AI Technical Summary

Technical Problem

During the laying process, the protective layer of the cable may wear down due to friction with the inner wall of the pipe and contact with sharp objects from the outside, posing a safety hazard of breakage and damage to the internal structure.

Method used

It adopts a multi-layer structure design, including an insulation layer, a support layer, a shielding layer, a fireproof layer, an inner wear-resistant layer, an armor layer, a buffer layer, and an outer wear-resistant layer. Through the combination of these layers, it provides multiple protections against wear and cuts.

Benefits of technology

It effectively prevents cable wear and cutting caused by external factors during the laying process, ensures the integrity and safety of the internal structure, and improves the cable's abrasion resistance and protection capabilities.
