The large-scale power pipe network renovation project requires laying 7,000 meters of cable protection pipes for the protection of underground high-voltage cables. The project needs to cross roads, green belts and around buildings with complex terrain, and has extremely high requirements for impact resistance, corrosion resistance and insulation performance of pipes. The original PVC cable protection pipes are brittle and poor in impact resistance, frequently damaged during laying, not resistant to soil corrosion, short in service life and high in annual maintenance and replacement costs. Customers need a cable protection solution that meets international power standards, can be directly imported in bulk and is convenient for construction.
Combined with the laying requirements of power projects and international standards, we customized HDPE cable protection pipes with specifications DN100-DN200mm and pressure class PN10-PN16, with a total length of 7,000 meters, matched with HDPE socket fittings, sealing rubber rings and special fixing brackets. The products are made of PE100 special insulation raw materials, with a density of 0.942-0.960g/cm³, impact strength ≥12kJ/m², insulation resistance ≥10¹²Ω・m, temperature resistance range -30℃ to 70℃, resistant to soil corrosion, acid and alkali. They comply with international power industry standards and have passed CE and ISO14001 certifications, can be directly exported, and adapt to complex underground laying environments without additional anti-corrosion treatment.
“Power cable protection has extremely high requirements for pipeline safety and insulation. The previous PVC pipes are very brittle and will be damaged by slight collision during laying, and will be corroded by soil in a few years, requiring a lot of cost for replacement every year, which is very troublesome. After choosing Henan Lukuang HDPE cable protection pipes, these pain points have been completely solved. The pipes have excellent toughness and impact resistance, will not be damaged even under external extrusion when crossing roads and green belts, excellent insulation performance, can effectively protect high-voltage cables and avoid short-circuit hidden dangers. Moreover, construction is very convenient, socket connection without complex processes. 7,000 meters of pipes were laid in 28 days, corrosion-resistant and durable, service life of more than 50 years, fully meeting international power standards, import process is smooth. We will give priority to Henan Lukuang for subsequent power pipe network renovation projects!” ——Person in charge of power engineering contractor
