font-family: "PingFang SC", Helvetica, "Microsoft YaHei", Arial, sans-serif; color: rgb(102, 102, 102); white-space:

font-family: "PingFang SC", Helvetica, "Microsoft YaHei", Arial, sans-serif; color: rgb(102, 102, 102); white-space: normal;">　　2)可以在停電檢修時將接觸不好的地方的漆刮掉,讓變壓器各零部件接觸良好。</div><div microsoft="" pingfang=""
