Huazheng HZDS-5B Underground Cable Identification Tester
Overview
A portable device designed for power cable engineers, integrating live/de-energized cable identification and AC current/voltage testing. Utilizes PSK technology + precision algorithms to ensure accurate target cable detection, preventing accidental cuts on live lines. Optimized for three-core armored cables.
Core Features
Live Cable Identification: Emits composite pulsed current signals for directional electromagnetic field detection.
De-energized Identification: Injects encoded pulsed current for safe identification.
Electrical Testing: Measures AC voltage (0-600V), current (0-5000A), and frequency (45-70Hz).
System Components
Transmitter
Function: Transmits four-frequency signals (625Hz/1562Hz/2500Hz/10kHz).
Design: Toolbox-style IP54-rated enclosure, withstands 200kg pressure.
Power: 11.1V Li-ion battery (8-hour runtime), auto-shutdown at low voltage.
Display: Real-time battery level and signal status on backlit LCD.
Transmitter Clamp
Specs: Φ120mm jaw for directional signal coupling (arrow indicates current flow).
Receiver
Function: Decodes signals, displays strength dynamically, marks target/non-target cables with √/× icons.
Design: 3.5-inch color screen, handheld, signal calibration supported.
Power: 7.4V Li-ion battery (6-hour runtime), USB rechargeable.
Flexible Rogowski Coil
Specs: Φ200mm jaw for non-contact measurement, fits irregular conductors.

Key Notes
Live Identification: Exclusive to three-core armored cables; clamp directions must align.
De-energized Mode: Never connect to live cables.
Calibration: Independent calibration required for different cables; frequency/gain locked post-calibration.
Safety: Withstands AC3700V (transmitter)/AC2000V (receiver).
Key Advantages
Efficiency: 1 detection/sec with dynamic visual feedback (√/× icons).
Versatility: Fits Φ200mm cables, supports long-range detection (0-10km in de-energized mode).
Protection: Low-battery alerts, 30-minute auto-shutdown, IP54 dust/water resistance.
