Product introduction

 The transmission lion MOA are the major protective apparatus used foe preventing transmission line from being strck by lightning.Some of the tranmission lines for a.c. system are situated in the excessive-thunder area,where easy to be struck by lightning.When lightning strikes the top of tower,the tower arm's potential will arise.If the line insulation is exceeded,flashover occurs i.e. backflashover.When insulators damaged,the line short circuit to ground is happened.Then switch jumps off and power cut off.
