防火槽式电缆桥架是由镀锌槽式桥架经过加工表面处理一层防火涂料生产而成，表面摸起来会有粗糙斜斜的感觉，当遇到火灾后不会燃烧，并且可以阻隔火势继续蔓延下去，起到一定的防火作用，并且采用了高颜料使得桥架上的防火涂料具有、无污染，耐火、耐水、耐油....的性能。一般用于敷设：电力电缆、通讯信号电缆...等等。

　　Fireproof trough cable tray is made of galvanized trough bridge after processing surface treatment production fireproof coating layer and a surface touch will have a rough slanting feeling, when the fire will not burn, and can block the further spread of the fire down, play a certain role of fire, and the use of high environmental protection paint makes fire the bridge on the coating has no toxicity, no pollution, fire resistance, water resistance, oil resistance. The performance... Generally used for laying: power cables, communication signals, cables, etc..

　　防火桥架是在普通桥架表面喷涂一层防火漆，以起到防火阻燃的作用!其实桥架本身并不会着火，着火的只可能是电缆，防火漆所起到的防火阻燃原理

　　The fireproof bridge is sprayed with a fireproof paint on the surface of the ordinary bridge frame, so as to play the role of fire prevention and flame retardance! In fact, the bridge itself does not fire, fire may only be cable, fire retardant fire retardant principle

　　热镀锌是使熔融金属与铁基体反应而产生合金层，从而使基体和镀层二者相结合。热镀锌具有镀层均匀，附着力强，使用寿命长等优点。

　　Hot galvanizing is to produce molten metal and iron matrix reaction and produce alloy layer, so that the substrate and coating two combination. Hot galvanizing has the advantages of uniform coating, strong adhesion, long service life and so on.

　　冷镀锌就是电镀锌，其本身的耐腐蚀性比热镀锌相差很多。也相对便宜一些。

　　Cold galvanizing is zinc plating, and its corrosion resistance is much different from that of galvanized iron. The price is relatively cheaper.

　　镀锌成品的区别：热镀锌外表没有冷镀锌细腻光亮，但锌层厚度方面热镀锌是冷镀锌的几十倍。防腐蚀性能也是电镀锌的几十倍。

　　The difference between galvanized products: hot galvanized surface is not cold galvanized, delicate and bright, but the thickness of zinc coating, hot galvanizing is cold galvanized dozens of times. Corrosion resistance is also tens of times zinc plating.

　　阻燃防火桥架适用于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。阻燃型桥架分为内阻燃型、外阻燃型及全阻燃型。

　　The flame retardant fireproof bridge is suitable for laying power cables, power cables, lighting wiring, indoor and outdoor aerial cable trench and tunnel laying under 10KV. Flame retardant bridge is divided into internal combustion, flame retardant, and flame retardant type.

　　内阻燃型是在槽式或托盘式电缆桥架和内表面涂覆阻燃材料或镶嵌阻燃板，常用于阻燃隔断，即当电缆着火时，由于阻燃段的作用，可限制着火电缆的延燃长度。

　　The internal resistance of combustion type is in the groove type or tray type cable tray and inner surface coated flame-retardant materials or embedded flame retardant board, commonly used in flame retardant partition, namely when the cable is on fire, because the fire retardant section, the length of delay can limit the fuel ignition cable.
