通过加宽导线与地线之间的距离，绝缘线与金属线之间的部分，把电线从干的顶部移开来减少高压线的危险。
Power lines can be made less dangerous by widening the gap between conducting and ground wires, insulating wires and metal parts, and moving wires farther away from pole tops.
可以通过加宽导线和地线的间距来减少危险性、将电线和金属元件绝缘和将电线移动到离电线杆顶部较远的地方。
Power lines can be made less dangerous by widening the gap between conducting and ground wires, insulating wires and metal parts, and moving wires farther away from pole tops.
