CPVC Power and Communication Pipe Fittings CPVC power and communication pipes, also known as CPVC high-voltage power cable conduits, are widely used in the power and communication fields. Here's a detailed introduction: Product Definition and Manufacturing CPVC power and communication pipes are produced by reaction modification of polyvinyl chloride (PVC) resin, with chlorine content increased from 56.7% to 63-69%, primarily using the excellent heat resistance and insulation properties of PVC-C resin. Product Features 1. Appearance: Hard, straight, seamless pipes with smooth and even inner and outer walls, bright orange color, and striking appearance. 2. Heat Resistance: Higher heat resistance than standard UPVC double-walled corrugated pipes, with a 15℃ increase in heat resistance, maintaining shape at temperatures above 93℃ and sufficient strength. 3. Insulation: Can withstand voltages above 30,000V, effectively ensuring the safety of power and communication lines. 4. Pressure Resistance: Material modification results in a ring stiffness of 10kPa, significantly higher than the national standard of over 8kPa for buried plastic pipes. 5. High Impact Strength: Can withstand a 1kg hammer impact from a height of 2m at 0℃ temperatures, meeting the requirements of construction environment conditions. 6. Flame Retardancy: Both PVC and PVC-C materials have good flame retardancy, extinguishing upon removal from the flame. Especially PVC-C material, with its higher chlorine content, has a more significant improvement in flame retardancy and smoke density index. 7. Installation: Lightweight, high strength, and simple installation methods allow for night-time excavation and backfilling, enabling normal traffic during the day. Elastic sealing rubber rings for push-fit connections ensure easy, quick installation, good sealing performance, and prevent groundwater leakage, effectively protecting the safety of power and communication lines. 8. Long Service Life: Corrosion-resistant and aging-resistant materials provide a service life of over 50 years. 9. Environmental Characteristics: Recognized as a green and environmentally friendly product, its excellent physical and chemical properties are increasingly valued in the industry. Product Specifications Available sizes include 50, 63, 75, 90, 100, 110, 125, 156, 160, 181, 192, and 200mm (units in mm), with wall thickness ranging commonly from 3 to 8mm. The inner diameter of the pipe is generally determined by multiplying the cable's outer diameter by a factor of 1.5. Application Range - Power Industry: Widely used in urban power grid construction and renovation, municipal infrastructure projects, civil aviation airport construction, engineering park and residential area construction, traffic and road bridge construction, and urban streetlight cable laying, providing guidance and protection. - Communication Industry: Can be used as a protective pipe for communication lines, providing a stable and safe operating environment for communication cables, ensuring stable transmission of communication signals.
