Seismic Instantaneous Electric Detonators are supplied in No.8 strength with 23 SWG Copper lead wires.
Seismic Instantaneous Electric Detonators Consist
of an Aluminum tube closed at one end and to the other end are attached the lead wires. These detonators have a specially developed fusehead
designed to go off within one milli-second of the current application. The fuse head is protected by a special anti-static sleeve.
Seismic Instantaneous Electric Detonators being fast action detonators, are Capable of with standing high hydrostatic pressure, meets the critical
needs for seismic prospecting and therefore is specially developed for Seismic exploration on land or offshore.
