[0002] Cable protection pipes mainly include types such as PVC, PE, HDPE, steel-plastic composite, silicone, PA, etc. PVC cable protection pipes are a commonly used cable protection pipe material, made of polyvinyl chloride, suitable for cable protection for indoor or underground laying, with excellent corrosion resistance, wear resistance and weather resistance. Its manufacturing process is simple and the cost is low, suitable for general low-voltage cable protection.

[0003] Existing PVC cable protection pipes have certain drawbacks when in use. When traditional PVC cable protection pipes are spliced, the sealing effect of the splicing structure is poor, and the cables are piled up together, making it difficult to dissipate heat; in addition, the corrosion resistance of the pipeline itself is poor in high-temperature, high-humidity, high-acid-base areas or application environments, especially when the PVC cable protection pipe is exposed in high-acid-base areas on the ground; therefore, in order to solve the above problems, we propose a PVC cable protection pipe that avoids cable piling up and has an anti-corrosion coating.
