JOUAV Drones Survey 800 km of Power Lines After Typhoon Maysak
CHENGDU, China, July 4, 2026 — Typhoon Maysak (the year's 10th typhoon) brought violent winds and torrential rainfall to Guangxi, China. Qinzhou, Fangchenggang, and other areas experienced prolonged extreme rainfall, with localized 24-hour precipitation exceeding historical records. Widespread flooding, road collapses, and fallen trees damaged power infrastructure, causing outages on multiple transmission and distribution lines. The risk of secondary disasters further heightened the urgency of flood control and power supply restoration.
In response, JOUAV joined the Electric Power Research Institute of Guangxi Power Grid and its Production Command Center to form a drone emergency response team. The team traveled to Qinzhou to work alongside the Qinzhou New District Power Supply Bureau of Guangxi Power Grid, conducting emergency inspections of power lines in affected areas. Using the CW-15 fixed-wing VTOL UAV, the team surveyed damaged areas to help maintain reliable electricity supplies to residential communities and critical flood control facilities.
Rapid Inspections Amid Challenging Weather Conditions
The inspection mission faced multiple challenges, including persistent heavy rain, strong wind gusts, flooded roads and slippery mountain slopes. These conditions significantly narrowed the available flight windows.
After assessing the weather and operating conditions, the emergency response team took advantage of brief breaks in the rainfall to conduct visual inspections with the CW-15. The team focused on identifying damage to 10 kV power lines, including damaged or fallen poles, broken conductors, and other potential hazards.
The aerial surveys provided a broader view of damage across the affected power network, supplying timely information to support debris clearance, repair planning, and power restoration. By helping crews identify hazards and assess damage more efficiently, the drone-assisted inspections improved the overall response to post-disaster power infrastructure risks.
Technology Supporting Emergency Response
As China enters the peak flood season, flooding and geological hazards continue to threaten infrastructure and public safety in multiple regions. JOUAV remains prepared to deploy its drone technology in emergency response operations, supporting frontline teams in assessing infrastructure damage and helping restore essential services.
Through its continued involvement in disaster response, JOUAV aims to apply UAV technology to critical infrastructure protection and demonstrate its commitment to public safety and reliable power supply.
