AI Technical Summary

Technical Problem

Existing composite cables rely solely on a single layer of insulation to isolate strong and weak electrical signals, lacking electromagnetic shielding, which leads to signal interference and unclear structure.

Method used

It adopts a multi-layer structure design, including an outer protective sleeve, a first insulating sleeve, a copper wire braided shielding layer, a second insulating sleeve, and a copper foil shielding layer, combined with a TPU partition frame, a fire-resistant layer, and an aramid yarn tensile layer to enhance electromagnetic protection and structural stability.

Benefits of technology

A multi-layered electromagnetic protection system is formed to improve the ability to resist electromagnetic interference, ensure signal transmission quality and stability, enhance the applicability and fire resistance of cables in complex environments, and extend their service life.
