　　In the construction of photovoltaic power stations, cable trays serve as the core auxiliary materials for supporting and protecting photovoltaic DC lines and control lines. Their installation quality directly determines the safety of power station wiring, stable operation of equipment, and project acceptance rate. According to industry statistics, 40% of photovoltaic power plant acceptance rework is due to improper installation of cable trays, with the most prominent issues being inadequate fireproof sealing, missing markings, and substandard fireproof coating application. Shandong cable trays have become the preferred auxiliary materials for photovoltaic power station construction due to their professional design and strict construction standards that are suitable for photovoltaic scenarios. This article combines the practical experience of installing photovoltaic trays in Zhaoxiu Auxiliary Materials Industry to explain in detail the standardized installation process of Shandong cable trays in photovoltaic projects, helping construction units avoid acceptance risks and ensure project quality.

　　山東電纜橋架針對光伏戶外場景特性，在材質選型、結構設計上進行專項優化，選用耐候性強、防腐蝕的優良鋼材，可適應戶外高低溫、雨雪、紫外線等復雜環境，使用壽命可達20年以上，優于普通電纜橋架10年的平均使用壽命，有效降低光伏電站后期運維成本。同時，光伏專用山東電纜橋架采用模塊化設計，安裝便捷出色，可大幅提升施工進度，相較于傳統橋架，安裝效率提升30%，適配各類光伏電站的布線需求。

　　Shandong cable trays have been specially optimized in material selection and structural design based on the characteristics of outdoor photovoltaic scenarios. High quality steel with strong weather resistance and corrosion resistance is selected, which can adapt to complex outdoor environments such as high and low temperatures, rain and snow, and ultraviolet radiation. The service life can reach more than 20 years, far exceeding the average service life of ordinary cable trays by 10 years, effectively reducing the later operation and maintenance costs of photovoltaic power plants. At the same time, the photovoltaic dedicated Shandong cable tray adopts a modular design, which is easy and efficient to install, and can greatly improve the construction progress. Compared with traditional trays, the installation efficiency is increased by 30%, and it is suitable for the wiring needs of various photovoltaic power stations.

　　光伏項目中，山東電纜橋架安裝的核心核心的是“規范敷設、合理封堵、嚴格防火”，每一個環節都需符合《建筑電氣工程施工質量驗收規范》GB 50303-2015要求，全程杜絕漏項、錯項，具體施工流程及關鍵要點如下：

　　In the photovoltaic project, the core focus of cable tray installation in Shandong is "standardized laying, precise sealing, and strict fire prevention". Each link must comply with the requirements of the "Code for Acceptance of Construction Quality of Building Electrical Engineering" GB 50303-2015, and eliminate omissions and errors throughout the process. The specific construction process and key points are as follows:

　　首先，橋架敷設與固定完成后，需核心做好封蓋安裝與區域標記。封蓋安裝需貼合橋架本體，確保縫隙嚴密，杜絕灰塵、雨水進入橋架內部，避免侵蝕電纜、影響導電性能；同時，需對光伏橋架的封堵區域進行明確標記，標記需清晰、規范，便于后期巡檢、維護及驗收，杜絕因標記缺失導致的施工漏項、維護不便等問題，這也是光伏橋架安裝中非常易忽視卻至關重要的環節。

　　Firstly, after the installation and fixation of the bridge frame, it is necessary to focus on the installation of covers and area marking. The installation of the cover should be closely attached to the bridge body to ensure tight gaps, prevent dust and rainwater from entering the interior of the bridge, and avoid corroding the cable and affecting its conductivity; At the same time, it is necessary to clearly mark the sealing area of the photovoltaic bridge, which should be clear and standardized, for easy inspection, maintenance and acceptance in the later stage, and to eliminate problems such as construction omissions and inconvenient maintenance caused by missing markings. This is also the most easily overlooked but crucial link in the installation of photovoltaic bridge.

　　其次，防火封堵與防火涂料涂刷需嚴格遵循標準，守住消防安全底線。光伏橋架的封堵區域（尤其是直流線穿越處、橋架接口處），需采用符合規范的無機堵料（膨脹倍率≥250%）進行嚴密封堵，確保無縫隙、無遺漏，防止火災發生時火勢通過橋架蔓延；同時，封堵區域周邊1.5米范圍內，建議均勻涂刷防火涂料，涂刷厚度不低于0.5mm，涂刷覆蓋率需達到100%，嚴禁漏刷、少刷，確保防火性能達標，這是光伏電站消防安全驗收的核心考核項。

　　Secondly, fireproof sealing and fireproof coating application must strictly follow the standards to maintain the bottom line of fire safety. The sealing area of the photovoltaic bridge (especially the DC line crossing and bridge interface) should be tightly sealed with inorganic sealing materials that meet the specifications (expansion ratio ≥ 250%) to ensure no gaps or omissions, and to prevent the spread of fire through the bridge in case of a fire; At the same time, within a radius of 1.5 meters around the sealed area, fireproof coating must be evenly applied with a thickness of not less than 0.5mm and a coverage rate of 100%. It is strictly prohibited to miss or brush less to ensure that the fireproof performance meets the standard. This is the core assessment item for the fire safety acceptance of photovoltaic power plants.

　　直流線封堵是光伏橋架安裝的另一關鍵要點。光伏直流線傳輸過程中，若封堵不嚴密，易出現水汽、灰塵侵入，導致線路短路、老化加速，甚至引發安全事故。施工中，需采用光伏專用封堵材料，對直流線與橋架的連接處進行合理封堵，確保密封可靠，同時避免封堵材料擠壓線路，保障直流線傳輸順暢，兼顧安全性與實用性。

　　DC line blocking is another key point in the installation of photovoltaic cable trays. During the transmission process of photovoltaic DC lines, if the sealing is not tight, it is easy for water vapor and dust to enter, causing short circuits, accelerated aging, and even safety accidents. During construction, it is necessary to use photovoltaic specific sealing materials to accurately seal the connection between the DC line and the bridge frame, ensuring reliable sealing while avoiding the compression of the line by the sealing materials, ensuring smooth transmission of the DC line, and balancing safety and practicality.

　　值得注意的是，山東電纜橋架在光伏項目中的安裝，需全程遵循“先檢查、后安裝、再驗收”的原則。安裝前，需檢查橋架材質、規格是否符合設計要求，確保無變形、無破損、防腐涂層完好；安裝過程中，需實時把控封蓋安裝、標記、防火封堵、涂料涂刷等細節，每完成一個環節，進行專項檢查，及時整改問題；安裝完成后，需進行多維度驗收，核心核查封堵質量、防火涂料涂刷情況、標記完整性，確保所有環節符合規范，避免因細節問題導致驗收返工。

　　It is worth noting that the installation of Shandong cable trays in photovoltaic projects must follow the principle of "inspection first, installation later, and acceptance later" throughout the process. Before installation, it is necessary to check whether the material and specifications of the bridge meet the design requirements, to ensure that there is no deformation, no damage, and the anti-corrosion coating is intact; During the installation process, it is necessary to control the installation, marking, fireproof sealing, coating and other details of the cover in real time. After each step is completed, a special inspection should be conducted to promptly rectify any problems; After installation, a comprehensive acceptance is required, with a focus on checking the quality of sealing, the application of fireproof coating, and the completeness of markings to ensure that all aspects comply with specifications and avoid rework due to details.

　　作為光伏電站輔材的核心組成部分，山東電纜橋架的安裝規范與否，直接關系到光伏電站的長期穩定運行與消防安全。相較于普通電纜橋架，山東電纜橋架憑借適配光伏場景的專業優勢、嚴格的質量管控，以及規范的施工標準，有效解決了光伏橋架安裝中“封堵不嚴、防火不到位、標記缺失”等行業痛點，助力施工單位提升施工效率、降低驗收風險，同時為光伏電站的安全穩定運行筑牢基礎。
