01 电缆桥架简介

　　01 Introduction to Cable Tray

　　电缆桥架作为布线工程的一个配套项目，目前尚无专门的规范指导，每个生产厂家的规格程式缺乏通用性，因此，设计选型过程应根据弱电各个系统缆线的类型、数量，合理选定适用的桥架。可以独立架设,也可以敷设在各种建(构)筑物和管廊支架上，体现结构简单、造型美观、配置灵活和维修方便等特点，全部零件均需进行镀锌处理，安装在建筑物外露天的桥架，如果是在邻近海边或属于腐蚀区，则材质必须具有防腐、耐潮气、附着力好，耐冲击强度高的物性特点。

　　As a supporting project of wiring engineering, there is currently no specialized specification guidance for cable trays, and the specifications and programs of each manufacturer lack universality. Therefore, the design and selection process should be based on the type and quantity of cables in various weak current systems, and the appropriate cable tray should be selected reasonably. It can be independently erected or laid on various buildings and pipe gallery supports, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration, and easy maintenance. All parts need to be galvanized and installed on the bridge outside the building. If it is near the seaside or in a corrosive area, the material must have physical properties such as anti-corrosion, moisture resistance, good adhesion, and high impact strength.

　　电缆桥架是由托盘或梯架的直线段、弯通、组件以及托臂（臂式支架）、吊架等构成具有密接支撑电缆的刚性结构系统之全称。工具/原料：是设计选型、保障的权威技术参考；电缆原材料、电缆附件、电缆设备、电缆桥架、电缆盘具、施工工具、线缆连接器等。

　　Cable tray is a rigid structural system consisting of straight sections, bends, components, as well as support arms (arm brackets), hangers, etc. of trays or ladders that tightly support cables. Tools/raw materials: authoritative technical references for design selection and transaction assurance; Cable raw materials, cable accessories, cable equipment, cable trays, cable reels, construction tools, cable connectors, etc.

　　02 电缆桥架的分类

　　02 Classification of Cable Trays

　　电缆桥架是一款为保护电缆而衍生的产品，是电缆的保护壳，防止电缆受到外界因素的损坏。主要由支架、托臂和安装附件组成，桥架主要类型可以分为梯式桥架、无孔托盘式桥架（槽式桥架）、有孔托盘式桥架（托盘式电缆桥架）、大跨距电缆桥架等。

　　Cable tray is a product derived from protecting cables, serving as a protective shell for cables to prevent damage from external factors. It mainly consists of brackets, support arms, and installation accessories. The main types of cable trays can be divided into ladder type cable trays, non perforated tray type cable trays (trough type cable trays), perforated tray type cable trays (tray type cable trays), large-span cable trays, etc.

　　▲ 槽式电缆桥架槽式电缆桥架是一种全封闭型的电缆桥架。用整张钢板弯制而成的槽式部件，其概念上与盘架的区别是高、宽比不同，盘架浅而宽，槽式电缆桥架具有一定的深度和封闭性。

　　▲ Trough type cable tray Trough type cable tray is a fully enclosed cable tray. The difference between a trough type component made by bending a whole steel plate and a tray is the height to width ratio. The tray is shallow and wide, while the trough type cable tray has a certain depth and enclosure.

　　▲ 托盘式电缆桥架托盘式桥架是半密封型，跟镀锌槽式桥架的样子非常相似。托盘式电缆桥架其表面处理可根据用户需要分为镀锌、静电喷塑和热镀锌三种，在重腐蚀环境中可作特殊防腐处理

　　The tray type cable tray is a semi sealed type, which looks very similar to the galvanized trough type cable tray. The surface treatment of tray type cable trays can be divided into three types according to user needs: galvanizing, electrostatic spraying, and hot-dip galvanizing. Special anti-corrosion treatment can be carried out in heavily corrosive environments

　　▲ 梯式电缆桥架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；CQ1-T型梯级式电缆桥架根据国内外有关资料改进设计的。

　　▲ Ladder type cable tray The ladder type cable tray is shaped like a ladder, with a horizontal bar welded in the middle to reinforce and support it, making it lightweight, low-cost, highly load-bearing, and breathable; The CQ1-T stepped cable tray has been improved and designed based on relevant domestic and foreign data.

　　▲ 大跨距电缆桥架大跨距电缆桥架一般是由拉挤玻璃钢型材组装而成，适用于电力电缆、控制电缆、照明电缆及配件等。

　　▲ Large span cable trays are generally assembled from extruded fiberglass profiles and are suitable for power cables, control cables, lighting cables, and accessories.

　　03 电缆桥架的材质分类

　　03 Classification of Materials for Cable Trays

　　电缆桥架按材质可分类：镀锌桥架、不锈钢桥架、铝合金桥架、防火桥架、喷塑桥架、热镀锌桥架。

　　Cable trays can be classified by material: galvanized trays, stainless steel trays, aluminum alloy trays, fireproof trays, spray painted trays, and hot-dip galvanized trays.
