OPGW & Ground-Wire Emergency Repair Robot

This live-line emergency repair robot is designed for fast response on OPGW (Optical Ground Wire) and overhead ground wires, especially when access is difficult and time is tight. It flies to the target span, lands on the wire, and then travels along the line to the defect location. It installs temporary reinforcement fittings at the defect location. This stabilizes damaged strands and helps prevent further deterioration—while the line stays in service. The focus is fast stabilization and risk control. It buys time until a planned permanent repair can be completed. Built for real line conditions: long spans, difficult terrain, and limited ground access—where reducing crew exposure matters.
