In order to meet the need of long-distance and large-capability electricity transmission, the extra-high tension electricity transmission lines are widely used.

为了满足远距离、大容量输电和联网的需要，超高压输电目前已经广泛使用。

When the electric power lines fall onto the upper side, the high tension electricity can not pass through the insulation protective sleeve for the user lines, and the fatal accident can be avoided.

当有电力线跌落到上面时，高压电无法穿过下户线绝缘保护套，就可避免引起严重事故。

It could also mean clearing of forest and blasting of mountainsides to rig high tension power lines in once-picturesque environments.
