When the current flow capacity is increased to 100kA, the damage rate of the arrester is greatly reduced (taking Hunan as an example, the annual damage rate is reduced from 19% to 0.3%), and the probability of explosion of the arrester under high amplitude lightning is extremely low. It can withstand multiple lightning strikes and effectively protect electrical equipment such as transformers and ring cabinets.
Rated voltage | 17kV |
Nominal discharge current | 10kA |
2ms square wave current | 400A |
1mA reference voltage | 25kV |
4/10μs high current impulse | Up to 120kA |

Since 2017, nearly 280,000 10kV lightning protection insulators and 80,000 10kV gapless arresters have been applied to 235 10kV lines in China. In Hunan alone, the line lightning strike trip rate dropped from 5.29 times/(100km.a) to 0.31 times/(100km.a), a drop rate as high as 94%; wire disconnection and equipment damage caused by lightning strikes were greatly reduced, effectively improving the line Lightning protection level.
