The protective electric detonators short delay operation ED-K-Z-PKM are normally sensitive to the effect of static electricity charges and wandering currents. They are designed for initiating explosive charges in mines which are dangerous for gas and dust. The ED-KZ-PKM electric detonators have 10 series of delay. Identification of series of delay is made by marking of the label fixed on the lead wires. The lead wire length is 2,5 and 4,0 m. The length of lead wire of the consumer can be anyone. Material of the thread: copper, its 0 is 0,5 or 0,6 mm.

   The shell is made of steel with tombac coating. The shell is coated by the flame arresting composition. They are delivered in boxes in the size546x507x346 mm. There are 882 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 1.1B. Sources of continious and alternating current, blasting devices and machines can be used for injury electric detonators.
