　　電力電纜橋架敷設電纜橋架敷設方式的優(yōu)點很突出，相比于其他方式，具有很強的適用性和完善性，不管是電纜跟數(shù)較多的主干線路還是根數(shù)較少的配電線路，一般都可使用此種方式。電纜橋架不單獨占用電纜通道，節(jié)省空間，而且由于電纜敷設在空氣中，散熱效果好，維修方便，增設新電纜也比較容易。不同的電纜在橋架上敷設時需要分層排列，從上到下的排列順序依次是弱電電纜、控制電纜，低壓電力電纜、高壓電力電纜。這種排列方式是為了阻隔電纜之間的互相的影響，將干擾信號排除在外，不僅有利于電纜的散熱，也有利于后期的檢修和維護。當電力電纜和控制電纜在同一橋架層上安裝時，我們要采用有效地方式將強電和弱電隔離開了，防止互相干擾，一般使用金屬隔板隔開。

　　The advantages of the cable tray laying method for power cables are very prominent. Compared with other methods, it has strong applicability and completeness. Whether it is the main line with more cables or the distribution line with fewer cables, this method can generally be used. The cable tray does not occupy the cable channel separately, saving space. Moreover, due to the cable being laid in the air, the heat dissipation effect is good, and maintenance is convenient. Adding new cables is also relatively easy. When laying different cables on the bridge, they need to be arranged in layers. The order of arrangement from top to bottom is weak current cables, control cables, low-voltage power cables, and high-voltage power cables. This arrangement is to block the mutual influence between cables and exclude interference signals, which is not only beneficial for cable heat dissipation, but also for later maintenance and repair. When power cables and control cables are installed on the same bridge layer, we need to use an effective method to separate strong and weak currents to prevent mutual interference. Generally, metal partitions are used to separate them.

　　電力電纜隧道敷設電力電纜敷設于隧道內(nèi)，隧道由于空間較大，能夠容納很多電纜，所以這種敷設方式一般用于電纜線路比較煩多復雜的地區(qū)（比如出線較多的大型發(fā)電廠）或路徑難度加大區(qū)段（如穿越機場跑道或江底），位于有腐蝕性液體或經(jīng)常有地下水流溢的場所，電纜隧道是未來城市電力系統(tǒng)改造發(fā)展的一個重要方向，在未來，城市電纜應用的范圍會越來越廣，數(shù)量越來越多，應該需要更完善的配套設備。

　　Power cable tunnel laying: Power cables are laid inside tunnels. Due to their large space, tunnels can accommodate a large number of cables, so this laying method is generally used in areas with more complicated cable lines (such as large power plants with more outgoing lines) or sections with increased path difficulty (such as crossing airport runways or river bottoms), located in places with corrosive liquids or frequent groundwater overflow. Cable tunnels are an important direction for the future development of urban power system transformation. In the future, the scope and quantity of urban cable applications will become wider and more numerous, and more complete supporting equipment should be needed.

　　一、應用分析電纜一般多使用在城市繁華地段，這些地方對市容要求較高，還包括一些旅游景點區(qū)域，現(xiàn)在很多地方都將電纜取代了架空線，因為電纜有很多的優(yōu)點如下所列：

　　1、 Application analysis cables are generally used in bustling urban areas, which have high requirements for urban appearance and also include some tourist attraction areas. Nowadays, many places have replaced overhead lines with cables because they have many advantages as follows:

　　1.不受自然氣象條件的影響；

　　1. Not affected by natural meteorological conditions;

　　2.不受沿線樹木生長的影響；

　　2. Not affected by the growth of trees along the route;

　　3.有利于城市環(huán)境的美化；

　　3. Beneficial for beautifying the urban environment;

　　4.不占地面走廊，多路電纜可共用一條地下通道，節(jié)約空間；

　　4. It does not occupy the ground corridor, and multiple cables can share one underground passage, saving space;

　　5.電纜的保護性能高，確保人身，防觸電；

　　5. The protective performance of cables is high, ensuring personal safety and preventing electric shock;

　　6.易于維護和檢修。

　　6. Easy to maintain and repair.

　　二、基于上述幾個優(yōu)點，目前中低壓配電線路在以下情況下應采用電纜線路：

　　2、 Based on the above advantages, cable lines should be used for medium and low voltage distribution lines in the following situations:

　　1.在繁華的市中心和對環(huán)境美觀性要求高的場所；

　　1. In bustling city centers and places with high requirements for environmental aesthetics;

　　2.架空線路不能到的地方；

　　2. Places that cannot be reached by overhead lines;

　　3.對于性和可靠性要求高的地方；

　　3. Places with high requirements for safety and reliability;

　　4.旅游觀光區(qū)；

　　4. Tourist and sightseeing areas;

　　5.容易受惡劣天氣影響的地方，不適合架空線路的敷設就要使用電纜。而這幾年比較流行的預分支電纜也得到了廣泛應用，一般用于低壓配電系統(tǒng)，用于高層民用建筑電氣豎井的垂直配電干線，隧道、機場、橋梁、公路等照明配電干線等。

　　5. In areas that are susceptible to adverse weather conditions and are not suitable for laying overhead lines, cables should be used. And in recent years, the popular pre branch cables have also been widely used, generally used in low-voltage distribution systems, vertical distribution trunk lines for electrical shafts in high-rise civil buildings, lighting distribution trunk lines in tunnels, airports, bridges, highways, etc.電力電纜橋架敷設電纜橋架敷設方式的優(yōu)點很突出，相比于其他方式，具有很強的適用性和完善性，不管是電纜跟數(shù)較多的主干線路還是根數(shù)較少的配電線路，一般都可使用此種方式。電纜橋架不單獨占用電纜通道，節(jié)省空間，而且由于電纜敷設在空氣中，散熱效果好，維修方便，增設新電纜也比較容易。不同的電纜在橋架上敷設時需要分層排列，從上到下的排列順序依次是弱電電纜、控制電纜，低壓電力電纜、高壓電力電纜。這種排列方式是為了阻隔電纜之間的互相的影響，將干擾信號排除在外，不僅有利于電纜的散熱，也有利于后期的檢修和維護。當電力電纜和控制電纜在同一橋架層上安裝時，我們要采用有效地方式將強電和弱電隔離開了，防止互相干擾，一般使用金屬隔板隔開。
