The fire-proof ability of cable bridge is based on its material and manufacturing technology. There are deviations in the water-proof ability of different materials and different manufacturing processes. So the standardization of fire-proof cable bridge is particularly important. It can make the fire-proof cable bridge more uniform and reliable.

防火電纜橋架分為，內阻燃型、外阻燃型和全阻燃型，更重要的部分即是防火板，防火板選用硅質資料和鈣質資料為主要原料，與必定比例的纖維資料、輕質骨料、黏合劑和化學添加劑混合，經的蒸壓技能制成。加工成型后斷面形狀均勻、無曲折、擰曲、裂縫、邊緣等缺點，但無論是哪一類防火橋架，都必須符合電纜橋架標準 。

Fire-proof cable bridge is divided into internal flame-retardant type, external flame-retardant type and full flame-retardant type. The most important part is the fire-proof board. The fire-proof board is made of silica material and calcium material as main raw materials, mixed with certain proportion of fiber material, lightweight aggregate, adhesives and chemical additives, and made by leading autoclaving skills. After processing and forming, the cross-section shape is uniform, without flexure, twist, crack, edge and other shortcomings, but no matter what kind of fire-proof bridge, it must meet the national standards of cable bridge.

防火涂料是一種鋼結構維護商品。它精選高分子合成樹脂為成膜物質，加以阻燃劑、發泡劑、炭化劑及高溫耐火資料制作而成的。它在高溫條件下，涂層發作接連發泡膨脹效應，構成柔韌的海綿狀的炭化隔熱層，使承載的鋼結構不會因高溫烈焰的效果而急劇軟化變形，強度不會急劇下降。表面防火涂料層噴涂要求均勻、光潔、無明顯色差。

Fire retardant coating is a kind of high efficiency steel structure maintenance commodity. It is made of high polymer synthetic resin as film forming material, flame retardant, foaming agent, carbonizing agent and high temperature refractory material. Under high temperature conditions, the coatings have successive foaming and expansion effects, forming a flexible spongy carbonized insulation layer, so that the bearing steel structure will not be sharply softened and deformed due to the effect of high temperature flame, and the strength will not sharply decrease. The spraying of surface fire retardant coatings requires uniformity, smoothness and no obvious color difference.

如今防火電纜橋架已被應用到敷設電纜的各個領域，對電纜的維護起到極好的作用，在對電纜的阻燃、防火方面做到了非常好的保護，是其他不銹鋼橋架無可比擬的。

Nowadays, fire-proof cable bridge has been applied in all fields of laying cables. It plays an excellent role in the maintenance of cables. It has achieved very good protection in fire-retardant and fire-proof aspects of cables, which is incomparable with other stainless steel bridge frames.

Fire-proof cable bridge

1、防火電纜橋架重要依據國度對防火電纜標準進行鍛煉標準。防火期厚度要求大于等于1mm，耐火必需年夜于三十分鐘，這是一般的防火電纜防火漆結果的標準，防火的根本是鋼材，而且防火電纜外層還圖有一層防火材料。

1. Fire-proof cable bridge is based on the national standard for fire-proof cable exercise. The thickness requirement of fire protection period is greater than or equal to 1 mm, and the fire resistance must be greater than 30 minutes. This is the standard of the result of fire protection paint for general fire-proof cables. The basic fire prevention is steel, and the outer layer of fire-proof cables is also shown with a layer of fire-proof material.

2、盡量選擇鋼制或不燃、阻燃材料的電纜橋架。防火電纜橋架采納鋼制外殼，雙層防火蓋板,內裝無機防火槽盒 .隔熱層均勻厚度為25mm,雙層蓋板通風散熱,內噴防火涂料,防火電纜橋架遇火時涂料脹大,在60分鐘耐火試驗,電纜無損傷.支撐的構造性好。

2. Choose steel or non-flammable or flame-retardant cable bridge as far as possible. Fire-proof cable bridge frame adopts steel shell, double-layer fire-proof cover board and inorganic fire-proof tank box. The uniform thickness of heat insulation layer is 25 mm. The double-layer cover board ventilates and dissipates heat, sprays fire-proof coating inside. When fire-proof cable bridge frame is in fire, the coating expands. After 60 minutes fire-proof test, the cable is not damaged. The structure of the support is good.
