鋁合金系列槽式電纜橋架作為現代電氣布線系統的核心組件，憑借其輕量化特性與優異力學性能，在數據中心、軌道交通及工業廠房等領域得到廣泛應用。該類產品以鋁合金型材為主體，通過精密擠壓工藝形成U型槽體結構，表面經陽出色氧化或噴塑處理，兼具耐腐蝕性與裝飾性。

　　Aluminum alloy series trough cable trays, as the core components of modern electrical wiring systems, have been widely used in data centers, rail transit, industrial plants and other fields due to their lightweight characteristics and excellent mechanical properties. This type of product is mainly made of aluminum alloy profiles, which are formed into a U-shaped groove structure through precision extrusion technology. The surface is treated with anodizing or spray coating, and has both corrosion resistance and decorative properties.

　　材料特性與結構優勢

　　Material characteristics and structural advantages

　　鋁合金材質密度僅為鋼材的三分之一，卻能達到相近的抗拉強度。6063-T5牌號鋁材的屈服強度超過150MPa，配合槽式結構的閉合設計，可有效分散線纜重力，避免局部變形。橋架側板采用加筋處理，在保證剛性的同時降低材料厚度，典型規格側板厚度2.0mm即可滿足C類載荷要求。

　　The density of aluminum alloy material is only one-third of that of steel, but it can achieve similar tensile strength. The yield strength of 6063-T5 grade aluminum exceeds 150MPa, and with the closed design of the groove structure, it can effectively disperse the gravity of the cable and avoid local deformation. The side panels of the bridge are reinforced to reduce material thickness while ensuring rigidity. A typical specification of 2.0mm thickness for the side panels is sufficient to meet Class C load requirements.

　　模塊化設計與安裝便捷性

　　Modular design and ease of installation

　　產品采用標準化節距設計，單節長度通常為2米或3米，通過連接片與螺栓實現快速拼接。槽式結構自帶蓋板，配合密封膠條可達到IP55防護等級，非常適用于粉塵或潮濕環境。吊裝系統配備彈簧減震器，可吸收振動能量，降低對橋架本體的沖擊載荷。

　　The product adopts a standardized pitch design, with a single section length usually 2 or 3 meters, and is quickly assembled through connecting pieces and bolts. The groove structure comes with a cover plate and, when combined with sealing strips, can achieve an IP55 protection level, making it particularly suitable for dusty or humid environments. The lifting system is equipped with spring shock absorbers, which can absorb vibration energy and reduce the impact load on the bridge body.

　　散熱性能與線纜保護

　　Heat dissipation performance and cable protection

　　槽體底部均勻分布散熱孔，孔徑與間距經過流體力學模擬優化，既能保證空氣對流，又避免小動物侵入。實測數據顯示，在35℃環境溫度下，橋架內部溫度比開放式敷設降低12-15℃，顯著延長線纜使用壽命。對于大截面電纜，可選配分隔片實現分層布置，防止電磁干擾與熱量堆積。

　　The bottom of the tank is uniformly distributed with heat dissipation holes, and the aperture and spacing are optimized through fluid dynamics simulation, which can ensure air convection and avoid small animal invasion. Actual test data shows that at an ambient temperature of 35 ℃, the internal temperature of the cable tray is reduced by 12-15 ℃ compared to open laying, significantly extending the service life of the cable. For large section cables, partition plates can be selected for layered arrangement to prevent electromagnetic interference and heat accumulation.

　　表面處理與耐候性能

　　Surface treatment and weather resistance performance

　　陽出色氧化膜層厚度達到AA15級標準，鹽霧試驗超1000小時無腐蝕。噴塑層采用聚酯粉末涂料，膜厚60-80μm，通過百格法附著力測試。在沿海高濕環境使用5年后，涂層完整率仍超過95%。特殊工況可選配導電氧化層，滿足等電位連接要求。

　　The thickness of the anodized film layer meets the AA15 standard, and there is no corrosion after more than 1000 hours of salt spray test. The spray coating layer is made of polyester powder coating with a film thickness of 60-80 μ m, and has passed the hundred grid adhesion test. After 5 years of use in high humidity coastal environments, the coating integrity rate still exceeds 95%. Special working conditions can be equipped with a conductive oxide layer to meet the requirements of equipotential bonding.

　　定制化解決方案

　　Customized solutions

　　針對特殊場景，可提供異形彎通、三通等非標配件，非常小彎曲半徑達1.5倍橋架寬度。顏色方面除標準銀白、灰白外，可調配RAL色卡任意色系。對于電磁屏蔽要求，可內襯鍍鋅鋼板形成復合結構，屏蔽效能達60dB以上。

　　For special scenarios, non-standard accessories such as irregular bends and tees can be provided, with a minimum bending radius of 1.5 times the width of the bridge. In terms of color, in addition to standard silver white and gray white, RAL color cards can be adjusted to any color scheme. For electromagnetic shielding requirements, a composite structure can be formed by lining galvanized steel plates, with a shielding efficiency of over 60dB.

　　質量管控與檢測標準

　　Quality Control and Testing Standards

　　生產全程執行GB/T 23639-2017標準，關鍵工序設置激光檢測工位。成品需通過承重試驗，加載至額定載荷1.5倍持續24小時，變形量≤0.2%。每批產品附帶檢測報告，包含材質分析、涂層厚度、鹽霧試驗等關鍵數據。

　　The entire production process follows the GB/T 23639-2017 standard, and key processes are equipped with laser detection stations. The finished product needs to pass a load-bearing test, loaded to 1.5 times the rated load for 24 hours, with a deformation of ≤ 0.2%. Each batch of products comes with a testing report, which includes key data such as material analysis, coating thickness, and salt spray testing.
