HDPE electrical pipe is a pipe made of high-density polyethylene material for electrical wiring or cable protection. This pipe has excellent electrical insulation performance, good waterproof and insulation performance, as well as strong high temperature resistance and impact resistance.
HDPE material itself has non-toxic, tasteless, high crystallinity, non-polarity and other characteristics, its use temperature up to 100℃, hardness, tensile strength and creep better than low-density polyethylene, and has good wear resistance, electrical insulation, toughness and cold resistance. In addition, the HDPE material has high chemical stability, is insoluble in any organic solvent, is resistant to acid, alkali and various salts corrosion, the film has small permeability to water vapor and air, and low water absorption. However, the aging resistance of HDPE is poor, and the environmental stress cracking resistance is not as good as that of low-density polyethylene, especially under the action of thermal oxidation, the performance will decline, so in practical applications, antioxidants and ultraviolet absorbers need to be added to improve these deficiencies.
HDPE electrical pipe is usually used to protect electrical lines and prevent cables from physical damage. It also provides good electrical insulation to protect cables from interference from the external environment. HDPE electrical pipe has many advantages, making it an ideal choice for cable protection:
1. Corrosion resistance and chemical stability: HDPE material has good corrosion resistance and can resist the erosion of chemicals such as acids and alkalis. It is suitable for various complex environmental conditions and protects cables from damage by external chemicals.
2. Mechanical strength and wear resistance: HDPE electrical pipe has high strength and rigidity, and can withstand soil pressure, external force impact, etc., to ensure the safe operation of cables. At the same time, its wear resistance is 4 times that of metal pipes, further enhancing the protection effect.
3. Electrical insulation performance: HDPE material itself has excellent insulation performance, which can effectively prevent cables from external electromagnetic interference and ensure the stability of power transmission.
4. Adaptability and durability: HDPE electrical pipe has good adaptability and durability, can adapt to uneven ground settlement and dislocation of the foundation, has good seismic resistance, and small-diameter pipes can be bent arbitrarily to ensure the stable operation of cables in various environments.
5. Construction convenience: Compared with traditional metal pipes, HDPE electrical pipe is lighter, easier to carry and install, and can reduce construction costs and time. In addition, it can also be constructed using a variety of new non-excavation technologies, such as jacking, lining, split pipe, etc., which are suitable for places where excavation is not allowed.
6. Environmental adaptability: It has good cold resistance and flexibility, can be used safely in low temperature environments, and has good low thermal conductivity and wear resistance, providing comprehensive protection for cables.
