MRD series overvoltage protection device isadvanced protection equipment to limit lightning overvoltage and switchingovervoltage, applicable to 35KV and lower power system. It has quick action,flat volt-ampere characteristics, low residual voltage, stable performance andconvenient maintenance, thus play an effective protection to interphaseovervoltage and phase overvoltage.

It is applicable to 35KV and lower powersystem and is widely used to protect insulation of generator, transformer,switch, generatrix and motor from destroying.
