先了解濟南電纜橋架的組成、布局、和設計，然后選擇適合的濟南電纜橋架安裝。

First, understand the composition, layout, and design of Jinan cable trays, and then select the appropriate Jinan cable tray for installation.

電纜橋架和立柱是電纜橋架安裝的兩個主要組成部分。在橋架施工中，要焊接立柱。立柱的長度、方向和焊接位置需要確定。柱子排列好后，整個橋將形成一個原型。電纜橋架安裝時，可根據橋架的連接和施工規(guī)范增加立柱。

Cable trays and columns are the two main components of cable tray installation. In bridge construction, the first step is to weld the columns. The length, direction, and welding position of the column need to be determined. After the columns are arranged, the entire bridge will form a prototype. When installing cable trays, columns can be added according to the connection and construction specifications of the trays.

濟南電纜橋架的安裝需要確定電纜橋架的數量和間距、電纜橋架的規(guī)格以及橋架的連接形式。同時，在冶金工程施工中，電纜橋架的施工可分為電氣室部分和電纜隧道部分。電氣室中電纜橋架的布局相對復雜，因為設計了許多系統，并且對兩個安裝位置給予了不同的考慮。

The installation of cable trays in Jinan requires determining the quantity and spacing of cable trays, the specifications of cable trays, and the connection form of trays. Meanwhile, in metallurgical engineering construction, the construction of cable trays can be divided into electrical room and cable tunnel sections. The layout of cable trays in the electrical room is relatively complex, as many systems have been designed and different considerations have been given to the two installation locations.

濟南防火電纜橋架的設計是一個系統工程。我們應該顧全大局，把握整個項目的電氣系統，從整個電氣系統的電路設計來考慮電纜橋架的布局。因此，為了合理優(yōu)化電纜橋齒條的設計，有必要對整個電氣高壓系統、低壓電力系統、變頻傳動系統、自動控制系統等有一個清晰的了解。

The design of Jinan fireproof cable tray is a systematic project. We should consider the overall situation, grasp the electrical system of the entire project, and consider the layout of cable trays from the perspective of the circuit design of the entire electrical system. Therefore, in order to optimize the design of cable bridge racks reasonably, it is necessary to have a clear understanding of the entire electrical high-voltage system, low-voltage power system, variable frequency drive system, automatic control system, etc.

濟南防火電纜橋架按電纜電壓等級分層，每層橋架的布置和安裝按電壓等級自上而下排列。這種布置不僅可以減少對電纜的電磁干擾，而且有助于冷卻電力電纜和方便敷設大截面電纜。

Jinan fireproof cable trays are layered according to cable voltage levels, and the layout and installation of each layer of trays are arranged from top to bottom according to voltage levels. This arrangement not only reduces electromagnetic interference to cables, but also helps to cool power cables and facilitate the installation of large cross-sectional cables.

濟南電纜橋架的鋪設檢查高壓電纜層的布局，因此高壓供配電系統相對簡單。根據本發(fā)明的高壓配電系統，確定高壓電纜的來源和行走路徑，從而確定電纜橋架高壓電纜層的行走路徑。高壓層電纜橋架的規(guī)格和層數可以根據高壓電纜占用的橋架空間來確定。三芯高壓電纜只能單層敷設，不能分層敷設。單芯高壓電纜一次只能鋪設一層。電纜之間應保持一定的距離，以確保電纜散熱。高壓電纜橋架確定后，根據現場施工的施工過程確定配電機制，估算所需電纜的尺寸和數量，確定橋架的方向和水平。

The laying of cable trays in Jinan first checks the layout of the high-voltage cable layer, so the high-voltage power supply and distribution system is relatively simple. According to the high-voltage distribution system of the present invention, the source and walking path of the high-voltage cable are determined, thereby determining the walking path of the high-voltage cable layer of the cable tray. The specifications and number of layers of high-voltage cable trays can be determined based on the tray space occupied by high-voltage cables. Three core high-voltage cables can only be laid in a single layer and cannot be laid in layers. Single core high-voltage cables can only be laid in one layer at a time. A certain distance should be maintained between cables to ensure heat dissipation. After the high-voltage cable tray is determined, the distribution mechanism is determined based on the construction process on site, the size and quantity of required cables are estimated, and the direction and level of the tray are determined.
