　　Jinan cable tray: full analysis of photovoltaic special production, 2-meter standard section+anti-corrosion selection is the core

　　在濟南及魯中地區(qū)的工商業(yè)、戶用光伏電站建設中，電纜橋架作為線纜承載的核心部件，其制作工藝、材質選型與配件適配，直接關系橋架使用壽命、線路和電站穩(wěn)定性。光伏橋架并非通用款型，需結合本地氣候、戶外工況量身制作，不同于普通室內橋架，光伏專用款更側重耐腐蝕性、戶外耐用性與安裝便捷性。本文從實用制作思路出發(fā)，詳解光伏橋架的規(guī)格設定、材質選型、配件搭配及異形件制作，梳理一套適配濟南本地項目的標準化制作邏輯，兼顧實用性、合規(guī)性與性價比。

　　In the construction of industrial, commercial, and household photovoltaic power stations in Jinan and Luzhong areas, cable trays serve as the core components for cable carrying. The manufacturing process, material selection, and accessory adaptation of cable trays directly affect the service life of cable trays, line safety, and power station stability. Photovoltaic cable trays are not universal models and need to be tailored to local climate and outdoor conditions. Unlike ordinary indoor cable trays, photovoltaic specific models focus more on corrosion resistance, outdoor durability, and installation convenience. Starting from practical production ideas, this article provides a detailed explanation of the specification setting, material selection, accessory matching, and production of irregular parts for photovoltaic cable trays. It outlines a standardized production logic that is suitable for local projects in Jinan, taking into account practicality, compliance, and cost-effectiveness.

　　光伏橋架制作的首要核心是**標準化規(guī)格設定**，行業(yè)通用且適配光伏項目的為**2米一節(jié)**的標準段，這是經過大量工程驗證的規(guī)格。2米標準段便于運輸、吊裝與現(xiàn)場拼接，不會因過長導致運輸變形，也不會因過短增加拼接工作量，提升安裝效率，同時受力均勻，承重穩(wěn)定性更強，適配屋頂、地面、戶外廊道等各類光伏場景。制作時嚴格按照2米每節(jié)裁切基材，尺寸誤差控制在±2mm以內，保證后續(xù)拼接無縫隙、安裝橫平豎直，避免尺寸偏差影響整體布線與屋面防水。

　　The primary core of photovoltaic bridge production is standardized specification setting. The industry standard segment that is universally applicable and most suitable for photovoltaic projects is a 2-meter-long standard section, which has been extensively verified through engineering to be the optimal specification. The 2-meter standard section is convenient for transportation, lifting, and on-site splicing. It will not deform during transportation due to being too long, nor will it increase the workload of splicing due to being too short, thus improving installation efficiency. At the same time, it has uniform force distribution and stronger load-bearing stability, and is suitable for various photovoltaic scenarios such as roofs, floors, and outdoor corridors. Strictly cut the substrate according to 2 meters per section during production, with a size error controlled within ± 2mm, to ensure seamless splicing and installation in both horizontal and vertical directions, and to avoid size deviations affecting overall wiring and roof waterproofing.

　　材質選型是光伏橋架制作的關鍵，直接決定耐腐蝕性與使用壽命，結合濟南夏季多雨潮濕、冬季溫差大、部分近郊區(qū)域土壤含鹽量高的氣候特點，優(yōu)先選用三大防腐材質，淘汰普通冷軋板與烤漆款型。**熱浸鋅橋架**，鋅層厚度≥85μm，中性鹽霧測試可達1000小時無紅銹，耐潮濕、抗老化，適配絕大多數(shù)濟南光伏項目；其次是**鋅鋁鎂橋架**，防腐性能是普通熱浸鋅的2-3倍，切口可自修復，尤其適合沿海近郊、高濕戶外場景，后期運維成本更低；再者是**6063-T5鋁合金橋架**，重量輕、無渦流損耗，耐腐蝕且不生銹，適合屋頂分布式光伏，減輕屋面承重壓力，這三類材質是濟南光伏橋架的主流選型。

　　Material selection is the key to the production of photovoltaic bridge frames, which directly determines their corrosion resistance and service life. Considering the climate characteristics of Jinan, such as rainy and humid summers, large temperature differences in winter, and high soil salt content in some suburban areas, the three major anti-corrosion materials are preferred, and ordinary cold-rolled plates and baked paint styles are eliminated. The first choice is * * hot-dip galvanized cable tray * *, the thickness of zinc layer is ≥ 85 μ m, neutral salt spray test can reach 1000 hours without red rust, moisture resistance, anti-aging, suitable for most of Jinan PV projects; Next is the * * Zinc Aluminum Magnesium Bridge * *, which has 2-3 times the anti-corrosion performance of ordinary hot-dip galvanizing. The cut can be self repaired, especially suitable for coastal suburbs and high humidity outdoor scenes, with lower maintenance costs in the later stage; Furthermore, the 6063-T5 aluminum alloy bridge frame is lightweight, free from eddy current losses, corrosion-resistant, and rust resistant, making it suitable for distributed photovoltaic systems on roofs and reducing roof load-bearing pressure. These three types of materials are the mainstream choices for photovoltaic bridge frames in Jinan.

　　橋架制作完成后，**連接配件與工藝**是保障整體穩(wěn)定性的核心，標準2米段之間需采用專用連接片配合編織線雙重連接。常規(guī)連接片負責機械固定，保證兩段橋架拼接牢固、不松動、不變形；編織線為接地跨接專用，采用銅質編織帶，實現(xiàn)橋架整體電氣連通，形成完整接地通路，滿足光伏電氣規(guī)范，接地電阻≤4Ω，杜絕靜電積累隱患，雙重連接既保障結構穩(wěn)固，又符合電氣要求，是光伏橋架制作的必備工藝。

　　After the completion of the bridge frame production, * * connecting accessories and processes * * are the core to ensure overall stability. Special connecting pieces and braided wires need to be used for double connection between standard 2-meter sections. The conventional connecting piece is responsible for mechanical fixation, ensuring that the two sections of the bridge are firmly connected, not loose, and not deformed; Braided wire is specifically designed for grounding bridging, using copper braided tape to achieve overall electrical connection of the bridge, forming a complete grounding path that meets photovoltaic electrical safety regulations. The grounding resistance is ≤ 4 Ω, eliminating the hidden danger of static electricity accumulation. Dual connection ensures structural stability and meets electrical safety requirements, making it an essential process for the production of photovoltaic bridge.

　　光伏項目布線涉及轉彎、爬坡、變徑，因此異形件制作是橋架制作的重要補充，常用款型為爬坡彎、直角彎、水平三通，制作工藝簡單但需規(guī)范。轉彎處嚴禁現(xiàn)場直角裁切，需提前預制圓弧彎頭，圓弧半徑≥電纜外徑的10倍，避免劃傷電纜絕緣層；爬坡彎角度根據(jù)屋面坡度定制，常見15°、30°兩種，保證線纜平緩過渡；所有異形件均采用與標準段同款材質、同等厚度基材制作，防腐處理同步到位，確保整體性能一致。

　　The wiring of photovoltaic projects involves turning, climbing, and reducing diameters, so the production of irregular parts is an important supplement to the production of cable trays. Common types include climbing bends, right angle bends, and horizontal tees, with simple but standardized production processes. It is strictly prohibited to cut at right angles on site at the turning point. It is necessary to prefabricate curved bends in advance, with a radius of no less than 10 times the outer diameter of the cable, to avoid scratching the insulation layer of the cable; The climbing and bending angles are customized according to the roof slope, commonly 15 ° and 30 °, to ensure a smooth transition of cables; All irregular parts are made of the same material and substrate thickness as the standard section, and anti-corrosion treatment is synchronized to ensure consistent overall performance.

　　濟南光伏電纜橋架制作，核心就是把控2米標準段規(guī)格、優(yōu)選防腐材質、規(guī)范連接工藝、精準制作異形件，全程圍繞戶外耐腐、安裝便捷、電氣三大核心。摒棄劣質材質與粗放制作，遵循標準化制作邏輯，既能適配濟南本地氣候與光伏項目需求，又能延長橋架使用壽命，減少后期銹蝕、變形、漏水等問題，為光伏電站線纜運行筑牢基礎，實現(xiàn)一次制作、長期穩(wěn)定使用。

　　The core of Jinan photovoltaic cable tray production is to control the 2-meter standard section specifications, select anti-corrosion materials, standardize connection processes, and accurately produce irregular parts. The whole process revolves around the three core aspects of outdoor corrosion resistance, easy installation, and electrical safety. Abandoning inferior materials and rough production, following standardized production logic, it can not only adapt to the local climate and photovoltaic project needs in Jinan, but also extend the service life of the bridge, reduce problems such as corrosion, deformation, and water leakage in the later stage, and lay a solid foundation for the safe operation of photovoltaic power station cables, achieving one-time production and long-term stable use.
