Digital Burn Through Bridge for Cable Fault Location in High Voltage Large Section Cables|XHSC-60Q

The XHSC-60Q Digital Burn Through Bridge is a high-performance cable fault pre-location instrument engineered for 60kV and below high-voltage power cables. Designed specifically for renewable energy installations, critical infrastructure, and industrial power distribution networks, it delivers up to 600mA of controlled burn-through current to convert high-resistance faults into low-resistance, locatable faults — enabling rapid and precise fault pre-location on large-section, long-distance underground cables.

Unlike conventional burn-through bridges targeting generic utility applications, the XHSC-60Q is purpose-built for operators managing large-scale solar farms, wind power collection systems, data center power feeds, and heavy industrial cable networks — where cable cross-sections frequently exceed 400mm² and fault resistance can reach tens of kilo-ohms.

• High Current Output: 600mA maximum burn-through current, effectively converts high-resistance faults (up to tens of kΩ) into traceable low-resistance states on large-section cables.
• Wide Voltage Range: 0–60kV continuously adjustable output, covering the full spectrum of medium and high voltage cable fault diagnosis requirements.
• Intelligent Digital Control: Microprocessor-based regulation with real-time voltage/current monitoring and automatic safety interlocks for operator protection.
• Compact Portable Design: Weighing approximately 25kg with dimensions 30cm × 46cm × 50cm, easily transportable in field service vehicles for on-site deployment.
• Generator Compatible: Powered by standard 2kW+ portable generator, enabling operation in remote renewable energy sites without grid access.
• CE Certified: Meets European safety and EMC standards for professional electrical testing equipment.

• Solar PV Farms: Fault location on buried 35kV collector cables linking inverter stations to substations.
• Wind Power Plants: Diagnostics on medium-voltage inter-array and export cables in onshore and offshore wind installations.
• Data Centers: Critical power feed cable integrity testing to prevent unplanned downtime on redundant supply paths.
• Industrial Parks & Mining: Large-section buried cable fault location in heavy industrial and extraction environments.
• Utility Substations: Pre-location of high-resistance faults on 10kV–35kV distribution feeder cables.

The XHSC-60Q operates on the burn-through principle: a controlled high-voltage DC output is applied to the faulty cable, gradually heating and carbonizing the fault point. This process reduces the fault resistance from potentially hundreds of kilo-ohms down to a few ohms or less. Once the fault is converted to a low-resistance state, standard TDR (Time Domain Reflectometry) or impulse current methods can be used to precisely measure the distance to the fault — dramatically improving pre-location accuracy and reducing excavation time.
