Product Description

Product Description

18kw Drone Tether Station for Long-Duration Missions with 220m Auto Winch Tether Drone Cable

      The 18kw tethered power supply system is perfectly adapted to the heavy load UAV with MTOW 60~90Kg.  The tethered drone system includes a robust ground power station, offering reliable energy transmission through a high-strength tether cable, eliminating the need for frequent battery replacements and extending the drone's operational time significantly.

      Designed for high-endurance drone operations, this advanced system delivers stable 18000W continuous power with constant voltage output, ensuring uninterrupted flight for critical missions such as surveillance, inspection, and emergency response.

Function characteristics

1). Safety protection: Strong and weak current separation design, with input undervoltage, input overvoltage. Output overvoltage, output overcurrent, output short circuit, and output overheating protection functions. The input and output withstand voltage is ≥ 3000VDC, and the cable insulation layer withstand voltage is ≥ 3500VDC. 

2). Data communication: Wired and wireless communication functions, remote display and control, data viewing and downloading; fiber optic communication optional.

3). Automated winch reel: Synchronously retracting and releasing cables following the takeoff and landing of the drone, automatic adjusting the tension, and backup battery to activate cable reel in function in case of power cut off.

4). Data display: The touch screen displays data and status of output voltage, output current, output power, cable reel out length, operating time, equipment temperature, total power consumption, and fault records.

5). Setting and adjustment: Support the setting and adjustment of parameters such as tension and speed for reel in&out cable, date and time, output voltage, safety meters, alarm temperature, etc. and support Chinese and English.

6). Power supply 25000W/100L diesel generators is recommended.
