1. The insulation is corrosion-resistant and will not corrode after ten or twenty years of use;
2. Good flame retardancy. Generally, high-quality wire tubes have a flame retardant level of up to V0, which can extinguish immediately upon ignition and does not cause a sudden temperature rise after combustion like metal tubes.
3. PVC conduit material is lighter, easier to install, and more cost-effective.
4. PVC conduit can be used in conjunction with prefabricated bent pipes, without the need for manual bending, making it smoother to thread wires and keep them in a live state. In addition, if there are any problems, local wire replacement and maintenance can be carried out.
High quality PVC pipes have a service life of over 20 years and are more suitable for home decoration compared to metal pipes.
