ese copper early streamer emission lightning rod
SEL series lightning rod is a kind of product, which matches GH
model ring type steel lightning rod and ZG model ring type
reinforced concrete lightning rod
Lightning rod Operating principle
1. When cumulus-nimbus cloud is created , between the earth and
cloud there will be produced the electric field , and the strength
of the electric field will close to 5 kV/m whereas the various high
points such as the protrusion and metal parts will create natural
2. Several tracers are produced at the core of the cloud and they
travel to the ground by successive steps . When these descending
leaders come closer, the ionization of the high points increases
and produces ascending tracers.
3. The meeting of the two tracers creates an ionized path down
which the cloud discharges its electric charge . The buildings on
the earth will create lots of ascending tracer and the first
ascending tracer which meets with the descending tracer determines
the place of the lightning poin.
