MPP PIPE

MPP high voltage power cable sheath

Product introduction

At present, my country's high-voltage wires and cables have gradually moved from overhead to fully buried underneath. Buried power cable pipes have gradually been replaced by new MPP power cable protective sleeves from the original relatively ordinary cement pipes. MPP power cable protection sleeve is resistant to temperature and high voltage, high impact resistance, and high flexibility. It is a power cable protection sleeve with excellent performance.

MPP power cable protection sleeves can be used for direct burying, and can also be used for jacking pipes (traction pipes) as protection sleeves for power cables. When used for pipe jacking, it can be connected in the form of hot-melt butt joints longer than hundreds of meters, and it can be pulled into the pre-drilled holes at one time. Single root or multiple roots (integrated-east)-complete the traction work in one time.

This product is especially suitable for occasions where excavation is not allowed such as crossing roads, buildings, and rivers. Save labor, labor, time, and expense greatly improve work efficiency.

Main product performance

Insulation performance: MPP high voltage power cable protection sleeve can withstand 35KV high voltage.

Heat resistance performance: The Vicat heat resistance temperature of the MPP high voltage power cable protective sleeve is greater than or equal to 120°C.

Compressive performance: The ring stiffness of the MPP high-voltage power cable protective sleeve is greater than or equal to 120°C.

Impact resistance: MPP high voltage power cable protection sleeve can withstand the impact force of a 1.0KG heavy hammer (hammer radius 20mm) falling freely from a height of 2 meters after being stored at -5°C for 8 hours.

Tensile strength: MPP high-voltage power cable protective sleeve can withstand a tensile force of 22 MPA per square centimeter at room temperature, and the tensile strength of its thermally welded butt part exceeds the strength of the tube itself.

Safety performance: MPP high-voltage power cable protection sleeve can realize one-time excavation and one-time installation of hundreds of meters. Especially after the construction of urban roads, when excavation is not allowed for several years, today, the method of traction is adopted without excavation, and the pipe jacking technology can be installed 100 meters at a time, and it can be installed at a time with a single or multiple roots. It has its advantages in the installation projects of obstacle lines such as crossing rivers and railways.

Sealing performance: MPP high-voltage power cable protection sleeves are connected by hot-melt butt connection, and the connected pipelines form a whole, no leakage, effectively guaranteeing the insulation of the power cable, thereby protecting the safety of the power cable operation to the greatest extent .

Service life: MPP high-voltage power cable protection sleeve is corrosion-resistant and has excellent anti-aging performance. The service life can reach more than 50 years.

MPP pipe construction instructions

1. For pipe transportation, it is strictly forbidden to throw, hit, score, or expose to the sun during the construction process.

2. The axis of the two pipes should be aligned during the hot melt butt joint, and the end face should be cut vertically and flat.

3. The processing temperature, time and pressure are adjusted accordingly according to the effect of weather conditions.

4. The minimum bending radius of the pipe should be > 75 outside diameter of the pipe surface.
