The question of earthing switch(ES) switching induced current was present in this paper, the feature of static and electromagnetism induction of common-tower double-circuit lines was also present.
The unique design guarantees continuous air supply at switching of the absorbing tower as well as low noise.
别具一格的设计，具有确保吸附塔切换时无断气，连续供气、低噪音的特点。
