The use of cable tray we will see in some laying of cable field occasions, mainly play a role in cable maintenance, some people will worry that if the cable is damaged, the cable tray is not also on fire, in fact, the bridge has fire performance. So what is the fire standard of shandong cable bridge?

　　防火電纜橋架主要依據(jù)防火電纜的標(biāo)準(zhǔn)。防火層厚度要求大于等于1mm，耐火30分鐘。這是防火電纜防火涂料的標(biāo)準(zhǔn)。防火材料為鋼材，防火電纜外層也包覆防火材料。

　　Fireproof cable tray is mainly based on the national standard of fireproof cable. The thickness of the fire protection layer must be greater than or equal to 1mm, and the fire resistance should be 30 minutes. This is the standard of fire retardant coating for fire retardant cables. The fireproof material is steel, and the fireproof cable is also covered with fireproof material.

　　盡量選擇鋼制或不燃阻燃材料制成的電纜橋架。防火電纜橋架采用鋼殼，雙層防火罩，配無(wú)機(jī)防火箱。保溫層厚度均勻?yàn)?5mm，雙層罩蓋通風(fēng)散熱，內(nèi)部噴涂防火漆。防火電纜橋架在發(fā)生火災(zāi)時(shí)會(huì)膨脹，在60分鐘的防火測(cè)試期間，電纜沒有損壞，支撐結(jié)構(gòu)很好。

　　Try to choose the cable tray made of steel or non-combustible flame retardant materials. Fireproof cable tray adopts steel shell, double layer fireproof cover and inorganic fireproof box. The thickness of insulation layer is 25mm evenly, the double cover is ventilated and heat dissipated, and the interior is sprayed with fireproof paint. The fireproof cable tray expands in the event of a fire. During the 60 minute fire test, the cable was not damaged and the supporting structure was in good condition.

　　防火電纜的高標(biāo)準(zhǔn)是英國(guó)的bs6387標(biāo)準(zhǔn)。普通電纜敷設(shè)防火橋時(shí)，需要注意以下幾點(diǎn)：

　　The highest standard for fireproof cables is the British standard bs6387. When laying fire Bridges with ordinary cables, pay attention to the following points:

　　外層涂有防火涂料?；馂?zāi)發(fā)生后，防火橋不會(huì)燃燒，從而防止火勢(shì)蔓延。具有優(yōu)良的防火阻燃效果，具有防火、耐油、耐腐蝕、無(wú)毒、無(wú)污染的特點(diǎn)。事實(shí)上，這座橋本身并沒有著火。只是著火了。因此，現(xiàn)在許多項(xiàng)目都使用耐火電纜來(lái)節(jié)省電纜橋架和維護(hù)成本。

　　The outer layer is coated with fire retardant paint. After a fire, the fireproof bridge does not burn, thus preventing the fire from spreading. With excellent fire retardant effect, with fire, oil resistance, corrosion resistance, non-toxic, pollution-free characteristics. In fact, the bridge itself was not on fire. It's just a fire. Therefore, fire-resistant cables are now used in many projects to save cable trays and maintenance costs.

　　防火橋是在普通橋梁表面噴涂一層防火涂料，起到防火、阻燃的作用。防火涂料的防火阻燃原理，防火橋的防護(hù)厚度按JB/T10216-2000《電控配電》中“電纜橋”表10的要求，涂層大于12μm，熱浸涂層大于65μm，噴涂層大于50μm，耐火性大于500μm，可用測(cè)厚儀測(cè)量。

　　Fireproof bridge is sprayed on the surface of ordinary bridge with a layer of fireproof coating, which plays the role of fire prevention and flame retardant. Fire retardant coating fire retardant principle, fire bridge protection thickness according to JB/T10216-2000 "electric control distribution" "cable bridge" table 10 requirements, coating is greater than 12μm, hot dip coating is greater than 65μm, spraying layer is greater than 50μm, fire resistance is greater than 500μm, can be measured by thickness meter.

　　另外電纜橋架的防火能力植根于其材料和制造過(guò)程，不同材料和不同制造工藝的防水能力有所不同。因此，山東電纜橋架廠家的防火電纜橋架的標(biāo)準(zhǔn)化設(shè)置就顯得尤為重要，這可以使防火電纜橋架更加統(tǒng)一可靠。

　　In addition, the fireproof ability of cable tray is rooted in its material and manufacturing process, and the waterproof ability of different materials and different manufacturing processes is different. Therefore, the standardized setting of the fireproof cable tray of Shandong cable tray manufacturer is particularly important, which can make the fireproof cable tray more unified and reliable.
