It should switch off the weld machine; the welding tongs should put on the insulator or hang on. Don't touch the member.

焊接完后及时关闭焊机，将焊钳放在绝缘物品上或悬挂起来，不得与构件接触。

The bending deformation of V-shape composite insulator string under strong wind may cause the risk of ball head falling off and string falling apart.

型复合绝缘子串在大风作用力下受到弯曲变形，有球头脱落造成掉串的风险。

So we have started off with the conductor on the bottom, an insulator, a conductor in the middle.

所以我们一开始就是底部一层导体，一层绝缘体，中间再一层导体。
