1、室內(nèi)環(huán)境

1. Indoor environment

①. 一般可選擇鋼質(zhì)或鋁質(zhì)普通型橋架,槽式或托盤式結(jié)構(gòu)均可。

①.  Generally, steel or aluminum ordinary cable trays can be selected, and groove or tray structures are both acceptable.

②. 如需美觀,可以選擇裝飾型鋼橋架。

②.  For aesthetics, decorative steel bridge frames can be chosen.

③. 公共場所大跨距(>3米)情況下,應(yīng)選用承重能力較強的復(fù)合型橋架。

③.  In public places with large spans (>3 meters), composite cable trays with strong load-bearing capacity should be selected.

2、腐蝕環(huán)境

2. Corrosive environment

①. 應(yīng)優(yōu)先選擇玻璃鋼、環(huán)氧樹脂或熱浸鍍鋅處理的鋼質(zhì)橋架。避免使用普通鋼質(zhì)。

①.  Steel cable trays treated with fiberglass, epoxy resin, or hot-dip galvanizing should be given priority. Avoid using ordinary steel.

②. 橋架附件也應(yīng)采用相應(yīng)防腐材料。

②.  The accessories of the bridge should also use corresponding anti-corrosion materials.

③. 戶外腐蝕環(huán)境嚴(yán)重的,必須選用復(fù)合型環(huán)氧樹脂橋架或經(jīng)熱浸鋅處理的鋼質(zhì)型材。

③.  For outdoor environments with severe corrosion, composite epoxy resin cable trays or hot-dip galvanized steel profiles must be selected.

④. 熱浸鍍鋅處理可以提高鋼質(zhì)橋架的抗腐蝕能力,適用于中等腐蝕環(huán)境。但在強腐蝕條件下,仍應(yīng)優(yōu)先使用玻璃鋼或環(huán)氧樹脂材質(zhì)。

④.  Hot dip galvanizing treatment can improve the corrosion resistance of steel cable trays and is suitable for moderate corrosive environments. However, under strong corrosive conditions, fiberglass or epoxy resin materials should still be prioritized for use.

⑤. 腐蝕環(huán)境下不建議使用普通冷軋鋼板或烤漆處理的橋架。

⑤.  It is not recommended to use ordinary cold-rolled steel plates or painted bridge frames in corrosive environments.

3、火災(zāi)高危環(huán)境

3. High risk fire environment

①. 應(yīng)選用阻燃型橋架,如環(huán)氧樹脂或玻璃鋼材質(zhì)。

①.  Flame retardant cable trays, such as epoxy resin or fiberglass material, should be selected.

②. 避免使用普通鋼質(zhì)或鋁質(zhì)橋架。

②.  Avoid using ordinary steel or aluminum cable trays.

③. 大跨距情況下,阻燃等級高的復(fù)合型橋架。

③.  In the case of large spans, composite cable trays with high flame retardant ratings are preferred.

4、室外環(huán)境

4. Outdoor environment

①. 宜密封蓋板的復(fù)合型橋架,如玻璃鋼、鋼管套型等。這可以提供輕量化及優(yōu)異的抗腐蝕性能。

①.  It is advisable to choose composite cable trays with sealed cover plates, such as fiberglass and steel pipe sleeve types. This can provide lightweight and excellent corrosion resistance.

②. 也可以選擇經(jīng)過熱浸鋅處理的鋼質(zhì)開口型或封閉型橋架。熱浸鋅可提高橋架抗腐蝕性。但長期暴露在外仍需注意維護。

②.  You can also choose steel open or closed bridge frames that have been hot-dip galvanized. Hot dip galvanizing can improve the corrosion resistance of cable trays. However, long-term exposure still requires attention to maintenance.

③. 如果采用熱浸鋅鋼質(zhì)橋架,可加裝蓋板改善防塵防雨效果。

③.  If hot-dip galvanized steel cable trays are used, cover plates can be installed to improve dust and rain resistance.

④. 大跨距情況下,優(yōu)先選用復(fù)合型橋架或鋼質(zhì)行架。

④.  In the case of large spans, composite cable trays or steel frames are preferred.
