In order to achieve a low-density powder explosives line synchronization initiation, an exploding wire line initiation system was developed. Three low-inductance parallel capacitors were used in the energy storage device with a total capacity of 12 μF. A 1.5 kV pulse was employed to the primary of the trigger pulse transformer. The pulse transformer generated a 40 kV pulse to trigger the high-voltage switch. A 50 kV/100 kA high-voltage field distortion switch was developed. The system achieved a 73 kA pulse into the exploding wire. High-speed framing camera was used to obtain the image of the exploding wire explosion. The experimental results showed that the synchronization during the expanding process of the exploding wire was preferable. The line initiation system was successfully applied to explosion expanding ring experiment.
