防火桥架适用于敷设10KV以下的电力电缆,以及控制电缆、照明布线等室内外架空电缆沟、隧道。下面济南电缆桥架厂家分析防火桥架的使用基础情况。
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.
防火桥架主要由玻璃纤维增强材料和无机粘合剂制成的防火板、金属骨架制成的防火板和其他防火基材组成,外层涂有防火涂料。防火桥遇到火后不会燃烧,进而阻挡火势蔓延。该防火桥具有优异的防火阻燃效果,还具有耐火、耐油、耐腐蚀、无毒、所有设备方便等特点。
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.
防火桥架为钢制,内有双层防火盖板和无机防火槽盒。隔热层的均匀厚度为25毫米。双层盖板用于通风散热,内部喷涂防火涂料。当防火桥架遇到火灾时,油漆会膨胀,堵塞散热孔,保护槽盒内的电缆。无机防火槽盒的防火功能已经过国家防火检测中心60分钟测试,电缆质量过关。支架结构好,能有效固定无机防火槽盒。
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.
防火桥架内电缆敷设顺直时,应在电缆上端每隔1.5m距离固定在桥架支架上;水平敷设时,应固定在电缆的头、尾、转弯处和每隔3~5m的距离处。
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.

一般来说大量的电缆可以用直弯板和直齿条拉下,少量的电缆可以用导板或导管拉下,可以注明拉下的方法。防火桥架应高出地面2.2m以上,桥架顶部距天花板或其他障碍物不小于0.3m,桥架宽度不小于0.1m,桥架内截面填充率不超过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%.
防火桥架跨越电气设备时,两者净距不小于0.5m,两组防火桥架平行敷设在同一高度时,其净距不小于0.6m,大跨度沟槽从外部进入建筑物时,桥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.
有关于防火桥架的使用基础情况这个问题的相关解答就到这里了,您对此有什么看法都可以来我们网站http://www.sddlqj.cn交流分享,当然要记得好好维护桥架哦。
This is the end of the question about the basic use of fireproof cable tray. You can come to our website if you have any opinion http://www.sddlqj.cn Communicate and share. Of course, remember to maintain the cable tray.
