Many places in our life will use electricity, so there are many cable trays. It is learned that in the installation and construction of cable tray, there are often some cases that need to install protective covers on site, but what is the specific situation? Next is the reason why Jinan cable tray is installed with protective cover. How does the shielding layer of cable tray protect the cable tray? Let's have a look!

一、济南电缆桥架为什么要加装保护罩?

1、 Why should Jinan cable tray be equipped with protective cover?

(1)如果电缆桥架安装在室外，保护盖需要安装在地板上或每层地板上。

(1) If the cable tray is installed outdoors, the protective cover needs to be installed on the floor or each floor.

(2)如果您处于易受机械损坏或灰尘影响的环境中，或者您有特殊要求，您需要安装防护罩

(2) If you are in an environment vulnerable to mechanical damage or dust, or you have special requirements, you need to install a protective cover

(3)电缆桥架安装在铁板下或类似的打孔装置下，桥架上部必 须装有防护罩;如果上桥的宽度小于下桥的宽度，需要配备防护罩;如果电缆桥架垂直安装，需要在离地面不超过两米的位置安装保护罩。

(3) The cable tray is installed under the iron plate or similar drilling device, and the upper part of the tray must be equipped with a protective cover; If the width of the upper bridge is less than that of the lower bridge, the protective cover shall be provided; If the cable tray is installed vertically, the protective cover shall be installed no more than two meters above the ground.

电缆桥架：智能建筑的弱电系统通常由BA(楼宇自动化)、OA(办公自动化)、CA(通信自动化)等信息监控和通信设施对应的各种系统组成。电缆桥架分为线槽、托盘和梯子结构，由支架、托架和安装附件组成。选择桥梁时，要注意其构件是否满足系列化、通用化、标准化的要求。建筑内部的桥梁可以独 立架设，也可以附着在各种建筑和管架上，应具有结构简单、外形美观、配置灵活、维护方便的特点。所有部件都应镀锌，并安装在室外的桥梁上。如果安装在海岸附近或腐蚀区域附近，材料需要耐腐蚀和防潮。

Cable bridge: the weak current system of intelligent building is usually composed of BA (building automation), OA (office automation), Ca (Communication Automation) and other systems corresponding to information monitoring and communication facilities. The cable tray is divided into trunking, tray and ladder structure, which is composed of bracket, bracket and installation accessories. When choosing a bridge, we should pay attention to whether its components meet the requirements of serialization, generalization and standardization. The bridge inside the building can be erected independently or attached to various buildings and pipe supports. It should have the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All components shall be galvanized and installed on outdoor bridges. If installed near the coast or near corrosive areas, the material needs to be resistant to corrosion and moisture.

电缆桥架罩是一种用于电力或通信电缆布线工程电缆桥架的罩，由钢板压制而成。电缆桥架上的盖子两面不平，两个面的高度差小于8毫米，凸凹面连续排列，每个凸凹单元的两头同向弯曲，凸凹面的高度差大于两倍。它的主要优点是降低成本。

Cable tray cover is a kind of cover used for cable tray of power or communication cable routing engineering, which is made of steel plate. The two sides of the cover on the cable tray are uneven, the height difference between the two surfaces is less than 8 mm, the convex and concave surfaces are arranged continuously, the two ends of each convex and concave unit are bent in the same direction, and the height difference between the convex and concave surfaces is more than twice. Its main advantage is cost reduction.
