          山東電纜橋架:潮濕環(huán)境如地下室衛(wèi)生間該選哪種材質(zhì)的橋架

            《建筑電氣與智能化通用規(guī)范》GB 55024-2022:6. 2. 2 室內(nèi)潮濕場(chǎng)所的線纜明敷時(shí),應(yīng)符合下列規(guī)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:base64_image

            1 應(yīng)采用防潮防腐材料制造的導(dǎo)管或電纜橋架;

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

            2 當(dāng)采取金屬導(dǎo)管或電纜橋架時(shí),應(yīng)采取防潮防腐措施,且金屬導(dǎo)管壁厚不應(yīng)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(dāng)采用可彎曲金屬導(dǎo)管時(shí),應(yīng)選用防水重型的導(dǎo)管。條文說明:6. 2. 2 本條要求室內(nèi)潮濕場(chǎng)所明敷的導(dǎo)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(dǎo)管或電纜橋架被腐蝕,將大大削弱其支撐和機(jī)械防護(hù)的能力,對(duì)供電有很大影響,因此需要對(duì)其防潮防腐要求進(jìn)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(nèi)潮濕場(chǎng)所明敷導(dǎo)管或電纜橋架,原則上優(yōu)先選用防潮防腐材料制造的導(dǎo)管或電纜橋架,如不銹鋼導(dǎo)管、不銹鋼電纜橋架、燃燒性能分級(jí)為B1級(jí)的剛性塑料導(dǎo)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(nèi)潮濕場(chǎng)所采用普通鋼導(dǎo)管和鋼制電纜橋架明敷時(shí),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(dǎo)管的壁厚不應(yīng)小于2.0mm, 鋼制電纜橋架板厚不應(yīng)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(dǎo)管根據(jù)其產(chǎn)品標(biāo)準(zhǔn)要求,需要選用防水重型的導(dǎo)管。這條是強(qiáng)制性條文,應(yīng)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.
