Cable tray is the full name of rigid structure system, which has closely supported cable. The cable is composed of straight part of tray or ladder, bending part, supporting arm (arm bracket), hanger, etc. Today we will learn about the general materials of fireproof cable tray.

防火电缆桥架的外壳由钢制成，并配有双层防火罩和无机防火箱。绝缘层的平均厚度设定为25mm，双层盖板用于通风散热，防火涂层喷涂在内部。当防火电缆桥架与火灾接触时，涂料会膨胀，堵塞散热孔，并保护水箱中的电缆。无机防火箱的防火性能经固定式消防试验检测60分钟。

The shell of the fireproof cable tray is made of steel and equipped with double-layer fireproof cover and inorganic fireproof box. The average thickness of the insulation layer is set at 25 mm, the double-layer cover plate is used for ventilation and heat dissipation, and the fireproof coating is sprayed inside. When the fireproof cable tray is in contact with the fire, the coating will expand, block the heat dissipation hole, and protect the cables in the water tank. The fireproof performance of the inorganic fireproof box has been tested by the national fixed fire test center for 60 minutes.

电缆没有损坏，支架结构良好，无机防火箱可以有效固定，是您不容错过的不错选择。防火电缆托盘具有良好的防火性能和广泛的应用。那么这种防火电缆的一般材料是什么？电缆桥架制造商将为您分析秘密。

The cable is not damaged, the bracket structure is good, and the inorganic fireproof box can be effectively fixed, which is a good choice for you. Fireproof cable tray has good fireproof performance and wide application. So what is the general material of this kind of fireproof cable? The cable tray manufacturer will analyze the secret for you.

防火电缆托盘表面有哑光感。除火灾自动报警系统外，一般用于各种消防配电线路，包括消防控制室，消防泵，消防电梯，排烟风机和自动火灾报警系统。可以在生产线上使用防火电缆而无需防火桥。防火桥在地下车库中需要超过1小时的耐火时间。

The surface of fireproof cable tray has matte feeling. In addition to the automatic fire alarm system, it is generally used for various fire distribution lines, including fire control room, fire pump, fire elevator, smoke exhaust fan and automatic fire alarm system. Fire resistant cable can be used in production line without fire bridge. Fire bridges need more than one hour of fire resistance time in underground garages.

需要对桥梁进行防火的部分可以添加到带有耐火材料或阻燃板和网状材料的托盘或梯架上，形成封闭或半封闭结构，并且桥梁表面按照CECS24涂漆;90“钢结构防火涂料应用技术”本规范防火涂料的整体耐火性应符合有关标准和标准。优良的功能赢得了客户的信赖，逐渐取代了旧桥。

The part of the bridge that needs to be fireproof can be added to the tray or ladder with refractory or flame retardant plate and reticulated material to form a closed or semi closed structure, and the bridge surface shall be painted according to cecs24; 90 "application technology of fire retardant coating for steel structure" the overall fire resistance of fire retardant coating in this specification shall meet the relevant national standards and standards. Excellent function has won the trust of customers and gradually replaced the old bridge.

此外，电缆桥架具有较高的机械强度，具有金属桥梁的刚性和玻璃钢桥的韧性，耐腐蚀性好，抗老化性能好，外形美观，安装方便，使用寿命长。

In addition, the cable tray has high mechanical strength, rigidity of metal bridge, toughness of glass steel bridge, good corrosion resistance, good aging resistance, beautiful appearance, convenient installation and long service life.
