槽式橋架、托盤式橋架、鋁合金橋架和網(wǎng)格式橋架。

Trough type bridge, tray type bridge, aluminum alloy bridge, and mesh type bridge.

槽式橋架和托盤式橋架的區(qū)別：

The difference between trough bridge and tray bridge:

槽式電纜橋架與金屬托盤電纜橋架是大多能夠鋪設(shè)電線電纜，橫斷面、結(jié)構(gòu)形式不一樣罷了。封閉式的金屬線槽、無蓋的拖盤也有梯架都?xì)w屬于電纜橋架，三種電纜橋架的結(jié)構(gòu)形式不一樣，一些性能也是有差別，例如防護(hù)性以槽式比較好、梯架較差，但自然通風(fēng)制冷性卻反過來。

Both trough cable trays and metal tray cable trays are capable of laying wires and cables, with different cross-sectional and structural forms. Enclosed metal cable trays, uncovered trays, and ladders are all classified as cable trays. The structural forms of the three types of cable trays are different, and some of their performance also varies. For example, the protection is better in the tray type than in the ladder type, but the natural ventilation cooling performance is the opposite.

槽式電纜橋架的優(yōu)勢在于屏蔽和防腐，主要適用于鋪設(shè)截面小但是數(shù)量卻多的電線電纜;而托盤式纜橋架優(yōu)勢在于載荷大和散熱好，主要就是用于鋪設(shè)截面大但是數(shù)量比較小的電力電纜。

The advantage of trough cable trays lies in shielding and anti-corrosion, mainly suitable for laying wires and cables with small cross-sections but large quantities; The advantage of tray type cable trays lies in their high load capacity and good heat dissipation, mainly used for laying power cables with large cross-sections but relatively small quantities.

從外形來看，槽式電纜橋架是一種全封閉型電纜橋架。托盤橋架一般指的是有孔的槽式橋架。由于開了散熱孔，托盤式橋架板材的厚度要更厚些。

From the appearance, the trough cable tray is a fully enclosed cable tray. Tray trays generally refer to perforated trough trays. Due to the opening of heat dissipation holes, the thickness of the tray type bridge board needs to be thicker.
