XHSC-60Q Digital Burn Through Bridge | Fast, Certain Cable Fault Pre-Location for Service Teams The XHSC-60Q integrates a 60kV burn-through unit, a high-current digital bridge and an intelligent fault diagnosis function in one trolley case. High-resistance and flashover faults are burned down to stable low-resistance faults with up to 400mA arc current, then pre-located by the 750mA digital bridge or cross-section mode with ±(0.1%·L+1)m accuracy over 1 to 50000m.
