We are studying the experimental behavior of non-refractory and refractory wires in the 1 kJ pulsed electrical system. This article discusses the experimental study of non-refractory (copper-nickel) and refractory (tungsten) explosive wires in pulsed electric discharge systems. The system energy is 1 kJ, the wire length is 4 cm, and its diameter is 200 μm. To study the behavior of the wires, the electrical parameters of current and voltage of electric discharge and shock waves have been investigated. In non-refractory wires, the current is periodic and has two peaks. In refractory wires, two current peaks are formed at a longer time interval. This shows that the energy level of 1 kJ was not enough to change the state and create plasma in this sample of wires. Finally, under the current test conditions and comparison of the experimental results, it can be seen that the non-refractory wires create a more substantial shock wave than the refractory samples. This pressure is 8.5 MPa in non-refractory wire (copper-nickel) and 6 MPa in refractory wire (tungsten). Also, we compared the electrical discharge current for three copper-nickel wires with diameters of 100, 200, and 300 micrometers and experimentally observed that the electrical discharge current is higher in the wire with a thicker diameter.
