Why do wires need to be passed through tubes?
In modern construction and home decoration, wire routing is a common construction step. Although many people may be confused by this practice, electrical conduits actually serve multiple important functions, including safety protection, ease of repair, and compliance with code requirements. This article will discuss in detail the reasons why wires pass through conduits, and display relevant hot topics through structured data.
1. The main reasons for wires passing through conduits

1.Security protection: Wire ducting can effectively prevent the risk of short circuit or fire caused by external damage to wires (such as extrusion, friction or rodent gnawing).
2.Fire performance: Pipe penetration materials usually have flame retardant properties, which can delay the spread of fire when a fire occurs and buy time for escape and rescue.
3.Easy to repair and replace: If there is a problem with the wire, the through-tube design allows maintenance personnel to easily pull out the old wire and replace it with a new one without damaging the wall or decoration.
4.Moisture-proof and corrosion-proof: In humid or corrosive environments, ducting can protect wires from moisture and chemicals, extending wire life.
5.Comply with specification requirements: The electrical installation codes of most countries and regions require that wires must pass through conduits to ensure construction quality and safety.

3. Common materials for wire ducting
The choice of material for wire ducting directly affects its performance and scope of application. The following are several common ducting materials and their characteristics:
| Material type | Advantages | Disadvantages | Applicable scenarios |
|---|---|---|---|
| PVC pipe | Low price, light weight, corrosion resistance | Lower compressive strength | Home decoration, dry environment |
| metal pipe | High compressive strength and good fire resistance | Higher price, easy to rust | Industrial sites, humid environments |
| bellows | Good flexibility and easy to bend | Average compressive strength | Complex wiring and temporary construction |
| PE pipe | Low temperature resistance and good insulation | Not resistant to high temperatures | Outdoor wiring, low temperature environment |
4. Precautions for construction of wire ducting
1.Pipe diameter selection: The diameter of the pipe should be greater than 60% of the cross-sectional area of the wire to ensure that the wire can pass through easily and leave space for heat dissipation.
2.bending radius: The bending radius of the pipe should not be less than 6 times the diameter of the pipe to avoid damage to the wire at the bend.
3.fixed spacing: The pipes should be fixed every 1-1.5 meters to prevent the pipes from loosening or sagging.
4.Waterproof treatment: In a humid environment, the interface of the pipe should be waterproof and sealed to prevent moisture from penetrating.
5.Grounding requirements: Metal pipes must be reliably grounded to prevent the risk of leakage.
5. Summary
Wire ducting is an indispensable part of electrical installation. It not only improves safety, but also extends the service life of wires and facilitates later maintenance. Choosing appropriate ducting materials and standardized construction methods are key to ensuring stable operation of the electrical system. I hope that through the introduction of this article, readers can have a deeper understanding of the importance of wire threading and pay attention to it in practical applications.
