120kg Trolley High Voltage Surge Generator 2048J 3-Speed Capacitor for 35kV Cable Fault Testing

The XHHV535-4TS is a lab-grade trolley high-voltage surge generator engineered for high-precision cable fault testing and DC withstand voltage analysis at voltage levels up to 35kV. Featuring a unique 3-speed capacitor system (4μF/32kV, 16μF/16kV, 64μF/8kV), it delivers up to 2048J discharge energy with adjustable output levels for precise test waveform acquisition. Built on a heavy-duty trolley chassis at 120kg, the unit provides the stability and durability required in permanent testing facilities.

This device integrates a high-voltage DC source, energy storage capacitor, discharge ball gap, automatic discharge device, and voltage level switching mechanism into a single cart-type platform. Tri-mode operation—DC withstand voltage, single impulse discharge, and periodic cycle discharge—enables comprehensive cable fault characterization. A dedicated communication socket interfaces with cable fault testers for high-voltage flashover waveform sampling. Rated IP54, with zero-start protection and automatic residual voltage discharge after shutdown.

• 3-speed capacitor system: 4μF/32kV, 16μF/16kV, 64μF/8kV with manual voltage level switching
• Tri-mode operation: DC withstand (0–32kV, 0–20A), single impulse, periodic cycle discharge
• High-current burn capability: 60mA/32kV, 120mA/16kV, 240mA/8kV for fault conditioning and arc path clearing
• Communication socket with dual-Q line interface for synchronized waveform sampling with cable fault testers
• Zero-start protection prevents high-voltage output unless voltage knob is at zero position
• Auto-discharge: residual high voltage on the device and cable under test is automatically discharged after stop
• Over-voltage, over-current, and over-heating automatic protection
• IP54 protection rating—suitable for industrial and field environments with dust and splash protection
• Real-time analog metering: high-voltage side voltage and current indication with 1.5-level accuracy

The XHHV535-4TS trolley platform is designed for permanent testing laboratories, cable manufacturer QC departments, third-party testing and certification agencies, and utility training centers—environments where equipment stays in a fixed location and where maximum energy output, multi-level testing capability, and instrument-grade waveform acquisition are valued over portability. The 3-speed capacitor system enables voltage-matched testing across low, medium, and high voltage cable ratings. The trolley form factor with IP54 protection makes it suitable for semi-permanent workshop installations and sheltered outdoor test bays. For field-portable applications, refer to the XHHV535-2L (25kg) or XHHV535-4Z (35kg) models.
