EXTERNAL LIGHTNING PROTECTION HELIA ESE LIGHTNING TERMINAL ODTU METU GENERAL DESCRIPTIONS HELIA Early Streamer Emission (ESE) lightning terminal can anticipate all other elements and items within its protectable range according to its protection level radius by intercepting the lightning strikes and conducting these strikes into the earth through the safest and projected ways. HELIA ESE Terminal work as to principle of creating IONs by its internal ION GENERATION channels. This structure itself allows the terminal to conduct the high voltage lightning strikes, even up to 200kA, to the earthing system then to the earth at the safest way. HELIA ESE Lightning Terminal is exclusively suitable to install for high-rise buildings, airports, naval bases, open areas, critical military zones, stadiums and highways. Tested and certified according to NFC 17102/2011 Early Streamer Emission Standard including DeltaT (AT) advance time test, current withstanding test to determine HELIA's protection levels. > High Salt mist treatment > Humid sulphurous atmosphere treatment > Current withstanding test: 200kA (10/350ps). > Advance time DeltaT (AT) test
