　　Working principle of Tethered Drone

　　The Tethered Drone is connected to a ground power source through a cable, enabling long-term aerial hovering and mission execution.

　　The mooring box converts the single-phase 220V (or three-phase 380V) AC power provided by the generator (mains power) into high-voltage DC power DC400-1500V and outputs it to the mooring cable. After being stepped down by the onboard power supply, it is converted into a DC stabilized output suitable for Drone Power Supply (such as 50V for 12S), providing a long endurance power supply mode for the drone.

　　Application areas of Tethered Drone

　　The application of Tethered Drone is very extensive, including but not limited to emergency rescue (emergency lighting, emergency communication, high-rise firefighting), military (intelligence surveillance, electro-optical reconnaissance, radar electronic warfare), public safety (relay self-organizing network, environmental monitoring), and civilian (nighttime power repair, high-rise building cleaning/spraying). These application scenarios require drones to remain in a fixed position for a long time to complete specific tasks.

Every three months during extended storage, perform a complete system inspection and operational check without full activation. Maintain detailed storage records including environmental conditions, inspection results, and any maintenance actions performed during the storage period.

　　Transportation and Handling Guidelines

　　During transportation, secure all components in their designated foam-fitted cases with proper restraint to prevent movement. Clearly mark cases with appropriate handling labels indicating orientation, fragility, and environmental limitations. For vehicle transportation, secure cases to prevent shifting and protect from direct sunlight or extreme temperatures. For air shipment, comply with IATA regulations for lithium batteries and electronic equipment. During loading and unloading, use appropriate equipment and techniques to prevent impact damage.
