Millisecond Electric Detonator, MSED - Al/Cu


Usage

Millisecond Electric Detonators are aluminum or copper detonators which can be initiated with electricity. They are used for firing the cap sensitive explosives at desired intervals and sequence, to obtain a good uniform fragmentation, the desired partical size, to decrease vibration and to increase the yield of the blasting in the great blasting operation. They are used in environment which doesn't contain firedamp and other dangerous gases in.

Half - Second (aluminum or copper) Electric Detonator, PSED - Al & PSED - Cu
Usage

Half Second (Aluminum or Copper) Electrical Detonators are used for mining of middle hard and soft materials. Because of the long delay intervals it comes to successive results with larger granulation, suitable for transport, the shakes are minimized to the power of one mine. For getting of the smaller granulation it is recommended the usage of quarter second detonators in combination with half second. They are used in the environment which does not contain firedamp and other dangerous gases in.
