電纜橋架如何選擇
高分子電纜橋架分為槽式、托盤(pán)式和梯架式,由支架、托臂和安裝附件等組成。建筑物內橋架可以單獨架設,也可以附設在各種建(構)筑物和管廊支架上,應體現結構簡(jiǎn)只,造型美觀(guān)、配置靈活和維修方便等特點(diǎn)。經(jīng)濟快速的發(fā)展使得電纜橋架的使用率很高,它使得電線(xiàn)、電纜、光纜的設備具備了標準化、系列化、通用化水平。而電纜橋架安裝的環(huán)境各有不同,這就要求電纜橋架做到對環(huán)境的適應度要高,而高分子電纜橋架具有阻燃、防腐、絕緣好的優(yōu)點(diǎn)能夠應對環(huán)境對電纜橋架的影響。
Polymer cable tray is divided into trough type, tray type and ladder type, which is composed of support, bracket and installation accessories. The bridge in the building can be erected separately or attached to various buildings (structures) and pipe gallery supports, which shall reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. With the rapid economic development, the utilization rate of cable bridge is very high, which makes the equipment of wires, cables and optical cables have the level of standardization, serialization and generalization. The installation environment of cable bridge is different, which requires the cable bridge to have a high adaptability to the environment, and the polymer cable bridge has the advantages of flame retardant, anti-corrosion and good insulation, which can deal with the impact of the environment on the cable bridge.
電纜橋架有著(zhù)多種形式,主要是槽式、托盤(pán)式和梯架式、網(wǎng)格式等結構。由于輕巧化的設計,可以廣泛應用于各種建筑場(chǎng)所。室內的配電支架或者室外的露天建筑物。電纜橋架主要是支架,托臂和其他一系列的安裝配件。結構看起來(lái)十分簡(jiǎn)潔,沒(méi)有過(guò)多復雜的內部結構,靈活安裝,維修方便。正是由于電纜橋架的改良設計,分量輕,承載能力大,才使得在不同的用電環(huán)境中橋架都可以快速安裝和適用于大型的配電場(chǎng)景,在電纜鋪設計劃中發(fā)揮了重大作用。同時(shí)另外的槽式橋架更是具有良好的屏蔽功能,正是由于它是屏蔽式的結構,可以在嚴酷的環(huán)境下都有良好的保護效果,同時(shí)具有防塵功能,更好的保護電纜和橋架。不同的橋架有著(zhù)不同的優(yōu)點(diǎn)和缺陷,我們應根據場(chǎng)景選擇。
Cable tray has many forms, mainly trough type, tray type, ladder type, grid format and other structures. Due to the lightweight design, it can be widely used in various construction sites. Indoor power distribution support or outdoor open-air building. Cable tray is mainly a bracket, bracket and a series of other installation accessories. The structure looks very simple, without too many complex internal structures, flexible installation and convenient maintenance. It is because of the improved design of cable tray, light weight and large bearing capacity that the cable tray can be quickly installed and suitable for large-scale power distribution scenarios in different power consumption environments, and has played an important role in the national cable laying plan. At the same time, the other trough bridge has good shielding function. Because it is a shielding structure, it can have good protection effect in harsh environment. At the same time, it has dust-proof function to better protect cables and bridges. Different bridges have different advantages and disadvantages. We should choose them according to the scene.
電纜橋架選擇要做好前期的準備工作,包括環(huán)境、型號、電力系統情況等,如下:1、了解基本的情況:(4)確定安裝方式:根據場(chǎng)所的設置條件確定橋架的固定方式,選擇懸吊式、直立式、側壁式或是混合式,連接件和緊固件一般是配套供應的,此外,根據橋架結構選折相應的蓋板。 (5)繪出電纜橋架平、剖面圖,局部部位還應繪出空間圖,開(kāi)列材料表。 2、如與電力電纜橋架合用時(shí),應將電力電纜和弱電電纜各直一側,中間采用隔板分隔。3、弱電電纜與其它低電壓電纜合用橋架時(shí),應嚴格執行選擇具有外屏蔽層的弱電系統的弱電電纜,避免相互間的干擾。山東歐凱高分子材料有限公司打造綠色產(chǎn)品。
Preliminary preparations shall be made for the selection of cable tray, including environment, model, power system, etc., as follows: 1. Understand the basic situation: (4) determine the installation mode: determine the fixation mode of cable tray according to the setting conditions of the site, and select suspension type, vertical type, side wall type or hybrid type. Connectors and fasteners are generally supplied together. In addition, Select and fold the corresponding cover plate according to the bridge structure. (5) Plan and section drawings of cable tray shall be drawn, and space drawings shall be drawn for local parts, with material list listed. 2. If it is used with the power cable bridge, the power cable and weak current cable shall be straight on each side, and the middle shall be separated by partitions. 3. When the weak current cable and other low-voltage cables share the bridge, the weak current cable of the weak current system with external shielding layer shall be strictly selected to avoid mutual interference.

電纜橋架材料如何選擇?現在電纜橋架在生活中的使用已經(jīng)是很普遍的了,電纜橋架提高了電力系統的運輸,檢查修理也很方便,所以如果電纜橋架的質(zhì)量好的話(huà),使用壽命長(cháng)是在好不過(guò)的了,電纜橋架的材料可以選用冷軋鋼板,冷軋鋼板就是經(jīng)過(guò)冷軋生產(chǎn)的鋼板。冷軋是在室溫條件下將鋼板進(jìn)一步軋薄為目標厚度的鋼板。和熱軋鋼板比較,冷軋鋼板厚度更加準確,而且表面光滑、漂亮,同時(shí)還具有各種優(yōu)越的機械性能,特別是加工性能方面。因為冷軋原卷比較脆硬,不太適合加工,所以通常情況下冷軋鋼板要求經(jīng)過(guò)退火、酸洗及表面平整之后才交給客戶(hù)。
How to select cable tray materials? Now the use of cable bridge in life is very common. Cable bridge improves the transportation of power system and is convenient for inspection and repair. Therefore, if the quality of cable bridge is good, it is better to have a long service life. The material of cable bridge can be cold-rolled steel plate, which is the steel plate produced by cold rolling. Cold rolling is to further thin the steel plate to the target thickness at room temperature. Compared with hot-rolled steel plate, cold-rolled steel plate has more accurate thickness, smooth and beautiful surface, and also has various superior mechanical properties, especially processing properties. Because the cold-rolled original coil is brittle and hard, it is not suitable for processing, so generally, the cold-rolled steel plate is required to be delivered to the customer after annealing, pickling and surface leveling.
