XHGG502 Cable Fault Tester: Eight-pulse method subverts high-resistance detection
Equipped with an industrial-grade 12.1-inch touch screen and intelligent algorithm, XHGG502 uses the "eight-pulse method" technology to simplify the high-resistance fault waveform into a low-voltage short-circuit waveform, achieving one-key distance measurement (error ≤±0.5%). It supports 68km ultra-long distance measurement and 400MHz high-speed sampling. The built-in battery meets the requirements of power supply-free environment operation and is suitable for 6kV to 66kV full-voltage grade cables. It is especially suitable for long-distance scenarios such as transnational power grids and offshore energy. It is pre-installed with a multi-language system and GPS track recording function, making it the core equipment of a power grid transformation project in a Southeast Asian country, and improving the troubleshooting efficiency by 70%.
XHHV535-4TS high-voltage pulse generator: 2048J energy output, double upgrade of safety and performance
The device integrates 32kV high-voltage output, three-speed capacitance adjustment and automatic discharge protection. A single machine can complete impulse discharge and withstand voltage test, and is suitable for flashover high-resistance fault detection. The cart design, DC withstand voltage function and multi-country voltage compatibility (AC 220V±10%) enable it to perform well in harsh scenarios such as African mining areas and South American oil bases. Overseas users feedback: "Its visual pointer meter and automatic protection mechanism greatly reduce the risk of high-voltage operations."
XHDD503C cable fault locator: acoustic and magnetic synchronous locking millimeter-level error
As the world's first acoustic and magnetic synchronous locator, XHDD503C integrates vibration pickup and electromagnetic induction technology, triggers the discharge of the fault point through high-voltage pulses, accurately captures sound waves and magnetic field signals, and intelligently calculates the time difference to achieve millimeter-level positioning of the fault point (accuracy ≤ 0.1m). Its 5-inch high-brightness touch screen, IP65 waterproof design and multi-level noise reduction function can adapt to complex environments such as underground pipe networks, high temperature and high humidity, and support a variety of cable types around the world (including power, communication cables and high-resistance faults), in line with the international DL/T 849.2-2019 standard, and is called "GPS for underground cables" by overseas engineers.
