1.t has veryhighlightning current discharge capacity;
2.Single module impulse current can reach50kA(10/350us)at the maximum,which can preventvarious current including the direct lightning;
3.t is applied in the primary power supply protection ofdevice system where has higher lightning risk.It can becombined to use in the single phase and three phaselines;
4.t has advantagessuch as big impulse current,lowimperfect,andso on.Its core part consists of multistagegraphite gap.Reasonable design and sealed structureconsists of spark gap ensure the safedistance insidethe spark gap,which makes stable and reliable quality.
