槽式桥架是现代电气工程中应用为广泛的一种无孔托盘桥架，槽式桥架的桥架材质、桥架品种样式、桥架的规格、桥架表面防护都属于槽式桥架型号信息。槽式桥架标准长度一般为2米，当然也有3米、4米、6米的，弯曲半径有200mm、400mm、600mm等。更多详细内容 济南电缆桥架厂家认为您可以参考下面：

The trough-type cable tray is a kind of holeless cable tray which is widely used in modern electrical engineering. The material, type, specification and surface protection of the trough-type cable tray belong to the type information of the trough-type cable tray. The standard length of trough-type cable tray is generally 2 meters, of course, there are also 3 meters, 4 meters, 6 meters, and the bending radius is 200 mm, 400 mm, 600 mm, etc. Jinan cable bridge manufacturer thinks you can refer to the following for more details:

1、槽式桥架

1. Trough-type bridge

水平槽式桥架敷设的端部、进出接线箱的转角处、转弯处、穿越变形缝的两端、水平三通的三个端点、水平四通的四个端点，都应该增设支吊架。镀锌托盘或梯架两节进行槽式桥架敷设时，中间的连接片如果不用跨接线，则需要在其两端安装不少于2个带防松螺帽或防松垫圈的固定螺栓。

Supports and hangers shall be added at the ends of the horizontal trough-type cable tray, the corners of the junction box, the corners, the two ends of the deformation joint, the three ends of the horizontal tee, and the four ends of the horizontal cross. When two sections of the galvanized tray or ladder are laid on the trough-type bridge, if the jumper wire is not used for the connecting piece in the middle, it is necessary to install at least two fixing bolts with lock nuts or lock washers at both ends.

低压动力电缆适合采用梯级式、托盘式、组合式结构的槽式桥架，高压动力槽式桥架适合采用梯级式、托盘式结构的槽式桥架。槽式桥架敷设之前土建施工应当已经完成，竖井井道的封顶已完成，保证安装周边环境的整洁干净。槽式桥架敷设之前穿墙和跨楼层的孔洞位置要保证准确。

Low-voltage power cable is suitable for the use of ladder type, tray type and combined structure of trough-type bridge. High-voltage power trough-type bridge is suitable for the use of ladder type, tray type structure of trough-type bridge. The civil construction should be completed before the laying of the trough bridge, and the capping of the shaft should be completed to ensure the cleanness of the surrounding environment of the installation. The position of the holes through the wall and across the floor shall be accurate before the trough bridge is laid.

2、桥架型号

2. Bridge model

槽式桥架编写立柱托臂提料清单时应填写：名称+型号+托臂长度。如“工字钢立柱托臂JY-TB101-260（托臂长度L=槽宽+60mm）”。槽式桥架支架的配套连接螺栓要根据具体要求型号来订货，槽式桥架支架的表面处理主要有喷漆、镀锌两种工艺，在重腐蚀环境下可以采用镀锌工艺。

When preparing the lifting list of column bracket for trough bridge, fill in: name+model+bracket length. For example, "I-beam column bracket JY-TB101-260 (bracket length L=slot width+60mm)". The matching connecting bolts of the trough bridge support shall be ordered according to the specific requirements and models. The surface treatment of the trough bridge support mainly includes painting and galvanizing, which can be used in the heavily corrosive environment.

3、桥架长度

3. Bridge length

槽式桥架直线段的标准长度一般有2m、3m、4m、6m几种。槽式桥架弯通的内侧弯曲半径有50mm、100mm、150mm、200mm、300mm、400mm、600mm等。槽式桥架吊架编写提料清单时应填写：名称+高度H+横担长度L，例如：通丝双拉吊架，规格H=2000mm,L=360mm（通丝吊架默认横担长度=槽宽+60mm）。

The standard length of straight section of trough bridge is generally 2m, 3m, 4m and 6m. The inner bending radii of the trough bridge are 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 600mm, etc. When preparing the material lifting list for the trough type bridge hanger, the following items should be filled in: name+height H+cross arm length L, for example: through-wire double-pull hanger, specification H=2000mm, L=360mm (the default cross arm length of through-wire hanger=slot width+60mm).

4、桥架弯曲半径

4. Bending radius of bridge

槽式桥架弯通的弯曲半径小于300mm，应在弯头与直线段的连接处300mm-600mm处，单独设置一个支吊架。大于等于300mm时，还应该在弯通的中间位置加一个支、吊架。槽式桥架敷设时遇到电缆需要分支或拐弯，托盘或梯架的弯通、三通等的弯曲半径要大于敷设电缆的大弯曲半径，否则安装的桥架会对电缆产生损坏。

The bending radius of the trough bridge bend is less than 300mm, and a separate support and hanger shall be set at the junction of the elbow and the straight section between 300mm and 600mm. When it is greater than or equal to 300mm, a support and hanger should also be added at the middle of the bend. When laying the trough bridge, the cable needs to branch or turn. The bending radius of the tray or ladder elbow and tee should be greater than the large bending radius of the cable, otherwise the installed bridge will damage the cable.
