铝合金系列槽式电缆桥架作为现代电气布线系统的核心组件，凭借其轻量化特性与优异力学性能，在数据中心、轨道交通及工业厂房等领域得到广泛应用。该类产品以铝合金型材为主体，通过精密挤压工艺形成U型槽体结构，表面经阳极氧化或喷塑处理，兼具耐腐蚀性与装饰性。

　　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.

　　材料特性与结构优势

　　Material characteristics and structural advantages

　　铝合金材质密度仅为钢材的三分之一，却能达到相近的抗拉强度。6063-T5牌号铝材的屈服强度超过150MPa，配合槽式结构的闭合设计，可有效分散线缆重力，避免局部变形。桥架侧板采用加筋处理，在保证刚性的同时降低材料厚度，典型规格侧板厚度2.0mm即可满足C类载荷要求。

　　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.

　　模块化设计与安装便捷性

　　Modular design and ease of installation

　　产品采用标准化节距设计，单节长度通常为2米或3米，通过连接片与螺栓实现快速拼接。槽式结构自带盖板，配合密封胶条可达到IP55防护等级，特别适用于粉尘或潮湿环境。吊装系统配备弹簧减震器，可吸收振动能量，降低对桥架本体的冲击载荷。

　　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.

　　散热性能与线缆保护

　　Heat dissipation performance and cable protection

　　槽体底部均匀分布散热孔，孔径与间距经过流体力学模拟优化，既能保证空气对流，又避免小动物侵入。实测数据显示，在35℃环境温度下，桥架内部温度比开放式敷设降低12-15℃，显著延长线缆使用寿命。对于大截面电缆，可选配分隔片实现分层布置，防止电磁干扰与热量堆积。

　　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.

　　表面处理与耐候性能

　　Surface treatment and weather resistance performance

　　阳极氧化膜层厚度达到AA15级标准，盐雾试验超1000小时无腐蚀。喷塑层采用聚酯粉末涂料，膜厚60-80μm，通过百格法附着力测试。在沿海高湿环境使用5年后，涂层完整率仍超过95%。特殊工况可选配导电氧化层，满足等电位连接要求。

　　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.

　　定制化解决方案

　　Customized solutions

　　针对特殊场景，可提供异形弯通、三通等非标配件，小弯曲半径达1.5倍桥架宽度。颜色方面除标准银白、灰白外，可调配RAL色卡任意色系。对于电磁屏蔽要求，可内衬镀锌钢板形成复合结构，屏蔽效能达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.

　　质量管控与检测标准

　　Quality Control and Testing Standards

　　生产全程执行GB/T 23639-2017标准，关键工序设置激光检测工位。成品需通过承重试验，加载额定载荷1.5倍持续24小时，变形量≤0.2%。每批产品附带检测报告，包含材质分析、涂层厚度、盐雾试验等关键数据。

　　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.
