AI Technical Summary

Technical Problem

The outer protective layer of existing cables is easily damaged by pulling, resulting in reduced overall protection and insufficient safety.

Method used

The structure features a torsion-resistant braided layer made of tin-plated copper wire, combined with a PUR sheath and an aluminum foil shielded conduit, and filled with high tensile, torsion-resistant, and waterproof filler in the filling groove to form a multi-layer protective structure.

Benefits of technology

It improves the cable's tensile strength, enhances protection, ensures normal use in areas with high mechanical stress and small bending radius, and provides dual protection and good shielding performance.
