The advantages of Rigid Aluminum Conduit in electrical wiring are mainly reflected in the following aspects, especially suitable for specific engineering scenarios:
1. Lightweight and easy to install
Only one-third the weight of steel conduits: Aluminum has a low density (about 2.7g/cm ³), making it easier to handle and install, especially suitable for high-altitude operations or long-distance laying.
No need for heavy tools: can be quickly cut with aluminum specific cutting tools, with flexible bending radius (can be operated by manual pipe benders).
2. Strong corrosion resistance
Natural corrosion resistance: The aluminum surface forms a dense oxide film (Al ₂ O3), which resists moisture, salt spray, and chemical gases (such as chemical plants and coastal areas).
No need for coating protection: Compared to galvanized steel conduits, they are less prone to rusting and have lower maintenance costs when exposed to outdoor or humid environments for a long time.
3. Conductivity and Grounding Advantages
High conductivity: Aluminum has a conductivity five times that of steel and can also serve as a grounding conductor (subject to local electrical regulations such as NEC 250.118), reducing the need for additional grounding wires.
Anti electromagnetic interference: The metal shielding feature can block external electromagnetic interference and protect sensitive circuits.
4. Temperature resistance and fire resistance performance
High temperature resistance: The working temperature range is wide (-40 ° C to 150 ° C), suitable for high-temperature workshops or outdoor exposure environments.
Flame retardancy: Aluminum has a melting point of approximately 660 ° C and does not ignite upon contact with fire, meeting UL 6 fire protection standards.
5. Economy&Environmental Protection
Low lifecycle cost: Although the initial purchase price may be higher than PVC pipes, they are maintenance free for a long time and have a lifespan of over 30 years.
100% recyclable: The aluminum recycling rate is as high as 95%, which meets the requirements of LEED certification for green buildings.
Applicable scenarios
Industrial sector: chemical plants, refineries, food processing plants (corrosion resistance requirements)
Outdoor engineering: solar power station, bridge, dock (salt spray resistant)
Commercial buildings: data centers, hospitals (electromagnetic shielding requirements)
precautions
Galvanic corrosion: Avoid direct contact with copper or stainless steel and use insulated joints or compatible fittings.
Mechanical strength: The impact resistance is slightly lower than that of steel conduits. For heavy machinery areas, it is recommended to choose thicker models .
By combining the advantages of lightweight, corrosion resistance, and grounding, Rigid Aluminum Conduit can significantly improve wiring efficiency and system reliability in complex environments.
