1、 What is a fireproof bridge

防火桥架是电缆桥架根据防火功能分出来的一种桥架类，一种是以具有耐火属性的璃纤维增强材料制作的玻璃钢桥架，一种是在普通桥架表面喷防火漆，使桥架具有耐火属性。

Fire resistant bridge is a kind of bridge classified according to the fire protection function of cable bridge. One is FRP Bridge made of glass fiber reinforced material with fire resistance property, and the other is to spray fire-resistant paint on the surface of ordinary bridge to make the bridge have fire resistance property.

防火桥架具有良好的防火阻火效果，此外还可以耐火、耐油、耐腐蚀、没有污染，十分受买家的亲睐。

Fireproof bridge has good fire prevention and fire resistance effect. In addition, it can be fire-resistant, oil-resistant, corrosion-resistant and pollution-free. It is very popular with buyers.

二、防火桥架有哪些标准？

2、 What are the national standards for fire-proof bridge?

防火桥架的标准：

National standard for fireproof bridge:

1、关于防火桥架防火等级可以根据《电控配电用电缆桥架》规定，防火桥架分为三个耐火等级，耐火30分钟代号N1，耐火45分钟代号N2，耐火60分钟代号N3。

1. As for the fire rating of fire-proof bridge, according to the regulations of cable bridge for electric power distribution, the fire-proof bridge is divided into three fire ratings, namely, 30 minute fire resistance code N1, 45 minute fire resistance code N2 and 60 minute fire resistance code N3.

2、防火桥架表面防火涂料应大于等于500μm。

2. The fireproof coating on the surface of fireproof bridge shall be greater than or equal to 500 μ m。

3、钢结构防火桥架应按照《钢结构防火涂料应用技术规范》规定相关技术生产。

3. The steel structure fireproof bridge shall be produced in accordance with the relevant technologies specified in the technical code for application of fire retardant coatings for steel structures.

三、防火桥架如何选择？

3、 How to select fireproof bridge?

挑选防火桥架一定要认证桥架生产厂家，技术精湛，有相关质量保证企业ISO9001，欧盟CE认证等相关资质。

The selection of fire-proof bridge must be certified as the bridge manufacturer, with exquisite technology, relevant national quality assurance enterprise ISO9001, EU CE certification and other relevant qualifications.

防火桥架和普通桥架的区别是什么？

What is the difference between fireproof bridge and ordinary bridge?

四、防火桥架和普通桥架区别的是什么？

4、 What is the difference between fireproof bridge and ordinary bridge?

防火桥架和普通桥架区别：用途

Difference between fireproof bridge and ordinary bridge: Purpose

1、防火桥架适用于低于10KV的电力电缆，和操控电缆、照明配线等室内室外架空电缆沟、地道的敷设。

1. The fireproof bridge is applicable to the laying of power cables lower than 10kV, indoor and outdoor overhead cable trenches and tunnels such as control cables and lighting wiring.

2、普通桥架主要应用在湿润、腐蚀性强环境下。

2. Ordinary bridge is mainly used in humid and corrosive environment.

防火桥架和普通桥架区别：生产技术

Difference between fireproof bridge and ordinary bridge: production technology

1、防火桥架主要由玻璃纤维增强材料、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

1. The fireproof bridge is mainly composed of glass fiber reinforced material, inorganic adhesive composite fireproof board, metal skeleton composite and other fireproof base materials, and the outer layer is added with fireproof coating

2、按照生产技术不一样，分为热镀锌和电镀锌(即冷镀锌）两种。两种的技术进程不一样，所以两者的能力也不一致：。热镀锌镀层较厚，抗腐蚀才能较强；冷镀锌镀锌层较热镀亮光，但较薄，抗锈蚀才能较弱。

2. According to different production technologies, it is divided into hot galvanizing and electro galvanizing (i.e. cold galvanizing). The technological processes of the two are different, so their capabilities are also inconsistent:. The hot-dip galvanized coating is thick and has strong corrosion resistance; The cold galvanized layer is brighter than the hot-dip coating, but it is thinner, and the corrosion resistance is weak.

通过上面的对防火桥架和普通桥架区别问题的阐述，相信大家也能明白防火桥架的优点，此外，防火桥架还具有安装便利，结构合理，使用寿命长，美观易清理等特点

Through the above description of the difference between fire-proof bridge and ordinary bridge, I believe you can also understand the advantages of fire-proof bridge. In addition, fire-proof bridge also has the characteristics of convenient installation, reasonable structure, long service life, beautiful and easy to clean
