防火橋架適用于敷設10KV以下的電力電纜，以及控制電纜、照明布線等室內外架空電纜溝、隧道。下面濟南電纜橋架廠家分析防火橋架的使用基礎情況。

Fireproof cable tray is applicable to laying power cables below 10KV, control cables, lighting wiring and other indoor and outdoor overhead cable trenches and tunnels. Next, the cable tray manufacturer in Jinan will analyze the use basis of fire resistant cable tray.

防火橋架主要由玻璃纖維增強材料和無機粘合劑制成的防火板、金屬骨架制成的防火板和其他防火基材組成，外層涂有防火涂料。防火橋遇到火后不會燃燒，進而阻擋火勢蔓延。該防火橋具有優異的防火阻燃效果，還具有耐火、耐油、耐腐蝕、無毒、所有設備方便等特點。

The fireproof bridge is mainly composed of fireproof board made of glass fiber reinforced material and inorganic adhesive, fireproof board made of metal skeleton and other fireproof substrates, and the outer layer is coated with fireproof coating. The fire bridge will not burn after encountering fire, thus preventing the spread of fire. The fireproof bridge has excellent fireproof and flame retardant effects, and is also characterized by fire resistance, oil resistance, corrosion resistance, non-toxic, and convenient equipment.

防火橋架為鋼制，內有雙層防火蓋板和無機防火槽盒。隔熱層的均勻厚度為25毫米。雙層蓋板用于通風散熱，內部噴涂防火涂料。當防火橋架遇到火災時，油漆會膨脹，堵塞散熱孔，保護槽盒內的電纜。無機防火槽盒的防火功能已經過國家防火檢測中心60分鐘測試，電纜質量過關。支架結構好，能有效固定無機防火槽盒。

The fireproof cable tray is made of steel, with double-layer fireproof cover plate and inorganic fireproof slot box inside. The uniform thickness of the insulation is 25 mm. The double-layer cover plate is used for ventilation and heat dissipation, and the interior is sprayed with fireproof paint. When the fireproof tray encounters a fire, the paint will expand, block the cooling hole, and protect the cable in the tray. The fireproof function of the inorganic fireproof tray has been tested by the National Fire Protection Testing Center for 60 minutes, and the cable quality is qualified. The support structure is good and can effectively fix the inorganic fireproof tank box.

防火橋架內電纜敷設順直時，應在電纜上端每隔1.5m距離固定在橋架支架上；水平敷設時，應固定在電纜的頭、尾、轉彎處和每隔3~5m的距離處。

When the cables in the fireproof tray are laid straight, they shall be fixed on the tray support at the upper end of the cable every 1.5m; When laying horizontally, it shall be fixed at the head, tail, turn and every 3~5m.

一般來說大量的電纜可以用直彎板和直齒條拉下，少量的電纜可以用導板或導管拉下，可以注明拉下的方法。防火橋架應高出地面2.2m以上，橋架頂部距天花板或其他障礙物不小于0.3m，橋架寬度不小于0.1m，橋架內截面填充率不超過50%。

Generally speaking, a large number of cables can be pulled down with straight bending plates and straight racks, while a small number of cables can be pulled down with guide plates or conduits, and the pulling method can be indicated. The fireproof cable tray shall be more than 2.2m above the ground, the distance from the top of the cable tray to the ceiling or other obstacles shall not be less than 0.3m, the cable tray width shall not be less than 0.1m, and the filling rate of the section in the cable tray shall not exceed 50%.

防火橋架跨越電氣設備時，兩者凈距不小于0.5m，兩組防火橋架平行敷設在同一高度時，其凈距不小于0.6m，大跨度溝槽從外部進入建筑物時，橋梁向外的坡度不得小于1/100。

When the fireproof cable tray crosses the electrical equipment, the clear distance between them shall not be less than 0.5m. When two groups of fireproof cable trays are laid at the same height in parallel, the clear distance shall not be less than 0.6m. When the large-span trench enters the building from the outside, the gradient of the bridge shall not be less than 1/100.
