◎箱式站起吊应用专用起吊工具，起吊部分必须按箱式站的标明部位。
◎箱式站底部与基础结合处，需用水泥浆抹封，以防水进入电缆室。
◎电缆进入套管后。
其缝隙必须密封，以防虫、水进入。
箱式站投运前必须检查下列箱式站底部与基础结合处必须水平，如遇各门开启有卡住现象，这是因为基础平面不平所至必须调整箱式变电站与基础面结合水平。
调整方法在箱式变电站底部与基础而缝隙处填塞薄铁片直至各室门开户灵活即可。
当整机装配完成后，装车发运必须注意整台箱体应和车前车后有一定距离，防止车在行路中因刹车而前后撞击，同时箱式站底架和车底板必须用电焊焊牢，再用钢丝把底架和车底绞紧，并用绳索从顶盖到车底分几道上下扎紧。
凡绳索扎到之处必须用纸板或其它软物垫好以防涂层表面损伤。
为使运行中箱式站保持完好，最好半年或一年后对内部和外,部进行清扫和擦一次。
如发现因安装或运输中箱体外表面弄脏，可用洗涤剂擦刷，用清水冲洗即可。
