Caption 10Addressing the industry problems such as poor reliability of cables and lack of intelligent early warning in special environments, the project developed cables and intelligent early warning monitoring systems for special environments, with the main innovations as follows:

Constructed an integrated technical system of intelligent early warning and adaptive thermal management featuring "perception-decision-control", realizing the transformation of cables from passive power transmission to active safety protection.

Developed a distributed optical fiber temperature measurement system, which has the characteristics of high temperature/space resolution and long single-channel monitoring distance, enabling advanced early warning of cables and linkage with the Internet of Things (IoT).

Caption 11Proposed a collaborative protection and integrated design method for cable functions targeting scenarios such as fire prevention, weather resistance and electromagnetic interference resistance, achieving the goals of low flame spread, low total heat release and excellent weather resistance of fire-resistant cables, and meeting the application requirements of multiple scenarios in special environments.

Developed materials such as biodegradable bio-based heat-shrinkable films. Through cable structural design and material combination, the heat dissipation efficiency of cables under abnormal working conditions has been significantly improved. The related products have good green and low-carbon characteristics, realizing the application of green and low-carbon manufacturing technology in the cable industry.
