Digital Portable cable fault location 0-60kV 600mA High Voltage Burn Through Bridge

The XHSC-60Q Digital Portable High Voltage Burn Through Bridge is a self-contained, field-deployable diagnostic instrument that integrates 60kV burn-through and 600mA intelligent bridge capabilities into one portable platform. Purpose-built for power distribution utility field crews, emergency fault response teams, and independent electrical testing service contractors, it enables rapid deployment to fault sites — converting high-resistance cable faults into precisely locatable low-resistance conditions without requiring a full diagnostic laboratory on site.

• Integrated Dual-Mode Design: Combines 60kV burn-through (600mA) and intelligent bridge (600mA) in a single unit — eliminating the need to transport and connect multiple separate instruments to the field.
• Portable & Rugged Construction: Packaged in a pull-rod carrying case with dimensions 30cm × 46cm × 50cm. Designed for vehicle transport and rapid setup at roadside cable pits, substation yards, and urban excavation sites.
• 60kV / 600mA High-Power Burn-Through: Sufficient output to carbonize high-resistance faults (up to tens of kΩ) on 35kV and below cables within minutes, converting them to measurable low-resistance states.
• 600mA Intelligent Bridge: Delivers precise fault distance measurement using the Murray loop principle with ±(0.2%·L+1)m accuracy and 1–50,000m test range — covering everything from short service cables to long distribution feeders.
• Additional Functions: Cable sheath fault pre-location and DC withstand voltage testing — extending the instrument's utility beyond burn-through applications for comprehensive field diagnostics.
• Generator Compatible: Operates from a standard 2kW portable generator, ensuring full functionality at remote or grid-isolated fault sites.

• Utility Emergency Response: Rapid deployment to urban and suburban cable faults — restoring power to residential and commercial customers within hours rather than days.
• Distribution Network Maintenance: Routine diagnostic testing on 10kV–35kV distribution feeder cables to identify degrading insulation before faults develop into outages.
• Third-Party Field Testing Services: Independent contractors offering on-demand cable fault location services to multiple utilities, municipalities, and industrial clients — where equipment portability and quick setup translate directly to more billable jobs per day.
• Construction & Excavation Support: Pre-excavation cable integrity verification and post-damage fault location at construction and roadwork sites.
• Substation Cable Diagnostics: Testing of buried cable connections between switchgear, transformers, and outgoing feeders within substation compounds.

The XHSC-60Q operates through a two-phase workflow. In burn-through mode, the unit applies a controlled 60kV DC voltage to the faulted cable, progressively carbonizing the high-resistance fault point until its impedance drops to a few ohms. The operator then switches to intelligent bridge mode, where the 600mA bridge current measures the exact distance to the fault with laboratory-grade precision. This single-instrument approach eliminates the logistical complexity of deploying separate burn-through and bridge devices — making it the practical choice for field crews who need to get results fast and move on to the next job.
