Product Introduction
MPP power cable protection pipe is made from modified polypropylene, offering high temperature resistance and external pressure resistance. Divided into excavation type and trenchless type. MPP trenchless pipe (jacking/pulling pipe) is suitable for high voltage transmission lines and cable ducts above 10KV.
Features
Excellent electrical insulation
High heat deflection temperature and low temperature impact performance
Higher tensile and compressive properties than HDPE
Light, smooth, low friction – hot melt butt welding
Long-term service temperature: 5°C to 70°C
Applications
Municipal, telecom, electric power, gas, water, heating pipeline projects.
