The exploding-bridgewire detonator (EBW, also known as exploding wire detonator) is a type of detonator used to initiate the detonation reaction in explosive materials, similar to a blasting cap because it is fired using an electric current. EBWs use a different physical mechanism than blasting caps, using more electricity delivered much more ...
In 1875, Smith—and then in 1887, Perry G. Gardner of North Adams, Massachusetts—developed electric detonators that combined a hot wire detonator with mercury fulminate explosive. [13] [14] [15] These were the first generally modern type blasting caps. Modern caps use different explosives and separate primary and secondary explosive charges ...
The exploding wire method or EWM is a way to generate plasma that consists of sending a strong enough pulse of electric current through a thin wire of some electrically conductive material. The resistive heating vaporizes the wire, and an electric arc through that vapor creates an explosive shockwave .
As a transmission medium, it can act as a downline between the initiator (usually a trigger) and the blast area, and as a trunkline connecting several different explosive charges. As a timing mechanism, detonation cord detonates at a very reliable rate (about 6,000–7,000 m/s or 23,000–26,000 ft/s), enabling engineers to control the pattern ...
Nonel shock tubes (pink, red, orange, yellow) with Orica surface delay connector (blue) in use. Nonel is a shock tube detonator designed to initiate explosions, generally for the purpose of demolition of buildings and for use in the blasting of rock in mines and quarries.
“You have one tube up one leg of your pants that has the blood to your chest, and you have a wire running down the other leg. This guy is out in the bushes with a detonator to set the blast off ...
The supposed effectiveness of IED jamming systems, including vehicle- and personally-mounted systems, has caused IED technology to essentially regress to command-wire detonation methods. [citation needed] These are physical connections between the detonator and explosive device and cannot be jammed. However, these types of IEDs are more ...
