Product Introduction:
This instrument utilizes Time Domain Reflectometry (TDR) to diagnose various faults in power cables, communication coaxial cables, telephone cables, control cables, mining cables, submarine cables, and more. It detects low-resistance, short-circuit, open-circuit, high-resistance leakage, and high-resistance flashover faults.

As a next-generation portable intelligent cable fault detection device, it integrates a high-performance industrial touchscreen computer, USB-interface data acquisition unit, high-capacity polymer battery, charging adapter, and accessories. Compact, lightweight, and user-friendly, it is designed for ease of use and portability.

Notably, the instrument excels in anti-electromagnetic interference and remains stable even under high-voltage impulse environments (tens of thousands of volts) without system crashes. Built with cutting-edge technology, precision engineering, and superior quality, it elevates cable fault detection to new heights, offering exceptional accuracy, intelligent operation, broad applicability, and reliable performance.

Key Features:

1.Detects faults in 35kV and below copper/aluminum power cables, coaxial communication cables, and telephone cables, including open-circuit, short-circuit, high-resistance flashover, and high-resistance leakage faults.

2.Supports multiple testing methods: Low-voltage pulse method, impulse high-voltage current sampling method, and DC high-voltage flashover method.

3.Powered by rechargeable polymer batteries or mains power. USB-connected sampling ensures complete isolation between operators, the instrument, and high-voltage environments, guaranteeing safety and anti-interference performance.

4.Advanced signal processing technology and Chinese UI provide clear waveform displays, simplifying fault analysis.

5.User-friendly Windows CE operating system for intuitive operation.

6.Expert online support: Email test waveforms for same-day analysis and guidance. Regular updates of fault waveform databases and case studies via email enhance user expertise.

7.Dual-track waveform comparison for precise analysis.

Technical Specifications:

1.Measurement Range: 4m to 40km

2.Accuracy:

≤1m error for distances <1km
