HDE Underground Cable Tester 8kVDC

April 29, 2026

The UCT-8 Underground Cable Tester demo shows how the self-contained tool applies 8 kV DC to de-energized underground power cables to measure leakage current and quickly identify faults. The video highlights real-world outage scenarios, built-in safety features, and how the UCT-8 simplifies and speeds up underground cable troubleshooting for line crews.
