WT‑6KW Tether Power System for 15‑30kg Payload Drones, Unlimited Flight Time Heavy‑Lift Drone Tether Power Supply
1. Product Overview
WT‑6KW tether power system is a high‑power ground‑station tethered drone power supply specially
built for 15‑30kg payload heavy‑lift industrial drones. Compared with regular drone battery solutions,
this tether power system realizes unlimited flight time by supplying continuous electricity through high‑strength tether cable, removing the constraints caused by frequent battery replacement. Designed for UAVs with 15‑30 kg take‑off weight, the unit accepts standard 190‑240VAC industrial mains input and outputs adjustable 600‑850VDC, with selectable output power of 6000W or 7000W. Customers can pick either 110 m or 220 m tether cable for different working‑height requirements. This heavy‑lift tethered drone power supply fits complex field projects and supports B2B bulk wholesale as well as OEM custom services from Wintooltech.
2. Key Features & Highlights
Unlimited flight‑time operation: tether power system for 15‑30kg payload drones removes battery
runtime restrictions for heavy‑lift UAV
Dual power grades: 6000W output power for heavy‑payload drone power consumption
Two tether cable options:110m and 220m cable for high‑altitude long‑hover deployment
Universal industrial AC input: 190‑240VAC input, adapt to most site power supplies
Reliable high‑voltage DC output: 600‑850VDC optimized for large payload industrial drones
Wide compatibility: fully match drones with 15‑30 kg take‑off weight
Rugged industrial ground‑station design, easy transport and fast field setup
Accept wholesale distribution orders and OEM custom modification for integrators
