电缆桥架和钢制桥架有什么区别？

What is the difference between cable tray and steel tray?

在相同规格下，阻燃型电缆桥架比钢制电缆桥架贵2.2倍，使用寿命是钢制电缆桥架的5倍以上，重量比钢制电缆桥架重30%。防火型电缆桥架比钢制电缆桥架稍贵，使用寿命是钢制电缆桥架的3倍以上，重量与钢制电缆桥架基本相同。

Under the same specification, flame retardant cable tray is 2.2 times more expensive than steel cable tray, its service life is more than 5 times that of steel cable tray, and its weight is 30% heavier than steel cable tray. The fireproof cable tray is slightly more expensive than the steel cable tray. Its service life is more than 3 times that of the steel cable tray, and its weight is basically the same as that of the steel cable tray.

电缆桥架类型型号有哪些？

What are the types and models of cable trays?

山东电缆桥架类型型号主要分为：槽式、梯式、托盘式等，具体比如：

Shandong cable tray types and models are mainly divided into: trough type, ladder type, tray type, etc., for example:

槽式电缆桥架：槽式电缆桥架是一种全封闭型的电缆桥架。适用于敷设计算机电缆、通信电缆、热电偶电缆及其他高灵敏系统的控制电缆等。它对控制电缆的屏蔽干扰和重腐蚀环境中电缆的防护都有较好的效果。

Trough type cable tray: the trough type cable tray is a fully enclosed cable tray. It is suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has good effect on shielding interference of control cable and cable protection in heavy corrosive environment.

梯式电缆桥架：外型像梯子形状，中间焊有横杆加固支撑使得重量轻、成本低、承受能力极强、透气性好，一般直径比较大的电缆和高、低动力电缆的敷设都会使用到。

Ladder type cable tray: it is shaped like a ladder, and a cross bar is welded in the middle for reinforcement and support, which makes it light in weight, low in cost, strong in bearing capacity and good in air permeability. It is generally used for the laying of cables with large diameter and high and low power cables.

托盘式电缆桥架：托盘式桥架是半密封型，它跟镀锌槽式桥架的样子非常相似，它具有重量轻、载荷大、造型美观、结构简单、安装方便等优点。

Tray type cable tray: tray type cable tray is a semi sealed type, which is very similar to the galvanized trough type cable tray. It has the advantages of light weight, large load, beautiful appearance, simple structure and convenient installation.

电缆桥架工程设计需要注意什么？

What should be paid attention to in cable tray engineering design?

在工程设计文件中通常笼统地将电缆桥架称呼为“桥架”，并未指出具体的结构特征，不同类型、不同制作材料的电缆桥架价格相差较大，且结构类型的混乱会带来工作现场散热、机械防护方面的问题。

In the engineering design documents, the cable tray is generally referred to as "tray", and the specific structural characteristics are not pointed out. The prices of cable trays of different types and materials vary greatly, and the confusion of structural types will bring problems in heat dissipation and mechanical protection at the work site.

故在设计阶段应要求设计人员根据工程环境特征和技术要求，合理选择电缆桥架的结构特征，并在平面图的型号标注和材料表中进行清晰地表达。电缆桥架的材质是电缆桥架工程设计常见的另外一个问题。

Therefore, in the design stage, the designer shall be required to reasonably select the structural features of the cable tray according to the environmental characteristics and technical requirements of the project, and clearly express them in the model annotation and material list of the plan. The material of cable tray is another common problem in cable tray engineering design.

按照材料划分，电缆桥架主要有钢制、玻璃钢和铝合金几种。玻璃钢电缆桥架的特点是质量轻，比重仅为碳钢的1/4；耐水性和耐腐蚀性好，适合化工厂。不易燃烧，难燃型玻璃钢电缆桥架的氧指数≥32。使用寿命长，一般设计寿命为20年，但价格是钢制电缆桥架的3倍。

According to the classification of materials, cable trays mainly include steel, FRP and aluminum alloy. 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. It is not easy to burn, and the oxygen index of fire-resistant FRP cable tray is ≥ 32. The service life is long. The general design life is 20 years, but the price is 3 times that of steel cable tray.

弱电电缆与其它低电压电缆合用桥架时应注意什么？

What should be paid attention to when the weak current cable and other low voltage cables share the bridge?

山东电缆桥架厂家认为，弱电电缆与其它低电压电缆合用桥架时,应严格执行选择具有外屏蔽层的弱电系统的弱电电缆,避免相互间的干扰。比如电缆桥架由室外进入建筑物内时,桥架向外的坡度不得小于1/100。

Shandong cable tray manufacturer believes that when the weak current cable and other low-voltage cables share the tray, the weak current cable of the weak current system with external shielding layer shall be strictly selected to avoid mutual interference. For example, when the cable tray enters the building from the outside, the outward slope of the tray shall not be less than 1/100.
