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.

防火電纜橋架的外殼由鋼制成，并配有雙層防火罩和無機防火箱。絕緣層的平均厚度設定為25mm，雙層蓋板用于通風散熱，防火涂層噴涂在內部。當防火電纜橋架與火災接觸時，涂料會膨脹，堵塞散熱孔，并保護水箱中的電纜。無機防火箱的防火性能經固定式消防試驗檢測60分鐘。

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.

電纜沒有損壞，支架結構良好，無機防火箱可以有效固定，是您不容錯過的不錯選擇。防火電纜托盤具有良好的防火性能和廣泛的應用。那么這種防火電纜的一般材料是什么？電纜橋架制造商將為您分析秘密。

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.

防火電纜托盤表面有啞光感。除火災自動報警系統外，一般用于各種消防配電線路，包括消防控制室，消防泵，消防電梯，排煙風機和自動火災報警系統。可以在生產線上使用防火電纜而無需防火橋。防火橋在地下車庫中需要超過1小時的耐火時間。

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.

需要對橋梁進行防火的部分可以添加到帶有耐火材料或阻燃板和網狀材料的托盤或梯架上，形成封閉或半封閉結構，并且橋梁表面按照CECS24涂漆;90“鋼結構防火涂料應用技術”本規范防火涂料的整體耐火性應符合有關標準和標準。優良的功能贏得了客戶的信賴，逐漸取代了舊橋。

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，電纜橋架具有較高的機械強度，具有金屬橋梁的剛性和玻璃鋼橋的韌性，耐腐蝕性好，抗老化性能好，外形美觀，安裝方便，使用壽命長。

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.
