High Voltage Surge Generator 0-32kV 2048J Impulse Discharge for 35kV Power Cable Fault Detection| XHHV535-4Z

Underground Power Cable Networks

Impulse discharge for 35kV and below cable fault pre-location, combined with TDR and acoustic magnetic synchronization for accurate fault pinpointing in urban distribution grids.

Industrial Plants & Substations

DC withstand voltage testing of transformers, switchgear, cables and other high-voltage electrical equipment during commissioning and routine maintenance.

Railway & Transit Systems

Fault location on signaling and traction power cables. The 35kg portable design enables fast deployment along rail corridors with limited vehicle access.

Renewable Energy Projects

Testing medium-voltage collector cables in solar farms and wind plants. Short-circuit tolerant design handles challenging field environments.

Q: What is the difference between DC withstand voltage mode and impulse discharge mode?

DC withstand voltage mode provides continuous DC high voltage output for insulation testing of transformers, switchgear and other electrical apparatus. Impulse discharge mode generates high-energy pulse signals specifically designed for cable fault flashover testing and acoustic-magnetic synchronization fault pinpointing.

Q: What is the maximum cable length this generator can test?

The effective testing range depends on cable type, fault resistance and site conditions. For 35kV power cables, the XHHV535-4Z typically achieves reliable fault location on cables up to 10km when paired with a TDR cable fault locator and acoustic magnetic pinpointer for final precise positioning.

Q: Does this equipment require special operator training?

The XHHV535-4Z features intuitive panel controls with clear labeling and built-in safety interlocks, making operation straightforward. We recommend operators have basic high-voltage safety training. A comprehensive user manual is included with every unit, and remote technical support is available from our engineering team.

Q: What safety certifications does the XHHV535-4Z hold?

The equipment is CE certified and manufactured under ISO 9001:2015 quality management system. It fully complies with DL/T846-2016 General Technical Conditions for High Voltage Test Equipment and DL/T474-2017 Implementation Guidelines for Field Insulation Test. Each unit undergoes factory testing before shipment.

Q: Can the output voltage and discharge energy be customized?

Yes. XZH TEST provides customization of voltage ranges, capacitor bank capacity, discharge intervals and other parameters. Whether you need higher voltage ratings for specific applications or integrated solutions combining multiple test functions, our engineering team can configure a solution that matches your field requirements.

Q: What is the standard warranty and after-sales support?

Standard warranty is 12 months from delivery, covering manufacturing defects. Extended warranty plans are available. We provide lifetime technical support, spare parts supply, and optional on-site commissioning and training services. Most inquiries receive a response within 24 hours.
