济南电缆桥架：电缆桥架的标准规范你知道吗？
材质和制造要求 ：
Material and manufacturing requirements:
电缆桥架的材料应符合相关标准，如《钢制电缆桥架工程技术规程》T/CECS31-2017和《电控配电用电缆桥架》/T 10216-2013等，这些标准规定了电缆桥架所使用的金属材料、塑料材料等，并对其物理性能和化学性能进行了要求。同时，还规定了电缆桥架的制造工艺、加工精度、表面处理等要求。
The material of cable trays should comply with relevant national standards, such as the "Technical Specification for Steel Cable Tray Engineering" T/CECS31-2017 and the "Cable Tray for Electrical Control and Distribution" /T 10216-2013. These standards specify the metal and plastic materials used in cable trays and require their physical and chemical properties. At the same time, it also specifies the manufacturing process, processing accuracy, surface treatment and other requirements for cable trays.
尺寸和荷载 ：
Size and load:
电缆桥架的宽度、高度、槽宽和槽体厚度等尺寸应满足一定的要求，以确保电缆的敷设和运行。例如，钢制桥架的厚度与槽宽有关，具体规定如下：
The width, height, slot width, and slot thickness of cable trays should meet certain requirements to ensure the safe laying and operation of cables. For example, the thickness of steel cable trays is related to the width of the groove, and the specific regulations are as follows:
槽宽≤150mm，槽体厚度≥1.0mm
Slot width ≤ 150mm, slot body thickness ≥ 1.0mm
槽宽>150mm且≤300mm，槽体厚度≥1.2mm
Slot width>150mm and ≤ 300mm, slot thickness ≥ 1.2mm
槽宽>300mm且≤500mm，槽体厚度≥1.5mm
Slot width>300mm and ≤ 500mm, slot thickness ≥ 1.5mm
槽宽>500mm且≤800mm，槽体厚度≥2.0mm
Slot width>500mm and ≤ 800mm, slot thickness ≥ 2.0mm
槽宽>800mm，槽体厚度≥2.2mm
Slot width>800mm, slot body thickness ≥ 2.2mm
表面处理 ：
Surface treatment:
电缆桥架的表面处理应符合相关标准，如热浸锌、冷镀锌、静电喷塑等，以确保其耐腐蚀性能和使用寿命。
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:
在有防火要求的场所，电缆桥架应采取防火隔离措施，使用防火材料制作，如复合环氧树脂防腐阻燃型电缆桥架等。
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:
电缆桥架系统应具有可靠的电气连接并接地，金属电缆桥架及支架全长应不少于2处与接地（PE）或接零（PEN）干线相连接，非镀锌电缆桥架间连接板的两端跨接线铜芯接地线，接地线小允许截面积不小于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.
安装要求 ：
Installation requirements:
电缆桥架的安装应参照相关标准图集，如《电缆桥架安装》04D701-3，确保安装质量和性。
The installation of cable trays should refer to relevant standard drawings, such as "Cable Tray Installation" 04D701-3, to ensure installation quality and safety.
环境适应性 ：
Environmental adaptability:
电缆桥架的选择和安装应考虑环境条件，如常年平均气温、极端气温、空气相对湿度、海拔高度、日照强度、风速、地震烈度、污秽等级等，以确保在各种环境下都能正常工作。
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.
这些标准规范为电缆桥架的设计、制造、安装和使用提供了详细的技术指导和要求，确保了电缆桥架系统的性和可靠性。在实际应用中，应根据具体工程需求和相关标准进行选择和安装。
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.
