PVC-U power and communication conduits are manufactured from flame-retardant, insulated PVC compound, providing high dielectric strength to prevent current leakage, short circuits and arc breakdown.

High compressive and impact strength, together with excellent weather and soil corrosion resistance, make the conduit suitable for direct burial under roadways and developed areas, protecting cables from mechanical damage. Heat-resistant and self-extinguishing, it ensures high safety performance. Installation uses socket solvent cement joints for low-cost, efficient construction.

Applications include urban underground power networks, residential electrical and communication cabling, street lighting and traffic signal ducts, highway communication conduits, rail transit low-voltage systems and industrial park cable protection.

Notes on pipelines：

1. Made of flame-retardant PVC-U material, with good insulation performance, used for power and communication cable buried protection, prevent electric leakage and short circuit.

2. The bending radius shall not be less than 12 times the pipe outer diameter, prohibit forced bending causing pipe cracking, ensure smooth cable threading.

3. Adopt socket adhesive connection, operate in strict accordance with standards, ensure joint firmness and insulation sealing.

4. Buried in road and green belt areas, avoid heavy pressure and sharp object impact; do not stack heavy objects on the pipeline surface.

5. Prohibit use in high-temperature and strong corrosion environments, avoid material aging and insulation performance degradation.

6. During construction, prevent sand and debris from entering the pipe, block the pipe mouth in time after laying to facilitate later cable threading.
