问题解答：
CPVC power cable protection conduits used mainly for the installation of power cables and starting guide and protect cables role. Alternative power systems currently used by the asbestos cement pipe and tube, and so on. The product is corrosion resistant, heat-resistance, anti-aging, compressive strength, it is not Whirlpool, flame retardance, and Strong high-voltage insulation performance, wear resistance, and wall friction coefficient, pollution-free, light weight, long life and other characteristics. Construction is convenient and without pouring concrete protective layer, reducing the project cost advantages. → product characteristics : 1, excellent heat resistance : can adapt to the use of power lines due process overload and short circuit of the high temperature; 2, excellent electrical properties : material for the performance of their higher intensity and volume resistivity of insulation, security is good; 3. excellent corrosion resistance and anti-aging properties : apply to the soil and working environment, long life; 4. excellent flame retardance : difficult combustion; 5, smooth wall formation, the friction coefficient, good wear resistance : in the installation process can greatly reduce the damage to power lines, improve work efficiency; with the traditional asbestos cement pipes, the The product is light weight, good flexibility, earthquake-resistant and differential settlement, and not at the construction site encapsulation pouring concrete; Transport construction is simple, low cost, can greatly shorten the construction period. Double-wall corrugated HDPE pipe is high-density polyethylene extrusion by the same time the outer wall of corrugated wall and a layer of a smooth solution Guitar Squeeze Molding. In addition to its ordinary plastic pipe all the good corrosion resistance, insulation, wall smooth flow resistance characteristics of a small, a result of the introduction of a special ring hollow structure, so it has excellent ring stiffness and strength and good toughness, light weight, impact resistance strong and difficult to breakage characteristics. Currently in developed countries in various fields have been widely used, especially in the United States, Canada, Japan and many European countries. double-wall corrugated pipe drainage widely used in municipal sewage, agricultural irrigation, mine ventilation, chemicals, telecommunications cable sheathing, and other fields. Practice has proved that to meet the same strength and stiffness requirements, using double-wall corrugated pipe than ordinary plastic pipe material savings 30% ~ 50%, transport and easy installation, Construction reduced the labor intensity, but also decreased the amount of total investment, are concrete pipe. Cast Iron Pipe ideals behind. [Characteristics] 1. High strength, resistance, impact resistance is good; 2. Anti-settlement good performance and can be applied to the soft sand foundation; 3. Link convenient connector no leakage; 4. Smooth wall, a small friction, through hydro power; 5. corrosion resistance and pollution-free. 6. Light weight, easy handling and easy construction, engineering lower total cost. [Application] 1. Municipal projects, residential quarters of buried water and sewage disposal; 2. Farmland irrigation, water drainage; 3. Sewage treatment plants, waste disposal field drainage transportation; 4. Highway Pipeline; 5. Chemical ventilation pipes and chemicals, Mine for the transmission fluid; 6. electricity, telecommunications cables, and so on to protect the casing. 7. Well pipeline inspection of the overall processing
