防火电缆桥架的种类及作用

     云南防火电缆桥架分防火漆和防火板电缆桥架两种。云南防火漆桥架为涂料有涂层薄、耐火极限高、粘接力强的特点。表面有磨砂感，一般运用在消防设备配电线路中，包括消防控制室、消防水泵、消防电梯、防排烟风机和火灾自动报警系统，除火灾自动报警系统外其他配电线路可采用耐火电缆。

      云南防火板桥架是在防火漆桥架基础上，内加防火板材，起到保护电缆电线的作用，相对于防火漆桥架而言，防火板桥架耐火性更好，但价格也更贵，在地下车库中要求耐火时间大于1h。适用于10KV以下电力电缆，以及控制电缆、照明配线等室内室外架空电缆沟、隧道的敷设。主要由玻璃纤维增强材料和无机黏合剂复合的防火板与金属骨架复合以及其他的防火基材组成。外层加防火涂料，遇火后不会燃烧，从而阻隔火势蔓延，具有极其良好的防火阻火效果，又具有耐火、耐油、耐腐蚀、无毒、无污染，整体安装方便，结构合理，使用寿命长，并且美观，电缆安装在电缆桥架中，环境整洁，清扫方便。

Yunnan fireproof cable tray is divided into two kinds of fireproof paint and fireproof board cable tray. Yunnan fireproof paint bridge has the characteristics of thin coating, high fire resistance limit and strong adhesion. The surface is frosted and generally used in the distribution lines of fire equipment, including fire control room, fire pump, fire elevator, smoke exhaust fan and automatic fire alarm system. In addition to the automatic fire alarm system, other distribution lines can use fire-resistant cables.

Yunnan fireproof board bridge is on the basis of fireproof paint bridge, add fireproof board, play the role of protecting cables and wires, relative to fireproof paint bridge, fireproof board bridge has better fire resistance, but the price is also more expensive, in the underground garage fire resistance time is more than 1h. It is suitable for laying power cables below 10KV, control cables, lighting wiring and other indoor and outdoor overhead cable trench and tunnel. It is mainly composed of glass fiber reinforced materials and inorganic adhesive composite fire-proof board and metal skeleton composite and other fire-proof base materials. Outer add fire-retardant coating, encounter after the fire will not burn, so as to cut off the fire spreading, has the extremely good fire flame retardant effect, but also has refractory, oil resistance, corrosion resistance, non-toxic, non-polluting, the overall installation is convenient, reasonable structure, long service life, and beautiful, the cable is installed in the cable tray, the environment clean and tidy, clean and convenient.
