Customizable Shielded HV Cable Thumper XHHV535-4TS Three Voltage Ranges 8 16 32kV for Fault Locating Contractors

The XHHV535-4TS is built for organizations that require flexibility in their cable fault locating equipment. Whether you are a contractor managing diverse voltage classes across your service territory, a utility standardizing its fleet with custom-configured surge generators, or a distributor seeking OEM-branded equipment for your market — the 4TS adapts to your requirements.

The XHHV535-4TS features a fully shielded high-voltage compartment that isolates the DC power source, energy storage capacitor, and discharge sphere assembly within an enclosed metal housing. This design serves three critical purposes for field and industrial operations:

• Operator Safety: The shielded enclosure prevents accidental contact with energized components during operation. All high-voltage paths are contained within grounded metal barriers — exceeding IEC 61010-1 safety requirements for high-voltage test equipment
• Electromagnetic Compatibility: The shielded construction minimizes radiated EMI during surge discharge events, protecting sensitive co-located instruments such as TDR cable testers, acoustic-magnetic pinpointers, and communication equipment from electromagnetic interference
• Environmental Resilience: The enclosed design protects internal components from dust, moisture, and mechanical impact during transport and on-site deployment — essential for field teams operating in substations, trenches, and outdoor cable vaults

The XHHV535-4TS is engineered as a customizable platform. XZH TEST supports OEM and ODM orders with the following configurability:

Unlike modular surge generator setups that require separate DC supply, capacitor bank, and discharge sphere modules interconnected by high-voltage cables on-site, the XHHV535-4TS integrates all three subsystems into one shielded enclosure:

• DC High-Voltage Power Source: Built-in rectifier and step-up transformer, providing continuously adjustable DC output within each voltage range
• Energy Storage Capacitor Bank: Three internal capacitors (4/16/64μF) automatically selected by the voltage range switch — no external capacitor connections or manual reconfiguration
• Discharge Sphere Assembly: Precision-machined tungsten-alloy discharge spheres with adjustable gap, enclosed within the shielded compartment for controlled, repeatable surge characteristics

1. Pre-Locate with TDR: Use a TDR cable fault locator (such as XZH TEST 502 series) to estimate the fault distance. The 4TS's internal waveform sampling module provides a clean trigger signal for TDR acquisition
2. Select Voltage Range: Choose 8kV, 16kV, or 32kV based on the cable's voltage rating — rotation of the front-panel selector instantly reconfigures the internal capacitor bank
3. Zero-Check and Start: Verify zero-position indicator is illuminated, press Start, then increase voltage to the desired surge level
4. Pinpoint with Acoustic-Magnetic Method: The 4TS delivers controlled 2048J surge discharges at ~4-second intervals. Use an acoustic-magnetic pinpointer (such as XZH TEST XHDD503) at the estimated fault location to capture discharge sound and electromagnetic signals
5. Mark and Excavate: Once the fault point is acoustically confirmed, mark the surface, de-energize the 4TS, and proceed with targeted excavation
