Analysis shows that this is mainly due to not install over-voltage protector in across all tower, generally is a fundamental towerinsulation installed a set of over-voltage protector.
The lightning protection could be improved by means of decreasing grounding resistance of tower, installing line type surge arrester and side lightning rod as well as increasing the insulation level.
采取杆塔降阻、装设线路避雷器、侧向避雷针和加强绝缘等多种措施后，防雷保护效果较好。

The utility model relates to a spray cooling tower for resolving the problem of current spray cooling tower as poor heat insulation effect.
