Advantages of PE Power Cable Protection Pipe

1. Excellent physical properties are produced with high-quality polyethylene raw materials. It has good rigidity, strength and flexibility. It is conducive to pipeline installation

2. PE power pipe is corrosion resistant and has 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 corrosion resistant, and the service life is generally only 30 years. PE resistant pipes can be resistant to a variety of chemical media and are not affected by soil corrosion.

3. PE power pipe with good toughness and deflection is a kind of high toughness pipe, with breaking elongation of more than 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 threading is easy, and the construction period is efficient.

5. Good electrical insulation performance, long service life (more than 50 years for buried pipes), durable, safe and reliable line operation.

6. PE casing is light in weight, easy to repair, install and maintain, and easy to transport and operate.

7. Small diameter pipes can be coiled, with long pipe section, few joints and easy installation.

8. The pipes can be made into various colors to show the difference.

9. PE with excellent low-temperature impact resistance has extremely low low-temperature embrittlement temperature and can be safely used in the temperature range of - 20-40. During winter construction, due to the good impact of the material, the pipe will not be brittle.

10. Compared with other metal pipes, PE pipes have good wear resistance. The abrasion resistance is four times that of metal pipe.

11. There are many new construction methods for power casing. In addition to the traditional excavation method, PE pipes can also be constructed by a variety of new trenchless technologies, such as pipe jacking, lining, pipe cracking, etc.

PE Power Cable Protection Pipe Application Field

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, intelligent transportation and other cables.
