SXFJ-180612 Lightning Stroke System for Direct Current Test on Aircraft

(model SXFJ-180612)

The aircraft is easy to be attacked by the direct lightning when it flies in the convective environment, which will generate high temperature, high pressure and strong electromagnetic force. This will cause some bad affection to the aircraft, such as burn, explosion, structural aberration, etc. The lightning stroke system for direct current test on aircraft (model SXFJ-180612) is developed by our company and can simulate the direct lightning stoke with component A,B,C,D waveforms. It includes four sets impulse current test systems.
