Aluminium Electrical Detonators with 500 ms Delay Interval
It is a detonator having electrically ignitable fusehead by the action of dynamo type or condenser type exploder with delay time. They are used to blast dynamite and similar explosives at desired intervals and sequence to obtain a good and uniform fragmentation, the desired particle size, to decrease vibration and to increase the yield of the blasting in the great blasting operations. It can be manufactured at the desired cable length.
