PDK41302-2×22AWG+1SMF Tethered Drone Cable, 500 N, OD 3.4 mm

Product introduction

This high-performance airborne tether is designed for tethered unmanned aircraft systems (UAS) that need continuous power and a real-time data link. It removes the flight-time limit imposed by on-board batteries, allowing the aircraft to stay airborne for hours or even days. The cable integrates low-resistance power conductors with an optional fibre or shielded signal pair, all enclosed in a lightweight, highly flexible sheath that withstands harsh outdoor conditions.

Unlike standard cables, this tether is designed to withstand the demanding dynamics of drone operation: repeated winding and unwinding, small-radius bending and high tensile loads during ascent or in strong wind. Aramid (Kevlar) yarn reinforcement provides high tensile force without excessive weight, while the UV-stabilised PUR sheath resists abrasion, oil and extreme temperatures. The result is a reliable umbilical that delivers stable power from a ground generator or battery pack to the aircraft, enabling unlimited endurance without landing to change batteries while maintaining high-speed communication of video, telemetry or command signals.

Well suited to:

Tethered multirotor and fixed-wing drones for border patrol, traffic monitoring and event security

Emergency communication relay drones (disaster recovery, wildfire management, search and rescue)

Military reconnaissance, jamming and signals intelligence platforms

Continuous inspection of power lines, pipelines, wind turbines and solar farms

Temporary mobile communication masts (drone as an airborne signal tower)

Agricultural survey and long-term environmental monitoring

Any application requiring unlimited flight endurance, reliable power and a real-time data link without the weight penalty of heavy batteries

The PDK-AT series meets the UAS requirements for high power transmission (15–20 A continuous) and low-latency data communication under harsh environmental conditions, including strong UV, sandstorms, rain and extreme temperatures. The cable is not designed for underwater sealing but for dynamic airborne deployment, where mechanical toughness, low weight and bending flexibility are essential.

The cable is a suitable choice for industrial drone operators, defence contractors, public safety agencies and research institutions seeking ready-made or customisable tether solutions that maximise flight time and system reliability.
