electrical firing
Quick Summary
Electrical firing in industrial processes, particularly in blasting, offers significant advantages over traditional fuse methods. It allows for precise timing of detonations, the simultaneous firing of multiple charges, and superior water resistance.1
The development of electric blasting caps began in the 1700s, but practical designs emerged in the late 19th century. Modern electric blasting caps typically use a high-resistance wire embedded in an ignition mixture. This wire heats up when an electric current is applied, initiating the explosive charge. Materials like PETN and RDX are common explosives used in these caps, offering strength and safety.1
Detonating cords, which contain high explosives, can also be initiated by electric blasting caps. These cords are used to connect multiple blasting charges in various patterns, enabling controlled explosions for industrial applications.2
