It brings you the fire protection problem of cable tray and the corresponding solutions. The combustible cable sheath may catch fire, so the cable fire will spread along the cable reel in the structure. This can be easily prevented by using flame retardant cable sheaths or by applying fire retardant coatings to installed cables. Thick coating or long fire damper may need to adjust the current rating of the cable, because this fire protection measure may reduce the heat dissipation of the installed cable.

定期清理房屋對(duì)很重要，因?yàn)殡娎|盤通常安裝在難以觸及的地方。如果不對(duì)托盤進(jìn)行例行檢查并保持清潔，可燃的灰塵和雜物可能會(huì)累積起來(lái)。

Regular house cleaning is important for safety because cable trays are usually installed in inaccessible places. If the tray is not routinely inspected and kept clean, combustible dust and debris may accumulate.

塑料和玻璃纖維增強(qiáng)塑料電纜橋架是可燃的;通過(guò)使用阻燃劑或防火材料可以減輕這種影響。

Plastic and glass fiber reinforced plastic cable trays are combustible; This effect can be mitigated by the use of flame retardants or fireproof materials.

鐵質(zhì)電纜橋架會(huì)隨著意外火災(zāi)的熱量增加而膨脹。德國(guó)Otto-Graf-Institut測(cè)試報(bào)告III.1-80999/Tei/tei證明了這一點(diǎn)，1984年10月23日的"關(guān)于在火災(zāi)測(cè)試中作用于電纜穿透式防火系統(tǒng)的機(jī)械力的補(bǔ)充測(cè)試"，使"軟"防火裝置，如那些由纖維絕緣材料和橡膠涂層制成的防火裝置移位。

The iron cable tray will expand as the heat of the accidental fire increases. The Otto Graf Institut test report iii.1-80999/tei/tei of Germany proves this point. The "supplementary test on mechanical force acting on cable penetrating fire protection system in fire test" of October 23, 1984 displaces "soft" fire protection devices, such as those made of fiber insulation and rubber coating.

這也適用于任何硅酮泡沫密封，但通過(guò)使用具有足夠壓縮強(qiáng)度和厚度的防火砂漿，可以很容易地補(bǔ)救，如上所示。此外，一些建筑法規(guī)規(guī)定，電纜盤等滲透物的安裝方式應(yīng)避免其對(duì)防火墻的坍塌產(chǎn)生影響。

This is also applicable to any silicone foam seal, but it can be easily remedied by using fireproof mortar with sufficient compression strength and thickness, as shown above. In addition, some building regulations stipulate that the installation of penetrations such as cable trays should avoid their impact on the collapse of the firewall.
