Wire and cable hdpe

HDPE power protective casing is a high-tech product, which is made of high-quality high-density polyethylene resin as the main raw material, added with appropriate additives, and processed by extrusion. The product has the characteristics of corrosion resistance, aging resistance, impact resistance, high mechanical strength, long service life, excellent electrical insulation, etc. It can be widely used in the fields of buried high-voltage cables, street lamp cable protective casing, etc.

Application field of hdpe power cable

It is widely used in urban road construction, community development, garden landscape, enterprise construction and other places, as the threading sleeve of electric power, street light, lawn light, yard light, community intelligence, cable TV, communication, smart Xiatong and other cables.

Advantages of hdpe power cable

1. Excellent physical properties are produced from high-quality polyethylene raw materials. It has good rigidity, strength and flexibility, which is conducive to the installation of pipeline.    2. Corrosion resistance and long service life: in coastal areas, the groundwater level is high and the land humidity is high. The use of metal or other pipes must be protected against corrosion, and the service life is generally only 30 years. The HDPE pipes can be resistant to a variety of chemical media and are not affected by soil corrosion.    3. It is a high toughness pipe with good toughness and deflection, and its elongation at break exceeds 500%. It has strong adaptability to uneven ground settlement and dislocation of the foundation. Good seismic resistance. Small diameter pipes can be bent at will.    4. The pipe wall is smooth, the friction coefficient is small, the cable is easy to be threaded, the construction period is efficient, the weight is light, the maintenance, installation and construction are convenient, and the transportation and operation are easy.    5. Good electrical insulation performance, long service life (more than 50 years of buried pipe life), durable, safe and reliable line operation.    6. Small diameter pipes can be coiled, with long pipe sections, few joints, and easy installation. The pipes can be made into various colors to distinguish.    7. Compared with other metal pipes, HDPE pipes have good wear resistance. The abrasion resistance is four times that of metal pipe.    8. Various new construction methods. In addition to the unified excavation method, HDPE pipes can also be constructed by a variety of new trenchless technologies, such as pipe jacking, lining, pipe cracking, etc. This is the only choice for some places where excavation is not allowed.    9. The low temperature embrittlement temperature of HDPE with excellent low temperature impact resistance is extremely low, and it can be safely used within the temperature range of 20 to 40. During winter construction, due to the good impact of the material, the pipe will not be brittle.
