Currently, PVC-C power cable conduit is primarily used as a high-voltage cable conduit, and its quality is crucial to residents' safety. Recent incidents involving digging up high-voltage cables during renovation projects have led to accidents. Therefore, strict adherence to production standards and processes is crucial during the production of PVC-C power cable conduit, with no room for error at any stage. So, what are the production standards for PVC-C power cable conduit? What is the production process?
VC-C power cable conduit, also known as CPVC high-voltage power cable sheathing, is primarily made of PVC-C resin, blended with additives such as stabilizers and impact agents. This product features high strength, excellent flexibility, high-temperature resistance, corrosion resistance, flame retardancy, excellent insulation properties, pollution-free operation, resistance to aging, lightweight construction, and ease of installation. The PVC-C power cable conduit produced by Dengquan Plastic Technology (Hunan) Co., Ltd. has undergone national and provincial testing, appraisal, and certification, meeting or exceeding the performance standards of similar domestic products. This product significantly outperforms traditional asbestos cable conduit and ordinary PVC pipe, making it an ideal alternative to traditional power cable sheathing.
As a new type of conduit, PVC-C power cable conduit exhibits the following key performance characteristics:
1. Material Properties
CPVC power conduit is primarily made of PVC-C resin, which boasts excellent heat resistance and insulation properties. CPVC products are recognized as green and environmentally friendly products, and their excellent physical and chemical properties are increasingly valued by the industry.
CPVC power pipe is a rigid, straight, solid-wall pipe with smooth inner and outer surfaces and a bright, eye-catching orange-red color.
2. Insulation Performance
CPVC power pipe can withstand high voltages exceeding 30,000 volts.
3. Heat Resistance
CPVC power pipe has a heat resistance 15°C higher than the conventional UPVC double-wall corrugated pipe. It can withstand temperatures above 93°C without deformation and possesses sufficient strength.
4. High Impact Resistance
CPVC power pipe can withstand a 1kg hammer impact at a height of 2m at 0°C, demonstrating that its low-temperature impact resistance is fully compatible with construction conditions.
5. Installation Performance
CPVC power pipe is lightweight, high-strength, and simple to install. Excavation and backfilling can be performed at night, allowing for normal traffic during the day. Its socket-and-socket connection with elastic sealing rubber rings makes installation and connection quick and easy, with excellent sealing performance, preventing groundwater leakage and effectively protecting the safety of power cables.
6. Compressive Strength
CPVC power pipe has undergone material modification, achieving a ring stiffness of 1 kN, significantly exceeding the national standard for buried plastic pipes, which requires a ring stiffness of at least 8 kN.
7. Long Service Life
CPVC power pipe is corrosion-resistant and aging-resistant, with a service life of over 50 years.
8. Flame Retardant Properties
Both PVC and PVC-C have excellent flame-retardant properties and extinguish instantly when away from flames. PVC-C, in particular, has significantly higher chlorine content than PVC, resulting in significantly improved flame retardancy and smoke density.
