ED-1-Z-T are non-protective electric detonators of low sensitivity to stray current and charge of static electricity. They are designed for initiating explosive charges while blasting works on the surface, and also in mines and pits which are not dangerous for gas and dust in shale mines, which are dangerous for dust. ED-1 -Z-T are similar to the ED-Z-N in design and material. Differs that has other fuse head in the electric spark igniter. ED-1-Z-T have 36 series of delay.

   Identification of series of delay is made by marking of the label or tag fixed on the lead wires. The lead wire length is 2,5 and 4,0 m. The length of lead wire under of consumer can be anyone. Material of the thread - copper, its 0is 0,5 or 0,6 mm. Material of the shell - steel with tombac coating. They are delivered in boxes in the size: 546x507x346 mm. There are 1008 electric detonators with the lead wire length 2,5 m or 630 electric detonators with the lead wire length 4 m in one box. Number of UN 0030, Classification code 1.1 В Sources of continious and alternating current, blasting devices and machines can be used for injury electric detonators.
