The PVC electrical conduit produced by Hangzhou Xinlu Industrial Co., Ltd. is a kind of hard, straight and solid wall pipe that is mainly made of rigid PVC with necessary additives and is formed through extrusion molding.

The product is used as protective tube for underground laying of urban power grid and cable and is used as protective tube for embedded power cable at crossing of traffic arteries. With supportive use of dedicated tube pillow and middle joint, it may constitute multiple-tube multiple-column cable conduit system. Socket and spigot connection is simple and reliable and is convenient for installation and construction. It can properly solve the prominent problems of long time exposure due to excavation of road during the construction that may bring impact on urban traffic and can ensure completion of excavation, laying and backfilling during nighttime and re-open to traffic in the day time. Now it is a high quality inexpensive cable protective conduit widely used in urban power grid transformation and construction project .

Light in weight, can be carried by one person and is convenient for transportation.

The inner wall is smooth with small friction coefficient and the cable can pass through smoothly without damage.

Good heat-resistance quality with sufficient strength and will not be distorted under environment with temperature of 80℃ and over .

Excellent insulating property

High compression resistance and shock strength, the rigidity of the anti-compression ring reaches 10Kpa and can bear 1kg heavy punch and 2m height impact force.

Rust and chemical resistance with good flame retardancy and is immediately extinguished upon leaving the fire.

Good water resistance and can be long used in humid environment or in water. Bacterium is not easily bred. As PVC is not subject to the influence of residual chlorine, there will be no risk of crack or leakage. The inner wall of the pipeline is smooth and bacterium will not be easily bred. Moreover, it is resistance to general sterilization chemical products. PVC pipeline system can resist invasion of all forms of bacterial

Convenient and easy for construction and installation with low cost. The pipe adopts socket and spigot connection type and is convenient for connection. There is a rubber seal ring at the joint to adapt to expansion caused by heat and contraction caused by cold.

Low comprehensive investment with fast return and bring immense social and economic benefits.

Long service life without necessary for maintenance in thirty years.
