【功能概述】
BRCM默认提供了一些列常用的电压等级以供选择：低压、中压、控制、仪表布线、通信
但是有时候用户也需要定制化的电压等级，BRCM支持用户自定义电压等级，来满足不同的工程设计需要。
【功能详解】
1.在管理-选项-电缆数据中选择电缆电压等级，添加一个电压等级，例如HV：
2.同样在选项中，打开桥架规范，在桥架类别中找到电压等级，点击后方的“...”：
3.同样添加一个桥架电压等级，同样命名为HV，并将其选中；将右侧的未关联的电缆电压等级中的HV与之通过左相箭头，与之关联：
完成后，在各层对话框中点击应用/确定来保存编辑结果。
4.在电缆清册导入配置文件cable list.xml中，仿照已有的电压等级，添加新的电压等级相关信息：
这里提供一个示例文件：

5.这样就可以正常布置新电压等级的桥架，并导入对应电压等级电缆进行敷设。
