Cable tray generally refers to a commodity extended to prevent high-voltage cables. It can prevent high-voltage cables from being harmed and damaged by the external environment and uncertain factors on the premise of normal power operation, and then ensure the integrity of power consumption and power supply system.

電纜橋架由支撐架、托臂和機器設備配件構成。電纜橋架能夠在房子房屋建筑內獨立安裝，工業設備能夠鋪設在各種各樣房子的房屋建筑和固定支架上，盡數零配件能夠根據熱鍍鋅處理，工業設備在屋子和戶外都是有非常好的防腐蝕實際效果。

The cable tray is composed of support frame, supporting arm and machine equipment accessories. The cable bridge can be installed independently in the house, the industrial equipment can be laid on the house buildings and fixed supports of various houses, and all spare parts can be treated according to hot galvanizing. The industrial equipment has a very good practical effect of anti-corrosion in the house and outdoors.

電纜橋架規格挑選

Cable tray specification selection

1.復合環氧樹脂電纜槽的總寬度和高寬比應按表選擇，并應滿足電纜真實充電率不超過相關技術標準的標準值。電力電纜可使用40-50%，變頻電纜可使用50-70%。此外，還應保留10-25%的配方開發趨勢產能。

1. The total width and aspect ratio of composite epoxy resin cable tray shall be selected according to the table, and the actual charging rate of the cable shall not exceed the standard value of relevant technical standards. 40-50% for power cables and 50-70% for frequency conversion cables. In addition, 10-25% of the formula development trend capacity should be retained.

2.各種類型的彎曲和裝配規格應符合工程項目布置標準，并與橋梁相容。

2. Various types of bending and assembly specifications shall comply with the project layout standards and be compatible with the bridge.

3.支護和支護規格的選擇應當按照橋梁規格、覆蓋層數、跨度等標準進行。并應考慮載荷的規定。

3. The selection of support and support specifications shall be carried out in accordance with bridge specifications, number of covering layers, span and other standards. The provisions of load shall be considered.

4.橋架橫截面積的挑選見表橋架上高壓電纜互聯網中任一路線的較大全自動過電流量防止的額定電壓值或整時間常數(A)橋架截面允許小值(mm2)

4. The selection of the cross-sectional area of the bridge is shown in the table. The rated voltage value or the whole time constant (a) of the larger automatic overcurrent prevention of any route in the high-voltage cable Internet on the bridge (mm2)

電纜橋架的型號為：

The model of cable tray is:

1、高壓電纜橋主要是支撐點和儲放高壓電纜的支撐架。在工程項目上應用廣泛，一般高壓電纜是必的，因此電纜橋架也變成必的了，在建筑施工中具有非常大的功效。

1. High voltage cable bridge is mainly a support point and a support frame for storing high voltage cables. It is widely used in engineering projects. Generally, high-voltage cable is necessary, so cable bridge has become necessary, which has great effect in building construction.

2、托盤式電纜橋架是原油、化工廠、輕工業、通訊器材等層面運用普遍的一種。它具備重量較輕、荷載大、造型設計美觀大方、構造簡易、安裝便捷等優勢。托盤式電纜橋架關鍵用以動力電纜的安裝，也合適于變頻電纜的鋪設。

2. Tray type cable tray is widely used in crude oil, chemical plants, light industry, communication equipment and other aspects. It has the advantages of light weight, large load, beautiful design, simple structure and convenient installation. Tray type cable tray is mainly used for the installation of power cable and the laying of frequency conversion cable.

3、梯階式電纜橋架。梯階式電纜橋架是依據世界各國相關材料而改設計方案的。它具備重量較輕、低成本、造型設計安裝便捷、排熱、透氣性好等優勢。關鍵用以直徑很大高壓電纜的鋪設，合適于高、底壓動力電纜的鋪設。

3. Ladder type cable tray. The ladder type cable tray is designed according to the relevant materials all over the world. It has the advantages of light weight, low cost, convenient modeling design and installation, heat removal and good air permeability. The key is to lay high-voltage cables with large diameter, which is suitable for the laying of high and bottom pressure power cables.

4、槽式電纜橋架。槽式電纜橋架是一種全封閉式型電纜橋架。它適用鋪設計算機電纜、電力電纜、熱電阻高壓電纜以及他高精度系統軟件的變頻電纜等。關鍵用以變頻電纜的屏蔽掉影響和重浸蝕中環境高壓電纜的防止。

4. Trough type cable tray. Trough type cable tray is a fully enclosed cable tray. It is suitable for laying computer cables, power cables, thermal resistance high-voltage cables and frequency conversion cables of other high-precision system software. The key is to shield off the influence of frequency conversion cable and prevent the environmental high-voltage cable in re etching.
