Guide de sélection des tuyaux d’alimentation en CPVC

Choosing the right CPVC power pipes is essential to ensure the safety and stability of the power system. This article will briefly introduce several key factors to help you make the right choice.

1. Use environment

CPVC power pipes need to be selected according to the specific use environment. Par exemple, underground, indoor, outdoor, and high temperature or humid environments all have different requirements for pipe performance. Ensuring that the pipe can adapt to these conditions can ensure long-term safety.

2. Voltage requirements

Choose the right CPVC power pipe according to the rated voltage of the cable. The higher the voltage, the higher the inner diameter and performance requirements of the pipe. The right inner diameter can ensure that the cable has enough space to dissipate heat to avoid overheating and failure.

3. Performance requirements

– High temperature resistance: CPVC power pipes should be able to remain stable in high temperature environments of 93-110℃ without deformation or performance degradation.

– Corrosion resistance: The pipe should be able to resist corrosive substances such as acids and alkalis, especially in environments exposed to these chemicals, to ensure long-term safe operation.

– Insulation: High-voltage cable pipes must have excellent insulation properties and be able to withstand voltages above 30,000 volts to prevent current leakage.

– Flame retardancy: Select pipes with high flame retardancy, and the flame retardancy level should reach FV-0 to reduce the risk of fire.

4. Pipeline specifications

– Pipe diameter: The inner diameter of the power pipe should be at least 1.5 times the outer diameter of the cable to ensure smooth passage of the cable and sufficient heat dissipation space.

– Epaisseur de paroi: According to the pressure and use environment of the pipeline, select the appropriate wall thickness. The thicker the wall thickness, the higher the strength of the pipeline.

– Connection method: Common connection methods include socket connection and adhesive connection. Choose the connection method that best suits the construction site conditions to ensure safe installation.

5. Comprehensive cost

When choosing CPVC power pipes, in addition to paying attention to price, you should also consider the service life and quality of the product. CPVC power pipes can usually be used for more than 50 années. Choosing high-quality products can reduce the cost of later maintenance and replacement.

Summary
The selection of CPVC power pipes requires comprehensive consideration of the use environment, voltage requirements, pipeline performance and cost. Following these points can help you find safe, reliable, economical and practical power pipe products.
