Abstract
A cartridge having an electrothermal ignition device, in which, ignition conduits extend axially through a first propellant-charge powder ( ) filling a cartridge sleeve ( ), with the conduits essentially comprising an electrical wire ( ) that is guided axially through a tube ( ) comprising a second propellant-charge powder. Propellant-charge-powder tubes ( ) comprising an optically transparent propellant-charge powder are used so that even cartridges ( ) having a first propellant-charge powder ( ) that is difficult to ignite can be ignited rapidly and reliably, requiring the smallest possible quantity of electrical energy.
