Introduction to HDPE power cable conduit
The power cable protection pipe is a new type of plastic pipe manufactured with a special formula and processing technology, which has a series of advantages such as high strength, good stability resistance, easy cable threading and laying, simple construction, and cost savings. As a top pipe construction that highlights the product's personality, it meets the development requirements of modern cities and is suitable for burial depths ranging from 2-18 meters. The HDPE power cable sheath is constructed using non excavation technology, which ensures the reliability of the pipeline network, reduces the failure rate of the pipeline network, and greatly improves the urban environment.
Performance of HDPE power cable conduit
It has the characteristics of high temperature resistance and external pressure resistance, and is suitable for cable conduit pipes of high-voltage transmission lines above 10KV. Non excavation engineering HDPE drainage pipes are widely used in urban power cables, building water supply and drainage laying, and other fields.
HDPE non excavation pipes do not require excavation construction, and the pipes are hot-melt welded with flexible joints. The welded joints have high strength and can be dragged over long lengths with high traction.
Good toughness, with excellent resistance to ground subsidence and seismic performance. Commonly used pipes are divided into ordinary and reinforced types. The ordinary type is suitable for excavation and laying construction, as well as non excavation crossing construction with a burial depth of less than 4 meters; Reinforced type is used for non excavation crossing construction projects with a burial depth greater than 4 meters.
Advantages of HDPE power cable conduit
Has excellent electrical insulation properties.
Has high thermal deformation temperature and low-temperature impact performance.
Lightweight, smooth, with low friction resistance, suitable for hot melt welding and docking.
Long term use temperature -5~70 ℃.

Construction instructions for HDPE power cable conduit
During the transportation and construction of pipes, it is strictly prohibited to throw, hit, scratch, or expose them to sunlight at will.
During hot melt docking, the axis of the two pipes should be aligned, and the end face cutting should be vertical and flat.
Adjust the processing temperature, time, pressure, and climate conditions accordingly.
