Foresight and efficient protectionAn Early Streamer Emission Lightning Conductor in characterized by its reaction to the lightning aproach, being the first one to capture it in its radius of action, to conduct it to the ground in a safe way. Immediate reaction. The standard name is "time in advance" (t) It determines the radius of protection of the air terminal and must be tested and certified by official and therefore independent laboratories. Maximal resistance, non perishableIt is essential for these tests to be preceded by lightning current withstanding tests, with the aim of proving that the air terminal is not perishable and keeps working even after several lightning discharges. Performance under rain On the top of that, an air terminal must mantain its performance in all types of weather conditions because rain could short-circuit it and make it lose its effectiveness. Independence and reliabilityIn order to offer a better guaranty for the end user, the air terminals Dat Controler® Plus are submitted to tests performed by official independent laboratories and they have gained the AENOR product quality seal of certification.
