MPP power sheath

MPP modified polypropylene power cable sheath is a solid-walled pipe with smooth inner and outer walls, which is extruded from modified polypropylene PP. The pipe has excellent electrical insulation, light weight and environmental protection, not easy to age, high temperature resistance, resistance to external pressure, high axial strength and excellent ductility and flexibility. It can destroy the surface without a lot of digging and dredging. , riverbed and other special areas for laying power cables. The pipe material can meet the needs of the sheath pipe material for high-voltage power transmission cables above 10KV.
