LIGHTNING FORMATION
Facts about Lightning • A strike can average 100 million volts of electricity • Current of up to 200,000 amperes • Can generate 54,000 oF • 10/350MicroSec/50KA Fault Current/Discharge in Nano Sec Protection Earthing Design100KA Fault Current/Joints Exothermic /Flexible Down Conductor with Shortest Route & Less Corner
