What Is a Tethered Drone System?

A tethered drone system provides continuous power and data through a high-voltage cable connected to a ground power station.
This enables long-endurance flights from hours to days, making it ideal for missions requiring stability, safety, and long operation times.

Core Components:

l Ground power station (high-voltage DC output)

l Tether cable (high-strength, lightweight, optional fiber-optic)

l Airborne power conversion module (step-down to battery voltage)

l Automatic winch with tension control

l Drone platform (multi-rotor, industrial UAV, eVTOL test platform)

How to Choose a Tethered Drone Manufacturer

When selecting a supplier, consider the following:

1. Power capability

Check whether the manufacturer supports 2–40+ kW power output for your drone’s payload and endurance requirements.

2. Cable specifications

n Length: 50 m / 70 m / 100 m / 120 m

n Diameter and weight

n DC cable vs. hybrid cable vs. fiber-optic cable

n Tensile strength and insulation rating

3. Airborne module compatibility

Confirm output voltage:

n 24 V (6s)

n 50 V (12s)

n 60–75 V (18s)

n 90–120 V (28s)

n 1500 V → 118 V (eVTOL platforms)

4. Communication interface

n CAN-bus

n RS485

n Fiber-optic

n Bluetooth or APP monitoring

5. Export capability

Manufacturers with proven global shipping, customs clearance, and after-sales support will reduce project risk significantly.
