AI Technical Summary

Technical Problem

Existing cables are prone to accumulating moisture in humid environments, which leads to a decrease in insulation performance. They are also prone to melting and burning at high temperatures, failing to meet the comprehensive requirements of waterproofing, fire resistance, and tensile strength. They are easily damaged by external forces and cannot stably transmit power and signals in complex scenarios.

Method used

It adopts a multi-layer structure design, including conductors, signal lines, supporting rubber layers, fireproof layers, and protective layers, combined with water-absorbing layers, water channels, and shape memory metal mesh. The heating wire and vacuum drain valve are controlled by humidity and temperature sensors to achieve high drainage, fire resistance, and tensile strength, and it has an adaptive adjustment function.

Benefits of technology

It achieves stable electrical and signal transmission in humid and high-temperature environments, has high fire resistance, can quickly expel internal moisture, extend cable life, reduce fire risk, and improve system reliability.
