the equipment adopt passive detection clamp and passive display?
A: The passive design requires no built-in batteries for the clamp and display unit. It effectively reduces failure rates, avoids battery aging issues, delivers stable anti-interference performance and adapts to complex electromagnetic field construction sites.
Q7: Is the instrument resistant to short circuit?
A: Yes. The signal generator features stable high output power with built-in short-circuit protection circuits. It can work safely even if the output terminals are accidentally short-circuited.
Q8: What is the working temperature range of the whole set?
A: Ambient working temperature ranges from -20℃ to +50℃, suitable for cold northern areas and high-temperature tropical regions.
Q9: How to confirm I have picked out the correct cable accurately?
A: After injecting the signal, only the target cable will show consistent signal direction and obvious signal amplitude on the display. All other bundled cables will display weak or reversed signals for easy differentiation.
Q10: Is professional training required before operation?
A: No complicated professional knowledge is needed. The operation steps are simplified, and operators can master the whole testing process quickly following the user manual.
Q11: What accessories are included in the standard complete set?
A: Standard packing contains signal generator, detection clamp, signal display unit, power cord, output cables, signal wire, user manual, calibration certificate, aluminum carrying case, qualification certificate and warranty card.
Q12: How long is the product warranty period?
A: We provide 12-month global warranty for the main unit. Lifelong paid technical support and component maintenance are available after the warranty expires.
Q13: Can the equipment pass international acceptance inspection for overseas power projects?
A: Each unit is strictly tested before delivery and equipped with official factory calibration certificates, which meets the acceptance standards of most overseas electrical engineering projects.
