电缆桥架2分加隔板用途是什么?

在同一电缆桥架内同时敷设动力电缆和低压仪表信号电缆时起到分隔作用。例如300*150型的电缆桥架若需要加隔板的话,那它的表示方法一般就是:(200+100)*150,也就是说把300mm宽的电缆桥架分成200mm宽和100mm宽的两个区。
The power cable and low-voltage instrument signal cable are laid in the same cable bridge at the same time to play a separation role. For example, if the 300 * 150 cable tray needs to be provided with a partition, its representation method is generally (200+100) * 150, that is, the 300 mm wide cable tray is divided into two areas of 200 mm wide and 100 mm wide.
消防回路与普通回路、同一负荷的2路电缆均需分开敷设,在同一桥架中敷设时应加隔板。消防线路有防火要求,有时须在耐火槽盒内敷设。若普通电缆与消防电缆在同一槽盒内敷设,因载流量降低很多(0.38),会增加普通配电回路电缆的投资,因此,普通电缆单独在电缆体架中敷设更合理。若消防采用矿物绝缘电缆,消防与非消防均可在梯架中敷设,则不存在上述问题,只需设隔板即可。
Fire-fighting circuit, common circuit and 2-way cables with the same load shall be laid separately, and clapboard shall be added when laying in the same bridge. The fire line has fire protection requirements, and sometimes it must be laid in the fire resistant tank box. If common cables and fire cables are laid in the same tray, the investment of common distribution circuit cables will be increased because the current carrying capacity is reduced a lot (0.38 at least). Therefore, it is more reasonable for common cables to be laid separately in the cable body frame. If mineral-insulated cables are used for fire protection, both fire protection and non-fire protection can be laid in the ladder, there is no such problem, and only a partition is required.

As shown below:
根据不同需求,一般有两种隔板型号,其安装方法也不一样:
According to different requirements, there are generally two types of diaphragm, and their installation methods are also different:
1、固定隔板,即在桥架槽体内,按客户要求的位置或尺寸,焊接隔板。缺点:灵活性差,施工时万一设计有变动,无法更改。优点:施工方省时、省工;2.活动隔板:
1. Fix the partition, that is, weld the partition in the tray groove according to the position or size required by the customer. Disadvantages: poor flexibility. In case of design change during construction, it cannot be changed. Advantages: the construction party saves time and labor; 2. Movable partition:
2、单独加工隔板,在隔板底部加工出螺眼,使用螺栓与桥架槽体连接。缺点:费时、费工,施工时要对槽体需要位置进行螺眼加工。优点:灵活性高,随时根据要求改变设计。
2. Separately process the baffle plate, machine the bolt hole at the bottom of the baffle plate, and connect it with the tray trough with bolts. Disadvantages: time-consuming and labor-intensive. During construction, screw holes shall be processed at the required positions of the tank body. Advantages: high flexibility, design can be changed at any time according to requirements.
使用隔板前,要根据需用电缆数量、直径、间隔距离来确定桥架的规格、型号等,需要注意:
Before using the partition, first determine the specification and model of the bridge according to the number, diameter and spacing distance of the cables required, and pay attention to:
1、选择电缆桥架宽度时应留有一定的备用空位,以便为今后增添电缆和隔板做预留。
1. When selecting the width of cable tray, a certain amount of spare space shall be reserved for the future addition of cables and partitions.
2、当电力电缆和控制电缆较少时,可同一电缆桥架安装,但中间要用隔板将电力电缆和控制电缆隔开敷设。。
2. When there are few power cables and control cables, they can be installed on the same cable bridge, but the power cables and control cables should be separated and laid by partitions..
