Product Description

Product Description

18kw Latest Model Automatic Cable Reel Winch Tether Drone Power System

      The tethered power supply system is perfectly adapted to the heavy load UAV with MTOW 60~90Kg, integrating UAVs with a ground-based power station through a durable tether cable, delivering continuous electricity to enable extended flight operations. This innovative solution eliminates battery limitations, allowing drones to perform prolonged missions without interruptions - dramatically improving operational productivity.

      The tethered power supply system is used for the uninterrupted operation of UAV during long flight. It has a wide range of applications in many fields such as surveillance, monitoring, aerial lighting, relay communication, high-altitude cleaning tasks (like high-rise building facade and window cleaning tasks) and other tasks at high altitude for a long time through stable power supply.

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.
