MPP Power Conduit for Underground Cable Protection - High Temperature Resistant, Non-Excavation Installation, 50-Year Durability

1、 MPP power pipe

Material: Modified Polypropylene (MPP)

Purpose: Underground laying protection pipes for power cables and communication cables, suitable for non excavation pipe jacking construction, direct burial and other scenarios.

Execution standard: GB/T 20218-2020 "Non excavation modified polypropylene plastic conduits for power cables".

2、 Core advantages

High temperature resistance

Long term use temperature -20 ℃~110 ℃, short-term temperature resistance can reach 140 ℃, far from ordinary HDPE pipes (temperature resistance ≤ 60 ℃), suitable for cable heating environments.

High strength and compressive strength

The ring stiffness can reach SN8-SN16, and the compressive strength is ≥ 30MPa, suitable for high load scenarios with a burial depth of 4-8 meters (such as urban main roads and highways).

Convenient non excavation construction

Support non excavation techniques such as pipe jacking and traction, reduce road damage, and increase construction efficiency by more than 50%.

Insulation and flame retardancy

Volume resistivity ≥ 1 × 10?? Ω· m, with a flame retardant rating of V0 (UL94 standard), ensuring the safety of power transmission.

Long corrosion resistance and lifespan

Resistant to acid and alkali, electrochemical corrosion, designed for a lifespan of over 50 years, maintenance free.

3、 Application scenarios

Urban power grid renovation: Cable grounding project, especially suitable for non excavation construction in busy traffic areas.

High speed rail/highway power supply: resistant to settlement, vibration, and suitable for complex geological conditions.

Industrial park: resistant to chemical corrosion, suitable for cable protection in chemical and metallurgical enterprises.

In the field of new energy: cable laying for photovoltaic power stations and wind power plants.

4、 Construction and connection methods

Hot melt welding

Hot melt docking of pipe ports, with a connection strength equal to or greater than the pipe body, achieving seamless sealing.

Plug and socket electric fusion connection

Using an electric fusion sleeve, it can quickly fuse after being heated by electricity, making it suitable for construction in complex terrains.

trenchless technology

Directional drilling traction or pipe jacking construction, with a large traction length of up to 150 meters (DN160 pipe diameter).
