This MPP power protection pipe adopts modified polypropylene material and single-layer solid wall structure, which is specially designed for power cable protection, communication fiber optic cable casing and high-voltage transmission projects to provide high-reliability protection solutions. Through the optimization of anti-cracking formula, the product has an elongation at break of more than 400% and a voltage resistance of 35kV/mm breakdown strength, which can effectively resist the risk of electric breakdown. Its flame retardancy reaches UL94-V0, and its impact strength passes the hammer impact test, adapting to the harsh outdoor environment and construction collision.MPP power protection pipe adopts non-excavation dragging technology, which can cross the roads, rivers and other obstacles, and the hot-melt docking process realizes the gapless connection, which significantly reduces the impact of the construction on the surrounding environment. The inner wall silane cross-linking layer reduces the wear and tear of cables, the outer wall carbon black layer enhances the aging resistance, the anti-cracking formula extends the service life, and the voltage resistance guarantees the safety of power transmission. MPP power protection pipe is widely used in urban power grid upgrading, new energy charging piles and rail transit projects, and continues to provide efficient protection for power infrastructure by virtue of its non-excavation towing and flame retardant advantages. Intelligent monitoring of pre-buried interfaces to realize real-time tracking of pipeline health status, helping the construction of smart grid.
