《建筑电气与智能化通用规范》GB 55024-2022:6. 2. 2 室内潮湿场所的线缆明敷时，应符合下列规定：

　　GB 55024-2022:6.2.2 General Code for Electrical and Intelligent Construction of Buildings: When laying cables in damp indoor areas, the following regulations should be followed:

　　1 应采用防潮防腐材料制造的导管或电缆桥架；

　　1. Conduits or cable trays made of moisture-proof and anti-corrosion materials should be used;

　　2 当采取金属导管或电缆桥架时，应采取防潮防腐措施，且金属导管壁厚不应小于2.0mm;

　　When using metal conduits or cable trays, moisture-proof and anti-corrosion measures should be taken, and the wall thickness of the metal conduit should not be less than 2.0mm;

　　3 当采用可弯曲金属导管时，应选用防水重型的导管。条文说明：6. 2. 2 本条要求室内潮湿场所明敷的导管、电缆桥架必须采用防潮防腐材料制造或做防潮防腐处理。一旦导管或电缆桥架被腐蚀，将大大削弱其支撑和机械防护的能力，对供电有很大影响，因此需要对其防潮防腐要求进行明确。

　　When using bendable metal conduits, waterproof heavy-duty conduits should be selected. Article description: 6 two This provision requires that conduits and cable trays installed in damp indoor areas must be made of moisture-proof and anti-corrosion materials or treated with moisture-proof and anti-corrosion measures. Once the conduit or cable tray is corroded, its support and mechanical protection capabilities will be greatly weakened, which will have a significant impact on power supply safety. Therefore, it is necessary to clarify its moisture-proof and anti-corrosion requirements.

　　1 室内潮湿场所明敷导管或电缆桥架，原则上优先选用防潮防腐材料制造的导管或电缆桥架，如不锈钢导管、不锈钢电缆桥架、燃烧性能分级为B1级的刚性塑料导管或高分子合金电缆桥架、晶须改性塑料电缆桥架或不锈钢电缆桥架。

　　When laying conduits or cable trays in damp indoor areas, it is generally preferred to use conduits or cable trays made of moisture-proof and anti-corrosion materials, such as stainless steel conduits, stainless steel cable trays, rigid plastic conduits or polymer alloy cable trays with a combustion performance rating of B1, whisker modified plastic cable trays or stainless steel cable trays.

　　2 室内潮湿场所采用普通钢导管和钢制电缆桥架明敷时，需要采取防潮防腐措施，如采用防潮防腐漆做涂刷处理，且涂刷不少于3 次。且钢导管的壁厚不应小于2.0mm, 钢制电缆桥架板厚不应小于1.5mm 。

　　When ordinary steel conduits and steel cable trays are installed in damp indoor areas, moisture-proof and anti-corrosion measures should be taken, such as using moisture-proof and anti-corrosion paint for coating treatment, and coating at least 3 times. The wall thickness of the steel conduit should not be less than 2.0mm, and the thickness of the steel cable tray plate should not be less than 1.5mm.

　　3 可弯曲金属导管根据其产品标准要求，需要选用防水重型的导管。这条是强制性条文，应注意遵守。

　　According to the product standard requirements, waterproof heavy-duty conduits need to be selected for the 3 bendable metal conduits. This is a mandatory provision, and attention should be paid to compliance.
