Lightning stroke is one of the important reasons that result in powerfailure. Tower lightning surge response performance is the important factor deciding transmission line lightning over-voltage.
雷击是导致输电线路故障的重要原因之一，杆塔的雷电冲击响应特性是决定输电线路雷电过电压的重要因素。

It has big power range, high transmission efficiency and transmission ratio correctly, long using life, etc, but from the failure parts, gear is the most vulnerable parts of the fault.
The failure of high voltage power supply equipment, especially the earthing failure of high voltage powertransmission line, will bring great impact on the construction site.
