I. Product Introduction of Ginde Buried High Voltage Power Cable CPVC Conduit
Properties of Ginde Buried High Voltage Power Cable CPVC Condui
1. Light weight: generally the weight is 1/10 of the same kind of pressure pipe, 1/6 of the steel pipe. It is very convenient to transport and install.
2. Easy for construction, the economic benefit is great: the power cable protection pipe is mainly composed by the junction, the waterproof seal loop, bracket parts and so on. The design is reasonable and easy for construction, there is no need to pour concrete protection layer, the bracket uses the combined type connection which shortens the construction cycle, no radioactivity carcinogen, and the economic benefit and social efficiency are great.
3. The feather of corrosion resistant is well: PVC-C is able to bear the corrosion of the acid, alkali, salt and so on chemical solvents, and it will not craze to contact grease.
4. High intensity, flame retardant, smoke suppression, heat-resistant, long life time: the power cable protection pipe has fully overcome the disadvantages of bad anti-weathering steel in common PVC pipe, the most difference is that the vicat temperature of the PVC-C power cable conduit is 93, which is about 20 higher than the PVC. Compared with the traditional form of the asbestos and concrete, the characteristics are the good suppleness, high temperature resistant, not easy to break and age, long life time, no radioactivity pollution and so on. Its intensity can replace the steel pipe, and also it has overcome that the steel pipe is susceptibility to corrosion and the closed magnetic circuit will cause the temperature of the single core cable too high to be damaged; the anti-flaming class of the PVC-C tubing is FV-0, the main body of which can be burnt, it will be off immediately without fire; no heat transfer basically, the linear expansion coefficient is 6.3X10-5cm/cm , the vicat temperature is higher than 93.
5. Superior price performance ratio: the PVC-C stubbing is lower than the same kind of concrete pressure pipe, and 20%lower than the same kind of steel pipe, the synthesis cost can decrease at 15%.

II. Application Range of Ginde Buried High Voltage Power Cable CPVC Conduit
This pipe is mainly used for protecting the electricity tube and the cable inside the pipe in electrical and telecommunication project.
III. Production Technique of Ginde Buried High Voltage Power Cable CPVC Conduit
1.Production Equipment
Ginde imports the plastic extruder (extruded stubbing) from Germany Krauss Maffei Company which adopts the most advantage technology for design and production. The advanced performances are fast extruding molding, automatically cut with fixed size, hot-melt expansion on line and microcomputer software controlling all producing process.
In the microcomputer (C5) controlling the production process, the starting time, temperature controlling standard can be preliminarily input and set according to the process specifications of the produce working. At the same time, the modification of the running speed, melt pressure, extruding outcome, twisting force load and regulations data and so on will automatically be monitored and recorded, storage for reading, dangerous condition warning, automatically closing down and display the modification advice or correcting description. (Can be read for three languages), so it can guarantee the no damage of the equipment and the normal running of the production process at all.
The advanced mechanical structure design has superior performances of second air out, repeating compression, melting moderation and fast extruding process. At the same time the large scale inward mixing equipments of automatically computation transportation, closed with no dust, mixing dispersed equably can guarantee the continuous process of production autoimmunization.
