槽式橋架是現(xiàn)代電氣工程中應(yīng)用為廣泛的一種無(wú)孔托盤橋架，槽式橋架的橋架材質(zhì)、橋架品種樣式、橋架的規(guī)格、橋架表面防護(hù)都屬于槽式橋架型號(hào)信息。槽式橋架標(biāo)準(zhǔn)長(zhǎng)度一般為2米，當(dāng)然也有3米、4米、6米的，彎曲半徑有200mm、400mm、600mm等。更多詳細(xì)內(nèi)容濟(jì)南電纜橋架廠家認(rèn)為您可以參考下面：

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、槽式橋架

1. Trough-type bridge

水平槽式橋架敷設(shè)的端部、進(jìn)出接線箱的轉(zhuǎn)角處、轉(zhuǎn)彎處、穿越變形縫的兩端、水平三通的三個(gè)端點(diǎn)、水平四通的四個(gè)端點(diǎn)，都應(yīng)該增設(shè)支吊架。鍍鋅托盤或梯架兩節(jié)進(jìn)行槽式橋架敷設(shè)時(shí)，中間的連接片如果不用跨接線，則需要在其兩端安裝不少于2個(gè)帶防松螺帽或防松墊圈的固定螺栓。

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.

低壓動(dòng)力電纜適合采用梯級(jí)式、托盤式、組合式結(jié)構(gòu)的槽式橋架，高壓動(dòng)力槽式橋架適合采用梯級(jí)式、托盤式結(jié)構(gòu)的槽式橋架。槽式橋架敷設(shè)之前土建施工應(yīng)當(dāng)已經(jīng)完成，豎井井道的封頂已完成，保證安裝周邊環(huán)境的整潔干凈。槽式橋架敷設(shè)之前穿墻和跨樓層的孔洞位置要保證準(zhǔn)確。

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、橋架型號(hào)

2. Bridge model

槽式橋架編寫立柱托臂提料清單時(shí)應(yīng)填寫：名稱+型號(hào)+托臂長(zhǎng)度。如“工字鋼立柱托臂JY-TB101-260（托臂長(zhǎng)度L=槽寬+60mm）”。槽式橋架支架的配套連接螺栓要根據(jù)具體要求型號(hào)來(lái)訂貨，槽式橋架支架的表面處理主要有噴漆、鍍鋅兩種工藝，在重腐蝕環(huán)境下可以采用鍍鋅工藝。

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、橋架長(zhǎng)度

3. Bridge length

槽式橋架直線段的標(biāo)準(zhǔn)長(zhǎng)度一般有2m、3m、4m、6m幾種。槽式橋架彎通的內(nèi)側(cè)彎曲半徑有50mm、100mm、150mm、200mm、300mm、400mm、600mm等。槽式橋架吊架編寫提料清單時(shí)應(yīng)填寫：名稱+高度H+橫擔(dān)長(zhǎng)度L，例如：通絲雙拉吊架，規(guī)格H=2000mm,L=360mm（通絲吊架默認(rèn)橫擔(dān)長(zhǎng)度=槽寬+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、橋架彎曲半徑

4. Bending radius of bridge

槽式橋架彎通的彎曲半徑小于300mm，應(yīng)在彎頭與直線段的連接處300mm-600mm處，單獨(dú)設(shè)置一個(gè)支吊架。大于等于300mm時(shí)，還應(yīng)該在彎通的中間位置加一個(gè)支、吊架。槽式橋架敷設(shè)時(shí)遇到電纜需要分支或拐彎，托盤或梯架的彎通、三通等的彎曲半徑要大于敷設(shè)電纜的大彎曲半徑，否則安裝的橋架會(huì)對(duì)電纜產(chǎn)生損壞。

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.
