TERMINAL Technical Data:  According to standards NFC 17-102,UNE 21186  Electronic circuit, high voltage impulse emitter and upward streamer generator. Working threshold below 50 kV/m potential gradient between atmosphere and ground. This circuit is watertight, located in the central body of the air terminal housing against electric discharges by Faraday cage shaped assembly.  Triple insulating system protector, which warranties the system performance in all weather conditions.  Stepped electrostatic charge accumulator and a single discharging tip in order to avoid the ineffective charge spread.  Housing made of stainless steel (AISI-316) (without aluminum parts to avoid the formation of galvanic pairs and corrosion).  Atmospheric electric charge as its only power supply, being self-autonomy and maintenance free.
