The cable bridge is suitable for laying power cables and control cables in general industrial and mining enterprises indoor and outdoor. It can also be used for Telecom, radio and television departments to set up indoor and outdoor.

選擇電纜橋架根據電纜荷載及橋架安裝處的環境，以電纜橋架的載荷曲線為依據，來確定電纜橋架的類型和規格及立柱的間距、托臂的長度、電纜橋架的層次，立柱的長度等。

According to the cable load and the environment where the cable tray is installed, and based on the load curve of the cable tray, the type and specification of the cable tray, the spacing of the column, the length of the bracket arm, the level of the cable bridge and the length of the column are determined.

當電纜橋架的固定方式采用懸掛式且托臂為單側多層式安裝時，為了立注受力平衡，應選用對材載荷方式，敷設電纜橋架。

When the cable tray is suspended and the bracket is installed in one side and multi-layer, in order to balance the vertical injection force, the material loading mode should be selected to lay the cable bridge.

大跨距敷設電纜，可選用大跨距電纜橋架。

Long span cable tray can be selected for long span cable laying.

電纜橋架在穿越易受外來機械損傷的地區和日曬地區，應選用防護蓋板。當電纜槽或桁架式梯架需轉變分支時，可采用各種彎通連接。

The protective cover plate shall be selected for cable tray crossing the area vulnerable to external mechanical damage and sun exposure. When the cable tray or truss ladder needs to change branches, various elbow connections can be used.

選擇電纜橋架的支撐間距應小于允許支撐跨距。寬度應留有一定的備用空位，以便以后增添電纜用。

The support spacing of cable tray shall be less than the allowable support span. A certain spare space should be reserved for the width, so as to add the cable in the future.

電纜橋架的防腐措施為：塑料噴涂、鍍鋅鈍化、電鍍鋅(適用于輕防腐地區)熱浸鍍鋅、熱噴鋅（適用于重防腐地區)鍍鋅鎳合金等。熱浸鍍鋅電纜橋架用料厚度需增加0．5mm以上。

The anti-corrosion measures of cable tray are as follows: plastic spraying, galvanizing and passivation, electro galvanizing (applicable to light anti-corrosion areas) hot-dip galvanizing, hot-dip galvanizing (applicable to heavy-duty areas) zinc nickel alloy, etc. The thickness of hot-dip galvanized cable tray should be increased by more than 0.5mm.
