　　槽寬>300mm且≤500mm，槽體厚度≥1.5mm

　　Slot width>300mm and ≤ 500mm, slot thickness ≥ 1.5mm

　　槽寬>500mm且≤800mm，槽體厚度≥2.0mm

　　Slot width>500mm and ≤ 800mm, slot thickness ≥ 2.0mm

　　槽寬>800mm，槽體厚度≥2.2mm

　　Slot width>800mm, slot body thickness ≥ 2.2mm

　　表面處理 ：

　　Surface treatment:

　　電纜橋架的表面處理應(yīng)符合相關(guān)標(biāo)準(zhǔn)，如熱浸鋅、冷鍍鋅、靜電噴塑等，以確保其耐腐蝕性能和使用壽命。

　　The surface treatment of cable trays should comply with relevant national standards, such as hot-dip galvanizing, cold galvanizing, electrostatic spraying, etc., to ensure their corrosion resistance and service life.

　　防火要求 ：

　　Fire prevention requirements:

　　在有防火要求的場所，電纜橋架應(yīng)采取防火隔離措施，使用防火材料制作，如復(fù)合環(huán)氧樹脂防腐阻燃型電纜橋架等。

　　In places with fire prevention requirements, cable trays should be equipped with fire isolation measures and made of fire-resistant materials, such as composite epoxy resin anti-corrosion and flame-retardant cable trays.

　　接地要求 ：

　　Grounding requirements:

　　電纜橋架系統(tǒng)應(yīng)具有可靠的電氣連接并接地，金屬電纜橋架及支架全長應(yīng)不少于2處與接地（PE）或接零（PEN）干線相連接，非鍍鋅電纜橋架間連接板的兩端跨接線銅芯接地線，接地線小允許截面積不小于4mm2。

　　The cable tray system should have reliable electrical connections and grounding. The total length of the metal cable tray and support should be connected to the grounding (PE) or neutral (PEN) main line at no less than 2 points. The two ends of the connecting plate between non galvanized cable trays should have a copper core grounding wire, and the minimum allowable cross-sectional area of the grounding wire should not be less than 4mm2.

　　安裝要求 ：

　　Installation requirements:

　　電纜橋架的安裝應(yīng)參照相關(guān)標(biāo)準(zhǔn)圖集，如《電纜橋架安裝》04D701-3，確保安裝質(zhì)量和性。

　　The installation of cable trays should refer to relevant standard drawings, such as "Cable Tray Installation" 04D701-3, to ensure installation quality and safety.

　　環(huán)境適應(yīng)性 ：

　　Environmental adaptability:

　　電纜橋架的選擇和安裝應(yīng)考慮環(huán)境條件，如常年平均氣溫、極端氣溫、空氣相對濕度、海拔高度、日照強度、風(fēng)速、地震烈度、污穢等級等，以確保在各種環(huán)境下都能正常工作。

　　The selection and installation of cable trays should consider environmental conditions, such as annual average temperature, extreme temperature, relative humidity, altitude, sunshine intensity, maximum wind speed, earthquake intensity, pollution level, etc., to ensure normal operation in various environments.

　　這些標(biāo)準(zhǔn)規(guī)范為電纜橋架的設(shè)計、制造、安裝和使用提供了詳細(xì)的技術(shù)指導(dǎo)和要求，確保了電纜橋架系統(tǒng)的性和可靠性。在實際應(yīng)用中，應(yīng)根據(jù)具體工程需求和相關(guān)標(biāo)準(zhǔn)進(jìn)行選擇和安裝。

　　These standard specifications provide detailed technical guidance and requirements for the design, manufacturing, installation, and use of cable trays, ensuring the safety and reliability of cable tray systems. In practical applications, selection and installation should be based on specific engineering requirements and relevant standards.
