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.
