Detonating cord (also called detonation cord, detacord, det. With the PETN exploding at a rate of approximately 6400 m/s, any common length of detonation cord appears to explode instantaneously. It is a high-speed fuse which explodes, rather than burns, and is suitable for detonating high explosives.
Correspondingly, how does a detonator work?
An electrical detonator fuse, called a lead line, is just a long length of electrical wire. At the detonator end, the wire is surrounded by a layer of explosive material. This heat ignites the flammable substance on the detonator end, which in turn sets off the primer charge, which triggers the main explosives.
Beside above, when was det cord invented? 1908

What is an explosive primer?
…of the delay is the primer, an explosive (generally lead azide, mercury fulminate, or pentaerythritol tetranitrate [PETN]) that, upon detonation, releases a great deal of energy in a very short time. This is sufficient to ignite the larger amount of ANFO explosive packed into the hole.
