AI Technical Summary

Technical Problem

Existing tethered drone cables suffer from excessive weight and volume, poor adaptability of ordinary TPU sheaths, affecting the drone's flight performance and endurance, and are prone to wear and leakage in extreme environments.

Method used

The cable employs a double-layer braided shielding reinforcement layer of metal-plated ultra-high molecular weight polyethylene and Kevlar aramid fiber, combined with a silica-filled modified polyurethane elastic outer sheath, designed as an integrated tensile and shielding structure. This, along with PTFE insulation layers of different densities on the inner and outer layers and a sharkskin-textured outer sheath, enhances the cable's lightweight, flexibility, and abrasion resistance.

Benefits of technology

This achieves cable lightweighting, improves service life and safety in extreme environments, reduces maintenance costs, and enhances the tensile strength and flexibility of the cable, making it adaptable to a wider range of environmental conditions.
