The XHSC-60Q is a high-current digital burn-through bridge engineered specifically for rapid high-resistance-to-low-resistance fault conversion on large-section, long-distance high-voltage power cables. With a burn-mode output of 60kV and a short-circuit current of 600mA — the highest in its class — it reliably breaks down carbonized discharge channels in oil-paper and XLPE insulated cables where lower-current instruments struggle to achieve stable conduction.
Performance Highlight: 600mA short-circuit current in burn-through mode — three to six times higher than conventional 100–200mA burn-through instruments. This means faster fault conditioning, fewer burn-through cycles, and more accurate subsequent bridge positioning on large-section cables with high-resistance faults.
High-resistance cable faults — particularly in long, large-conductor cables — present a high-impedance discharge path. A burn-through instrument with only 100–200mA of short-circuit current often requires repeated cycles to carbonize and stabilize the fault channel, and in some cases fails to achieve sufficiently low resistance for accurate bridge measurement. The XHSC-60Q’s 600mA output delivers proportionally higher energy into the fault point, accelerating the transition from unstable high-resistance arc to a stable low-resistance conduction path.
Once the fault is conditioned, the integrated intelligent bridge module takes over. Operating at 0–4kV with the same 600mA current capability, it drives sufficient test current through the now-low-resistance fault to ensure clean, repeatable ratio measurements — critical for achieving the specified ±(0.2%·L+1)m positioning accuracy.

The XHSC-60Q incorporates dual overload and short-circuit protection with autoranging impedance matching. A high-voltage enable mushroom button provides emergency power-off. The high-voltage adjustment knob is interlocked with the HV switch — boost voltage is only possible when the knob is returned to zero and the mode indicator confirms bridge or burn-through selection. All operations are conducted via an insulated rotary encoder at ground potential, with the LCD display and bridge electronics floating at high potential for measurement accuracy while the operator remains entirely isolated.
