In this comprehensive field demonstration, we showcase the complete workflow of the XZH TEST Underground Cable Fault Location System for 32kV applications. Watch as our technical team performs real-world fault diagnosis on medium voltage underground cables - from initial TDR pre-location using the 400MHz multi-pulse system, through precise route tracing with electromagnetic detection, to centimeter-accurate pinpointing using acoustic-magnetic synchronization. See how the integrated 5-component system delivers 0.1m accuracy across cable lengths exceeding 120km, providing utility crews and electrical contractors with professional-grade fault location capabilities.
