Product Overview
The XHGG555 V2.0 Vehicle-Mounted Cable Diagnosis and Fault Location System is a fully customized, highly integrated mobile testing laboratory that consolidates 12 specialized cable testing and diagnostic functions into a single vehicle. It is engineered for rail transit and metro operators, urban underground cable networks, and municipal infrastructure maintenance teams that must locate and diagnose cable faults quickly across tunnels, stations, and hard-to-reach urban environments — without returning to base.
Unlike individual portable instruments that must be transported, set up, and operated separately, the XHGG555 provides a turnkey mobile platform where all systems are permanently installed, interconnected, and ready for immediate deployment. The platform can be customized to integrate transformer testing, circuit breaker testing, and other high-voltage diagnostic systems, and can be delivered as a complete vehicle or tailored for installation into your existing fleet vehicle.
🔍 Mobile Test Van vs Individual Portable Instruments: Individual cable fault locators, TDR units, surge generators, and bridge testers each serve a specific function but must be carried, connected, and calibrated separately at every job site — a time-consuming process that introduces setup variability. The XHGG555 integrates all 12 functions into a permanently installed, pre-calibrated system with a unified 15.6-inch touch-screen control interface. One vehicle, one deployment, one workflow — from fault pre-location to precise pin-pointing to final cable spiking, all completed on site without unpacking a single instrument case.
System Unit Composition — 12 Integrated Functions
- High-Voltage DC Pulse Generator: Causes cable fault point flashover discharge for testing initiation
- Traveling Wave Reflection (TDR): Rough measurement of all types of cable main insulation faults
- Acoustic-Magnetic Synchronization: Precise measurement and pin-pointing of cable main insulation faults
- Electromagnetic Induction Pathfinder: Accurately locates unknown cable paths and burial depths
- Bridge Method: Rough measurement of outer sheath faults and main insulation water ingress faults
- Step Voltage & Clamp Current Method: Precise outer sheath fault location
- Constant Power Burn-Through: Reduces ultra-high resistance faults to low resistance for easier location
- Encoding + Phase Method: Multi-cable identification among bundled cables
- Remote Control Cable Spiker: Final destructive verification — absolutely guarantees operator safety before cutting
- Ultra-Low Frequency (0.1Hz): Insulation withstand voltage test and dielectric loss test
- Ohm's Law Measurement: Cable loop resistance quality testing
- Essential Field Tools: Megohmmeter, measuring instruments, electrician tools — everything on board

Success Stories
XZH TEST has successfully deployed the XHGG555 vehicle-mounted system for power utilities and testing service providers. We can install the test system into a vehicle to provide you with a complete turnkey test van, or tailor the system for integration into your own vehicle based on interior space dimensions.
The system includes: high voltage pulse generator 8/16/32kV, ARC test cable fault pre-locator, high voltage burn-through bridge equipment, cable outer sheath fault locator, ultra-low frequency withstand voltage (80kV) dielectric loss test equipment, mobile cable fault accurate locator, cable path comprehensive tester, cable spiker, and generator — all permanently installed and interconnected.
Q1: Who is this vehicle-mounted system designed for?
The XHGG555 is designed for rail transit and metro operators, urban underground cable network maintenance teams, and municipal infrastructure crews that manage extensive cable systems across tunnels, stations, and densely built urban areas. A vehicle-mounted system eliminates the logistical burden of transporting, unpacking, and calibrating individual instruments at each job site — with all 12 testing functions permanently installed and pre-calibrated, crews arrive on site, connect to the cable, and begin testing immediately, minimizing track downtime and service disruption.
Q2: Can the XHGG555 be customized beyond cable fault testing?
Yes. The XHGG555 platform is built on a modular architecture that allows additional testing systems to be integrated beyond the core 12 cable fault diagnosis functions. Transformer comprehensive testing, circuit breaker analysis, partial discharge monitoring (via oscillation wave), dielectric loss measurement (via ultra-low frequency), and other high-voltage diagnostic systems can all be incorporated. Each module is independent — functionality can be added or removed without affecting existing systems. Contact XZH TEST with your specific requirements for a customized configuration.
Q3: What safety features protect operators during high-voltage testing?
The XHGG555 incorporates multiple layers of safety: F-U safety interlock monitors operating voltage connections; F-Ohm safety interlock monitors operational earth connections; door contact sensors automatically cut high voltage if the equipment compartment is accessed; an emergency stop button and lockout switch are on the front panel; a residual pressure indicator shows stored energy status; the 72kJ discharge system automatically grounds stored energy within 1 second of power loss; an isolation transformer (5kVA) separates the measurement circuit from mains; and RCD, overvoltage, and undervoltage protection monitor the power input continuously.
Q4: Do I need to purchase the vehicle or can the system be installed in my existing vehicle?
Both options are available. XZH TEST can provide a complete turnkey solution including the vehicle with all testing systems pre-installed, tested, and delivered ready for operation. Alternatively, if you have an existing fleet vehicle with suitable interior space, XZH TEST can design and install the testing system to fit your vehicle's specific dimensions. Contact us with your vehicle specifications for a tailored installation proposal.
Q5: What is the minimum order quantity and delivery time?
The minimum order quantity is 1 unit. Delivery time is 1-3 months depending on the level of customization required — standard cable fault diagnosis configurations ship faster, while highly customized multi-system integrations require additional engineering and assembly time. Each system is packaged for secure international transport. Annual supply capacity is 2,000 units. Payment terms are T/T. Contact XZH TEST for a detailed quotation based on your specific configuration requirements.
