Background technique

When wiring electrical engineering equipment, it is often necessary to pass cables through the walls of the building to achieve electrical connections across the building. In order to prevent the thermal expansion and contraction of the cement on the building wall from cracking the outer sheath of the cable, causing cable leakage, it is often necessary to embed electrical engineering lines and casings in the wall, and then pass the cables through the electrical engineering lines and casings. For wiring, electrical engineering line casing can effectively protect the cables passing through the wall.

However, the existing line casings used in electrical engineering lack protection functions. When the line casings are pre-buried under the road and used, sometimes heavy equipment on the road squeezes the line casings, causing the lines to wear casings.
