Electric caps ED-Z-N | ED-VM1

When carrying out blasting operations in conditions where there is no danger of accumulation of static electricity charges and occurrence of ground currents, ED-Z-N electric caps with a safe current of 200 mA and a safe pulse of 0.6 A2·ms and normal sensitivity to static electricity discharges are used.
ED-Z-N is a nonfuse electric detonator with deceleration, normal sensitivity to ground currents, and charges of static electricity.
ED-8M1 is an instantaneous electric cap used instead of the “0” series of the ED-Z-N cap.

On the ground as well as in mines and mine pits without dangerous gas or dust and in shale mines with dangerous dust, in conditions that are not dangerous as regards charges of static electricity and ground currents.
