如果您在有防火要求的路段购买电缆桥架，可以在电缆梯的桥架上添加防火或阻燃的板、网等材料。形成密闭或半密闭结构，采取在桥梁及其支吊架表面涂刷防火涂料等措施，达到防火要求。

If you buy cable trays in sections with fire protection requirements, you can add fireproof or flame-retardant plates, nets and other materials to the cable ladder trays. Form a closed or semi closed structure, and take measures such as painting fireproof paint on the surface of the bridge and its supports and hangers to meet the fire protection requirements.

如果要在腐蚀环境中使用，应采用耐腐蚀的刚性材料制成或经过防腐处理。防腐处理方法应符合工程环境要求。环境和耐久性要求。如果有电缆线或油、腐蚀性液体、易燃粉尘等环境要求需要屏蔽电磁干扰。

If it is to be used in corrosive environment, it shall be made of corrosion-resistant rigid materials or treated with corrosion protection. The anti-corrosion treatment method shall meet the environmental requirements of the project. Environmental and durability requirements. If there are environmental requirements such as cable or oil, corrosive liquid, flammable dust, etc., electromagnetic interference shall be shielded.

在工程设计文件中，电缆桥架一般简称为“桥架”，并没有指出具体的结构特点、不同类型和材料的电缆桥架。差异大，结构类型的混乱会带来工作场所的散热和机械保护方面的问题。因此，在设计阶段，应要求设计者应根据特点和技术要求，合理选择电缆桥架的结构特点，并在方案的型号标识和材料表中明确表示。

In the engineering design documents, the cable tray is generally referred to as "tray", and the specific structural characteristics, different types and materials of cable tray are not indicated. Large price differences and confusion of structural types will bring problems in heat dissipation and mechanical protection in the workplace. Therefore, in the design stage, the designer shall be required to reasonably select the structural characteristics of the cable tray according to the characteristics and technical requirements, and clearly indicate them in the model identification and material list of the scheme.

电缆桥架的材料是电缆桥架工程设计中的另一个常见问题。按材质分，电缆桥架主要由钢材、玻璃钢和铝材制成。玻璃钢电缆桥架的特点是重量轻，比重仅为碳钢的1/4；良好的耐水性和耐腐蚀性，适用于化工厂。不易燃、阻燃的玻璃钢电缆桥架支架氧指数≥32。使用寿命长，一般设计寿命为20年，但是钢制电缆桥架的3倍。施工的优点在于切割方便，组装灵活。

The material of cable tray is another common problem in cable tray engineering design. According to the material, the cable tray is mainly made of steel, FRP and aluminum. Fiberglass reinforced plastic cable tray is characterized by light weight, and its specific gravity is only 1/4 of that of carbon steel; Good water resistance and corrosion resistance, suitable for chemical plants. Oxygen index of non flammable and flame retardant FRP cable tray support ≥ 32. The service life is long. The general design life is 20 years, but the price is 3 times that of steel cable tray. The construction has the advantages of convenient cutting and flexible assembly.

对于爆炸性危险环境下的化工厂项目意义重大，一期工程紧张，因为在爆炸性危险环境下，项目的热装是不必要的。当化工厂必须停产时，经济效益就会受到影响。铝合金电缆桥架重量也很轻。由于铝和钢的比重不同（Al=2.7，Fe=7.86），以重星计算。经计算，铝与钢的比例约为1：3。铝制电缆桥架的尺寸和负载特性与钢制桥架基本相似。在成本方面，铝合金桥架的成本高于电镀锌钢桥架高出20%，使用寿命是钢桥架的5倍以上。

It is of great significance for the chemical plant project in explosive hazardous environment, and the phase I project is tense, because the hot charging of the project is unnecessary in explosive hazardous environment. When the chemical plant has to stop production, the economic benefit will be affected. The weight of aluminum alloy cable tray is also very light. Since the specific gravity of aluminum and steel is different (al=2.7, fe=7.86), it is calculated by heavy star. After calculation, the ratio of aluminum to steel is about 1:3. The size and load characteristics of aluminum cable tray are basically similar to those of steel cable tray. In terms of cost, the cost of aluminum alloy bridge is 20% higher than that of galvanized steel bridge, and its service life is more than 5 times that of steel bridge.

电缆桥架的种类很多，大多数电缆桥架由支架、支撑臂、安装附件等组成。零部件必须满足标准化、通用化、系列化的要求，以方便日后的维护和维修。此外，还要确定电缆桥架的形状和结构是否美观，是否合理，配置是否灵活应考虑。由于电缆桥架一般安装在室外，因此周围环境的特点也是重要的因素。

There are many kinds of cable trays, most of which are composed of brackets, support arms, installation accessories, etc. Parts must meet the requirements of standardization, generalization and serialization to facilitate future maintenance and repair. In addition, it is necessary to determine whether the shape and structure of the cable tray are beautiful, reasonable and flexible. Since cable trays are generally installed outdoors, the characteristics of the surrounding environment are also important factors.

这是为了电缆桥架的耐腐蚀性、耐湿性和附着力性能起着关重要的作用。总而言之，济南电缆桥架厂家建议您必须选择正确的电缆桥架购买才行。更多内容来网站www.sddlqj.cn关注咨询吧！

This is to play a crucial role in the corrosion resistance, humidity resistance and adhesion performance of cable tray. In a word, Jinan cable tray manufacturer suggests that you must choose the right cable tray to buy.
