电缆桥架和金属线槽有哪些区别呢?

电缆桥架是密接支撑电缆的刚性结构系统,是由槽式、托盘式或梯级式的直线段、弯通、三通、四通组件以及托臂(臂式支架)、吊架等构成。买卖宝上的桥架产品类型众多,产品优质,得到用户的广泛关注,众多产品选用优质冷轧钢板,表面工艺有冷镀锌、热镀锌、静电喷涂、防火涂料、烤漆等。
Cable bridge is a rigid structural system closely connected to support cables, which is composed of trough type, tray type or step type straight section, elbow, tee, cross components, arm (arm type support), hanger, etc. There are many types of bridge products on the trading treasure, and the products are of high quality, which are widely concerned by users. Many products are made of high-quality cold-rolled steel plate, and the surface technology includes cold galvanizing, hot galvanizing, electrostatic spraying, fire-retardant coating, baking paint, etc.
电缆桥架的外观有很多种,比如镀锌、喷塑、镀锌+喷塑。但线槽好像就是镀锌。桥架还分很多种,例如:梯形桥架、金属线槽,还有玻璃钢桥架等等。电缆桥架和金属线槽的区别具体如下:
There are many kinds of appearance of cable tray, such as zinc plating, plastic spraying, zinc plating + plastic spraying. But the trunking seems to be galvanized. There are many kinds of cable tray, such as trapezoidal cable tray, metal trunking, FRP cable tray and so on. The differences between cable tray and metal trunking are as follows:
1.电缆桥架一般宽度>200mm,金属线槽宽度<200mm。
1. The general width of cable tray is more than 200 mm, and the width of metal trunking is less than 200 mm.
2.电缆桥架主要用于敷设电缆,金属线槽主要用于敷设导线。
2. Cable tray is mainly used for laying cables, and metal trunking is mainly used for laying wires.
3.电缆桥架型式有梯式、槽式、托盘式、组合式等多种,而在材质和防腐处理方面又分铝合金、玻璃钢、冷(热)轧钢板镀锌、喷涂等。金属线槽就一种,一般用热轧钢板作成。
3. There are many types of cable tray, such as ladder type, trough type, tray type, combined type and so on. In terms of material and anti-corrosion treatment, it is divided into aluminum alloy, glass fiber reinforced plastic, cold (hot) rolled steel plate galvanizing, spraying and so on. Metal raceway is one kind, generally made of hot rolled steel plate.
4.电缆桥架敷设时一般应考虑其荷载、挠度、填充率。
4. The load, deflection and filling rate of cable tray should be considered when laying.
5.金属线槽约等于槽式电缆桥架,只不过某些金属线槽尺寸较小罢了(地面线槽除外)。有些从桥架下来需接到配电柜的线都是走到金属线槽里再接入配电柜.
5. Metal trunking is about the same as cable tray, but some metal trunking is smaller (except ground trunking). Some wires from the bridge to the power distribution cabinet are connected to the metal trunking
6.桥架有好多种、是开放式的,线槽多数是封闭的(塑料&amp;金属)7.两种敷设方式载流量不同
6. There are many kinds of bridge, which are open, and most of the trunking are closed (plastic &amp; metal). 7. The current carrying capacity of the two laying methods is different
8.桥架一般裁质是冷轧钢板,而线槽用的是镀锌铁皮。
8. The bridge is generally made of cold-rolled steel plate, while the trunking is made of galvanized iron sheet.
9.从外观跟材质上分:我的观点是桥架比金属线槽厚,安装相对牢固。
9. From the appearance and material: my point of view is that the bridge is thicker than the metal trunking, and the installation is relatively firm.
10.既然规范有对桥架、金属线槽的分别说明,它们在材质方面就有区别。《民用建筑电气设计规范》上有对应条款的要求。
10. Since the specification has a separate description of bridge and metal trunking, they are different in material. There are corresponding requirements in code for electrical design of civil buildings.
