◆ Product advantages

1. Material characteristics

The buried high-voltage power cable protection tube has excellent heat resistance and insulation performancePVC-UResin is the main material,PVC-UProducts are currently recognized as green and environmentally friendly products, and their excellent physical and chemical properties are increasingly being valued by the industry.PVC-UThe buried high-voltage power cable protection pipe is a hard straight solid wall pipe, with smooth and flat inner and outer walls, and a bright and eye-catching orange red color.

2. Heat resistance performance

PVC-UBuried high-voltage cable conduit is more common than ordinaryUPVCDouble walled corrugated pipe with increased heat resistance and temperature resistance15℃, can be in93In an environment above ℃, it remains non deformed and has sufficient strength.

3. Insulation performance

PVC-UThe buried high-voltage power cable protection pipe can withstand3High voltage above 10000 volts.

4. Compressive performance

PVC-UThe buried high-voltage power cable protection tube has undergone material modification, and the product's ring stiffness has reached10kpaThe ring stiffness of buried plastic pipes should be significantly higher than that of relevant national departments8kpaThe above regulations.

5. High impact resistance

Underground high-voltage power cable protection conduit0Can withstand temperatures up to ℃1kgHeavy hammer,2mThe high impact force fully reflects the low-temperature impact performance of the material, which is fully applicable to the requirements of construction environmental conditions.

⒍ Flame retardant performance

PVCandPVC-UThe materials have good flame retardant properties and can extinguish immediately upon ignition. especiallyPVC-UThe material, due to its significantly higher chlorine contentPVCSo the flame retardancy and smoke density index have been significantly improved.

7. Installation performance

The buried high-voltage power cable protection pipe is lightweight, high-strength, and has a simple construction and laying method. It can be excavated and buried at night, backfilled on the road surface, and opened to traffic as usual during the day; Adopting elastic sealing rubber ring socket connection, the installation and connection are convenient, fast, and have good sealing performance, which can prevent groundwater leakage and effectively protect the safety of power cable use.

Long service life

PVC-UThe material is corrosion resistant, anti-aging and has a long service life50Years or more.
