AI Technical Summary

Technical Problem

The existing cable protection pipes have insufficient tightness and poor sealing at the plug-in connections, resulting in limited cable protection.

Method used

The MPP cable protection tube, featuring a horn-shaped design, connects via an interlocking ring and a beveled opening. It also utilizes an air inflator to expand the rubber ring, enhancing both fixation and sealing.

Benefits of technology

It achieves high tightness and sealing of cable protection tubes, improves the protection stability of cables, and supports pluggable extension of use and recycling.
