In home renovations or construction projects, the installation of polyvinyl chloride (PVC) insulated electrical wires is a crucial step concerning electrical safety and the lifespan of the wiring. Proper installation can effectively prevent future problems.
First, careful consideration of the installation route and environmental assessment is essential. According to national standards, PVC insulated wires should avoid corrosive gases, heat pipes, and other adverse environments. If too close to a heat source, reliable insulation measures must be taken. In damp areas or areas susceptible to mechanical damage, wires must be run through corrosion-resistant PVC pipes or metal conduits to prevent erosion and impact. It is particularly important to emphasize that directly burying insulated wires in cement or lime layers is strictly prohibited. Prolonged contact with alkaline substances and the shrinkage stress of cement can easily cause the insulation layer to age and crack, leading to electrical leakage accidents.
During construction, details cannot be overlooked. The bending radius of the wire should not be less than six times its outer diameter to avoid damage to the conductor or insulation layer due to forced bending. When laying wires in low-temperature environments (such as below 0°C), the insulation material is prone to brittle cracking; therefore, the wires should be preheated. For conduit laying, ensure the conduit openings are smooth or fitted with protective sleeves to prevent scratches on the insulation. All wire joints must be located inside junction boxes, ensuring secure connections and proper insulation. Joints must not be left inside conduits or walls for future inspection and maintenance.
After wiring is laid, proper fixing and protection are equally important. Wires must be securely fixed with conduit clamps, especially at terminals and bends, to prevent loosening. When laying wires inside walls susceptible to nails or pressure, use metal plates or rigid conduits for enhanced protection.
