Column tube occluder
1) Technical concept
With the economic development and the needs of urban construction, more and more power cables and communication cables are laid underground . These cables need to be equipped with cable protection pipes at the crossing, entrance, exit and wall positions. The survey research, market capped with protective tube provided the presence of rainwater debris into the pipe, the cable long soak in water are corrosion problems, although some protection tube will be perforated at the bottom to achieve a drainage effect, but some use After time, it will be blocked by domestic waste, books, branches and leaves, etc., failing to achieve the expected results. Also part of cement, and other fire clay pipe outlet plugging material, but because of thermal expansion, and the pipe material between the sun and wind and other factors cause plugging material feed cracking off Effect plugging effect. If there is no accumulation of water and debris in the protection pipe for a long time, it will undoubtedly make the cable run more safely and effectively.
