MPP power conduit
The MPP-modified polypropylene power cable conduit is a solid-wall pipe with smooth inner and outer surfaces, produced by extrusion of modified polypropylene (PP). This pipe boasts excellent electrical insulation properties, is lightweight and environmentally friendly, resists aging, withstands high temperatures, resists external pressure, exhibits high axial strength, and possesses outstanding ductility and flexibility. It enables the installation of power cables in special areas such as roads, railways, and riverbeds without requiring extensive excavation or disruption of the ground surface. This pipe can meet the requirements for protective conduits used with high-voltage power cables rated above 10 kV.
