Nanjing Airfly Electronics Technology Co., Ltd. (Airfly Tethered) was established in June 2018. It is a globally leading full-link, all-scenario solution provider of tethered systems, always focusing on the applications and solutions of tethered scenarios.

We focus on the R&D, production, and sales of tethered drones and related products. Through the innovative “Tethered Supermarket” platform, we provide modular solutions for global customers. Customers can precisely select online:

· Ground power stations (AF-G series),

· Aerial power modules (A unregulated and WF regulated series),

· Tether winches (AF-T series), and

· Scenario-based system kits (SF series),
to build customized tethered systems independently.

Backed by top university technical teams such as Nanjing University and Southeast University, we hold core patents for high-power tethering systems (5–60kW), fully compatible with DJI M30 / M350 / M400 / FC30 / FC100 and other industrial drone platforms.

We achieve over 24 hours of continuous endurance, centimeter-level hovering accuracy, and stable deployment in extreme environments.

Our solutions have been successfully applied in key scenarios such as:

· All-weather monitoring in Middle Eastern oil fields,

· Disaster emergency communication in Southeast Asia,

· Border security patrols in Europe,

serving over 80 international customers across more than 30 countries and regions.

As an important participant in the low-altitude economy, we continuously integrate R&D, business matching, and global service resources, aiming to simplify the deployment process of tethered systems.

Visit the Airfly Tethered Supermarket now to experience the one-stop solution of "Selection - Configuration - Delivery", empowering intelligent upgrades in fields such as power inspection, emergency communication, and security monitoring.
