Intelligent Burn Through Bridge | Traction Power Cable Fault Pre-Location for Rail Networks | XHSC-60QXHSC-60Q Railway and metro traction power cables run long, large-section routes through tunnels, bridges and cross-bonded sections, often terminated at GIS switchgear. The XHSC-60Q was designed for exactly these systems: its 60kV burn-through with up to 400mA arc current converts high-resistance and flashover insulation faults into measurable low-resistance faults, and the
