※ Product Introduction
Guosu PVC buried power cable conduit adopts advanced scientific research technology, combined with the unique Karst landform in Guizhou region, material formula and production process5After years of experimentation and improvement, our technology and brand are far ahead, and we are now ahead of others2015year7Yueguosu Electric Power Pipe Enterprise Standard Promoted to Guizhou Provincial Local Standard (DB)52T 1048-2015PVC conduit for buried high-voltage power cables. The PVC power cable conduit used by Guosu has the characteristics of high strength, high toughness, high temperature resistance, corrosion resistance, flame retardancy, good insulation, no pollution and easy aging, light weight, and convenient construction. Its various performance indicators have met the requirements of national standards.
※ Product Features
1. Lightweight textureCompared to traditional steel pipes and cement pipes, it is much lighter in weight, making it easier to transport and lay during construction.
2Smooth inner wallThe inner and outer walls are smooth and flat, with a low friction coefficient. The resistance during cable threading is small, making it easy to thread and maintain the cable.
3. Corrosion resistanceHas excellent corrosion resistance, resistant to acid, alkali, salt and chemical media erosion, not affected by corrosive soil, can be used in corrosive environments such as chemical plants and mines, and can effectively prevent pipes from being corroded and damaged.
4. Aging resistanceThe molecular structure is stable, not easily affected by factors such as ultraviolet radiation, oxygen, and moisture, and has a long service life. Normal use can reach up to 50 years.
5. Excellent insulation performanceCan withstand3High voltage above 10000 volts effectively prevents safety accidents such as leakage and electric shock, ensures the safe operation of power cables, and provides reliable electrical insulation protection for cables.
6. Good flame retardant performanceBoth PVC and PVC-C materials have good flame retardant properties and can extinguish immediately upon ignition, especially PVC-C material. Due to its high chlorine content, its flame retardancy and smoke density index are significantly improved, which can effectively prevent the spread of fire and reduce the risk of fire.

※ Pipe connection method
Socket type adhesive bonding methodSuitable for small and medium-sized diameters (diameter ≤)630Mm) PVC power pipe. Use specialized PVC-U pipe adhesive to evenly apply glue to the inner wall of the socket and the outer wall of the socket, with a moderate coating thickness. The socket should be inserted into the socket depth1/3To1/2The length of glue application should be slightly greater than the insertion depth. After gluing10to30Insert the socket vertically into the socket within seconds, rotate slightly to ensure even distribution of glue, and lightly tap the interface with a wooden mallet to ensure a tight and seamless connection. The curing time at room temperature is about1to2Hour,24It can only withstand pressure or be buried after hours.
Hot melt welding methodSuitable for large-diameter (≥ 630 mm) pipelines or environments that require high sealing. Use a dedicated hot melt machine to heat the end face of the pipeline and the welding plate to a specified temperature, generally around 200 to 240 ℃. Connect the heated end face to the welding plate, apply uniform pressure, and cool to form a permanent connection.
※ Application Fields
Urban power grid construction and renovation, rural power grid construction, water conservancy construction, urban pipeline network renovation, industrial parks and residential areas, and new energy fields.
