The bus bridge is also called the bridge type connection, and the two power supply is introduced with the cross connection circuit breaker BCD to connect the main connection with the two transformers. Compared with the simplified single bus connection, the number of circuit breakers is reduced.

　　根據跨接橋斷路器的位置不同，分為內接線橋和外接線橋。其中內接線橋適用于線路較長，負荷曲線比較平穩的變電位置；外接線橋則適用于線路較短，負荷曲線變化較大的變電位置。

　　According to the different position of the cross bridge circuit breaker, it is divided into the inner line bridge and the external connection bridge. The internal bridge is suitable for the long transmission line and the load curve is relatively stable. The external connection bridge is suitable for the substation with short circuit and large load curve.

　　網格式電纜橋架由廠家加工成直段送安裝現場，各種角度的轉角、三通、四通、變徑、標高變化等部件都可以根據實際情況采用直段橋架直接加工而成，無需提前去工廠定制。這個特點對于設計、安裝來說都非常簡便、靈活多變，可大幅度縮短安裝時間。既提高了施工工期，又節約了人工費用。

　　The mesh type cable bridge is directly processed by the manufacturer to the installation site. All angles, three links, four links, variable diameters and elevation changes can be directly processed by straight section bridge according to the actual situation, without having to go to factory customization in advance. This feature is very simple, flexible and flexible for the design and installation, and can greatly shorten the installation time. It not only improves the construction time, but also saves the artificial cost.

　　當今時代是信息化社會，增加、更換新設備是必然的，線纜的增加、更換及拆除將更為頻繁，網格式電纜橋架為開放式結構，線纜布放具有靈活性、快捷性的特點，能夠適應不斷變化的應用需求。

　　The present era is the information society, and increase the replacement of new equipment is inevitable, the increase of cable replacement and demolition will be more frequent, grid cable tray is an open structure, characteristics of cable laying is flexible, fast, able to adapt to changing application needs.
