Lightning Protection

dinnteco 100plus

Lightning rod with “stop lightning strikes from occurring” mechanism

While traditional lightning-rod system works as “conduct and drop lightning down”,our dinnteco-100plus is an entirely new lightning rod with the ability to “suppress” lightning occurrence.
This has solved the major problem facing the traditional lightning rods: lightning surges (electrical and electronic damage caused when huge currents pass through the lighting rod) caused by direct lightning strike.
The latest and best solution for lightning damage,whose costs and losses are now estimated to be over 1 trillion JPY per year.

■Communication tower in Masella, Spain (Demonstration test period:1 year 7months)

Lightning struck zero times atMasella communication tower, in area with high frequency of lightning!

dinnteco-100plus was installed at the Masella communication tower owned by ABERTIS TELECOM in Spain. Previously, lightning that damaged the electric and electronic parts struck often. After dinnteco-100plus was installed, there were 374 lightning strikes within a 3km area, but zero strikes within the protection range (100m radius).

Distance drom device No. of lightning srikes
0m (direct lightning strike) 0 strikes
within 100m 0 strikes
100m or more, less than 300m 11 strikes
300m or more, less than 500m 8 strikes
500m or more, less than 900m 50 strikes

■Weather radar from Biscay, Basque Country, Spain (Demonstration interval: 2 years)

Spanish State Meteorological Agency radar protected from winter lightning

dinnteco-100plus was installed for the Spanish State Meteorological Agency weather radar. Basque Country is known as having a high lightning rate. The radar had been directly struck by lightening before dinnteco-100plus was installed. Even during the demonstration, there were 96 strikes within a 2km radius, but there were zero cases of lightning strikes, including winter lightning, within the protection range.

Distance drom device No. of lightning srikes
0m (direct lightning strike) 0 strikes
within 100m 0 strikes
