《建筑電氣與智能化通用規范》GB 55024-2022:6. 2. 2 室內潮濕場所的線纜明敷時，應符合下列規定：

　　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 應采用防潮防腐材料制造的導管或電纜橋架；

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

　　2 當采取金屬導管或電纜橋架時，應采取防潮防腐措施，且金屬導管壁厚不應小于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 當采用可彎曲金屬導管時，應選用防水重型的導管。條文說明：6. 2. 2 本條要求室內潮濕場所明敷的導管、電纜橋架必須采用防潮防腐材料制造或做防潮防腐處理。一旦導管或電纜橋架被腐蝕，將大大削弱其支撐和機械防護的能力，對供電有很大影響，因此需要對其防潮防腐要求進行明確。

　　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 室內潮濕場所明敷導管或電纜橋架，原則上優先選用防潮防腐材料制造的導管或電纜橋架，如不銹鋼導管、不銹鋼電纜橋架、燃燒性能分級為B1級的剛性塑料導管或高分子合金電纜橋架、晶須改性塑料電纜橋架或不銹鋼電纜橋架。

　　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 室內潮濕場所采用普通鋼導管和鋼制電纜橋架明敷時，需要采取防潮防腐措施，如采用防潮防腐漆做涂刷處理，且涂刷不少于3 次。且鋼導管的壁厚不應小于2.0mm, 鋼制電纜橋架板厚不應小于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 可彎曲金屬導管根據其產品標準要求，需要選用防水重型的導管。這條是強制性條文，應注意遵守。

　　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.
