鋁合金系列槽式電纜橋架作為現(xiàn)代電氣布線系統(tǒng)的核心組件，憑借其輕量化特性與優(yōu)異力學(xué)性能，在數(shù)據(jù)中心、軌道交通及工業(yè)廠房等領(lǐng)域得到廣泛應(yīng)用。該類產(chǎn)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(jié)構(gòu)，表面經(jīng)陽極氧化或噴塑處理，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(jié)構(gòu)優(yōu)勢(shì)

　　Material characteristics and structural advantages

　　鋁合金材質(zhì)密度僅為鋼材的三分之一，卻能達(dá)到相近的抗拉強(qiáng)度。6063-T5牌號(hào)鋁材的屈服強(qiáng)度超過150MPa，配合槽式結(jié)構(gòu)的閉合設(shè)計(jì)，可有效分散線纜重力，避免局部變形。橋架側(cè)板采用加筋處理，在保證剛性的同時(shí)降低材料厚度，典型規(guī)格側(cè)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(shè)計(jì)與安裝便捷性

　　Modular design and ease of installation

　　產(chǎn)品采用標(biāo)準(zhǔn)化節(jié)距設(shè)計(jì)，單節(jié)長(zhǎng)度通常為2米或3米，通過連接片與螺栓實(shí)現(xiàn)快速拼接。槽式結(jié)構(gòu)自帶蓋板，配合密封膠條可達(dá)到IP55防護(hù)等級(jí)，特別適用于粉塵或潮濕環(huán)境。吊裝系統(tǒng)配備彈簧減震器，可吸收振動(dòng)能量，降低對(duì)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(hù)

　　Heat dissipation performance and cable protection

　　槽體底部均勻分布散熱孔，孔徑與間距經(jīng)過流體力學(xué)模擬優(yōu)化，既能保證空氣對(duì)流，又避免小動(dòng)物侵入。實(shí)測(cè)數(shù)據(jù)顯示，在35℃環(huán)境溫度下，橋架內(nèi)部溫度比開放式敷設(shè)降低12-15℃，顯著延長(zhǎng)線纜使用壽命。對(duì)于大截面電纜，可選配分隔片實(shí)現(xiàn)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

　　陽極氧化膜層厚度達(dá)到AA15級(jí)標(biāo)準(zhǔn)，鹽霧試驗(yàn)超1000小時(shí)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(cè)試。在沿海高濕環(huán)境使用5年后，涂層完整率仍超過95%。特殊工況可選配導(dǎo)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(duì)特殊場(chǎng)景，可提供異形彎通、三通等非標(biāo)配件，小彎曲半徑達(dá)1.5倍橋架寬度。顏色方面除標(biāo)準(zhǔn)銀白、灰白外，可調(diào)配RAL色卡任意色系。對(duì)于電磁屏蔽要求，可內(nèi)襯鍍鋅鋼板形成復(fù)合結(jié)構(gòu)，屏蔽效能達(dá)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(zhì)量管控與檢測(cè)標(biāo)準(zhǔn)

　　Quality Control and Testing Standards

　　生產(chǎn)全程執(zhí)行GB/T 23639-2017標(biāo)準(zhǔn)，關(guān)鍵工序設(shè)置激光檢測(cè)工位。成品需通過承重試驗(yàn)，加載額定載荷1.5倍持續(xù)24小時(shí)，變形量≤0.2%。每批產(chǎn)品附帶檢測(cè)報(bào)告，包含材質(zhì)分析、涂層厚度、鹽霧試驗(yàn)等關(guān)鍵數(shù)據(jù)。

　　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.
