　　在光伏電站建設(shè)中，電纜橋架作為支撐、保護(hù)光伏直流線、控制線的核心輔材，其安裝質(zhì)量直接決定電站布線、設(shè)備穩(wěn)定運(yùn)行及工程驗(yàn)收通過率。據(jù)行業(yè)統(tǒng)計(jì)，40%的光伏電站驗(yàn)收返工，源于電纜橋架安裝不規(guī)范，其中防火封堵不到位、標(biāo)記缺失、防火涂料涂刷不達(dá)標(biāo)等問題為突出。山東電纜橋架憑借適配光伏場(chǎng)景的設(shè)計(jì)、嚴(yán)格的施工標(biāo)準(zhǔn)，成為光伏電站建設(shè)的優(yōu)選輔材，本文結(jié)合兆秀輔材業(yè)光伏橋架安裝實(shí)操經(jīng)驗(yàn)，詳解山東電纜橋架在光伏項(xiàng)目中的規(guī)范安裝全流程，助力施工單位規(guī)避驗(yàn)收風(fēng)險(xiǎn)、保障工程質(zhì)量。

　　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(duì)光伏戶外場(chǎng)景特性，在材質(zhì)選型、結(jié)構(gòu)設(shè)計(jì)上進(jìn)行專項(xiàng)優(yōu)化，選用耐候性強(qiáng)、防腐蝕的鋼材，可適應(yīng)戶外高低溫、雨雪、紫外線等復(fù)雜環(huán)境，使用壽命可達(dá)20年以上，遠(yuǎn)超普通電纜橋架10年的平均使用壽命，有效降低光伏電站后期運(yùn)維成本。同時(shí)，光伏專用山東電纜橋架采用模塊化設(shè)計(jì)，安裝便捷，可大幅提升施工進(jìn)度，相較于傳統(tǒng)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(xiàng)目中，山東電纜橋架安裝的核心的是“規(guī)范敷設(shè)、精準(zhǔn)封堵、嚴(yán)格防火”，每一個(gè)環(huán)節(jié)都需符合《建筑電氣工程施工質(zhì)量驗(yàn)收規(guī)范》GB 50303-2015要求，全程杜絕漏項(xiàng)、錯(cuò)項(xiàng)，具體施工流程及關(guān)鍵要點(diǎn)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:

　　，橋架敷設(shè)與固定完成后，需做好封蓋安裝與區(qū)域標(biāo)記。封蓋安裝需貼合橋架本體，確保縫隙嚴(yán)密，杜絕灰塵、雨水進(jìn)入橋架內(nèi)部，避免侵蝕電纜、影響導(dǎo)電性能；同時(shí)，需對(duì)光伏橋架的封堵區(qū)域進(jìn)行明確標(biāo)記，標(biāo)記需清晰、規(guī)范，便于后期巡檢、維護(hù)及驗(yàn)收，杜絕因標(biāo)記缺失導(dǎo)致的施工漏項(xiàng)、維護(hù)不便等問題，這也是光伏橋架安裝中易忽視卻關(guān)重要的環(huán)節(jié)。

　　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(yán)格遵循標(biāo)準(zhǔn)，守住消防底線。光伏橋架的封堵區(qū)域（尤其是直流線穿越處、橋架接口處），需采用符合規(guī)范的無機(jī)堵料（膨脹倍率≥250%）進(jìn)行嚴(yán)密封堵，確保無縫隙、無遺漏，防止火災(zāi)發(fā)生時(shí)火勢(shì)通過橋架蔓延；同時(shí)，封堵區(qū)域周邊1.5米范圍內(nèi)，必須均勻涂刷防火涂料，涂刷厚度不低于0.5mm，涂刷覆蓋率需達(dá)到100%，嚴(yán)禁漏刷、少刷，確保防火性能達(dá)標(biāo)，這是光伏電站消防驗(yàn)收的核心考核項(xiàng)。

　　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(guān)鍵要點(diǎn)。光伏直流線傳輸過程中，若封堵不嚴(yán)密，易出現(xiàn)水汽、灰塵侵入，導(dǎo)致線路短路、老化加速，甚引發(fā)事故。施工中，需采用光伏專用封堵材料，對(duì)直流線與橋架的連接處進(jìn)行精準(zhǔn)封堵，確保密封可靠，同時(shí)避免封堵材料擠壓線路，保障直流線傳輸順暢，兼顧性與實(shí)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(xiàng)目中的安裝，需全程遵循“先檢查、后安裝、再驗(yàn)收”的原則。安裝前，需檢查橋架材質(zhì)、規(guī)格是否符合設(shè)計(jì)要求，確保無變形、無破損、防腐涂層完好；安裝過程中，需實(shí)時(shí)把控封蓋安裝、標(biāo)記、防火封堵、涂料涂刷等細(xì)節(jié)，每完成一個(gè)環(huán)節(jié)，進(jìn)行專項(xiàng)檢查，及時(shí)整改問題；安裝完成后，需進(jìn)行驗(yàn)收，核查封堵質(zhì)量、防火涂料涂刷情況、標(biāo)記完整性，確保所有環(huán)節(jié)符合規(guī)范，避免因細(xì)節(jié)問題導(dǎo)致驗(yàn)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(guī)范與否，直接關(guān)系到光伏電站的長期穩(wěn)定運(yùn)行與消防。相較于普通電纜橋架，山東電纜橋架憑借適配光伏場(chǎng)景的優(yōu)勢(shì)、嚴(yán)格的質(zhì)量管控，以及規(guī)范的施工標(biāo)準(zhǔn)，有效解決了光伏橋架安裝中“封堵不嚴(yán)、防火不到位、標(biāo)記缺失”等行業(yè)痛點(diǎn)，助力施工單位提升施工效率、降低驗(yàn)收風(fēng)險(xiǎn)，同時(shí)為光伏電站的穩(wěn)定運(yùn)行筑牢基礎(chǔ)。

　　As a core component of auxiliary materials for photovoltaic power plants, the installation standards of cable trays in Shandong directly affect the long-term stable operation and fire safety of photovoltaic power plants. Compared with ordinary cable trays, Shandong cable trays have effectively solved industry pain points such as "lax sealing, inadequate fire prevention, and missing markings" in the installation of photovoltaic trays, thanks to their professional advantages in adapting to photovoltaic scenarios, strict quality control, and standardized construction standards. They help construction units improve construction efficiency, reduce acceptance risks, and lay a solid foundation for the safe and stable operation of photovoltaic power plants.
