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.

　　根据跨接桥断路器的位置不同，分为内接线桥和外接线桥。其中内接线桥适用于线路较长，负荷曲线比较平稳的变电位置；外接线桥则适用于线路较短，负荷曲线变化较大的变电位置。

　　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.

　　网格式电缆桥架由厂家加工成直段送安装现场，各种角度的转角、三通、四通、变径、标高变化等部件都可以根据实际情况采用直段桥架直接加工而成，无需提前去工厂定制。这个特点对于设计、安装来说都非常简便、灵活多变，可大幅度缩短安装时间。既提高了施工工期，又节约了人工费用。

　　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.

　　当今时代是信息化社会，增加、更换新设备是必然的，线缆的增加、更换及拆除将更为频繁，网格式电缆桥架为开放式结构，线缆布放具有灵活性、快捷性的特点，能够适应不断变化的应用需求。

　　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.
