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 ...
Types of detonators include non-electric and electric. Non-electric detonators are typically stab or pyrotechnic while electric are typically "hot wire" (low voltage), exploding bridge wire (high voltage) or explosive foil (very high voltage). [2] [3] The original electric detonators invented in 1875 independently by Julius Smith and Perry ...
EWM has found its most common use as a detonator, named the exploding-bridgewire detonator, for nuclear bombs. Bridgewire detonators are advantageous over chemical fuzes as the explosion is consistent and occurs only a few microseconds after the current is applied, with variation of only a few tens of nanoseconds from detonator to detonator.

They provide the explosives used in coal and metal mining, quarry and construction as well as pipeline and seismic used for oil and gas exploration. [5] The types of explosives manufactured includes ammonium nitrate , dynamite , electric, non electric and electronic detonators , detonating cord and cast boosters .
Setting off the NASA standard detonator, which itself activates other systems explosively. Triggering Pyrotechnic Circuit Interrupters, severing bundles of electrical cables. Triggering explosive valves to open/close pressurization lines or fuel lines. Triggering a pyrotechnic pin puller which opens a Marman clamp, separating two spacecraft.
A common chemical used for explosives was discovered in a Texas storage locker linked to the U.S. Army veteran who killed 14 people and injured more than two-dozen when he plowed into New Year’s ...
(A) Slapper detonator's pellet or flyer impacts a wider area of surface on the explosive output charge, and even though energy is lost to the sides of the area impacted, a cone of explosive is efficiently compressed. (B) EBW detonators only initiate a single point, and energy is lost in all directions, making the energy transfer less efficient.
A robot attacked a Tesla worker and left them bleeding on the automaker’s Austin factory floor two years ago, according to an explosive new report. It was one of a series of incidents at Giga ...
