Triggers and Blasting Assemblies

JSC "Novosibirsk Mechanical Plant "iskra" produces triggers for initiating shock tubes and blasting assemblies for initiating electric detonators.


  1. Simplicity in use.
  2. Reliability.
  3. Compact size.
  4. Best value for money.
  • It is designed for initiating of shock tubes and shock-tube-based devices like non-electric detonators ISKRA, as well as other devices of the same kind, during surface blasting works and underground blasting in gas- and dust-safe mines.
  • UPU is designed for initiating shock tube of non-electric detonators ISKRA or electric detonators individually or in a group in series connection blasting circuit (normal and reduced sensitivity up to 10 pcs., low sensitivity up to 5 pcs.) as well as for initiating other analogous products during surface and gas- or dust-safe underground blasting.

  • It is designed for emission of current impulse of a given magnitude in order to initiate electric detonators of normal and low sensitivity individually or in a group (in a series and series-parallel connection of the blasting circuit) and for measuring resistance of blasting circuit when carrying out blasting works in gas- and dust-safe mines and pits and surface works, in construction, civil engineering (welding and metal working by blasting) and laboratory testing.
