ThunderGuard series ESE Lightning Arrester, with unique design philosophy, adopts synthesis techniques of leader discharge, impedance to limit current, air-gap discharge etc to produce leader channel in advance, improve lightning effect, reduce discharge voltage and change the discharge process of lightning current.

Thus it broaden the lightning wave, flatten the leading wave, decrease the amplitude and enlarge the scope of protection avoiding side striking and shielding failure then finally actively suppress the damage of Ground Potential

Counterattack. Therefore it is an ideal device to prevent direct lightning.



  • Central bar
  • Reflector
  • Trigger gear
  • Exciter
  • Dead plate of exciter
  • Trigger gear, reflector and central bar all are insulating
  • Reflector and central bar show good electrical connection to the earth
  • The base of exciter is made up of synthetic resin thus applicable to any
  • corrosion environment


  • Non-electronic type, long using life
  • Able to guarantee the electrical continuity and sustainability of function after repeated lightning strike
  • Different type of radius of protection are for users’ selection
  • Non electrical system will not be damaged by surge impact


  • High-rise buildings
  • Top of independent metal bar
  • Wireless communication base station
  • Warehouse of inflammable and explosive materials
  • Chemicals, radar station, oil deport, observatory, military base, mine field etc
  • Only self activate during lightning strike and initiatively intervene the lightning protection system
  • Good looking appearance, safe and reliable, no need of protection for lightning protection system, an art and decoration for buildings with function of defending direct lightning
