NSI «PULSAR»
PULSAR non-electrical system of initiation. TU 20.51.12-021-43918744-2024
The PULSAR NSI is designed to conduct blasting operations on the ground and in underground workings that are not dangerous for gas and/or coal (shale) dust at ambient temperatures of minus 500С to plus 650С.
NSI "PULSAR" is used for initiating detonator checkers, emulsion cartridges sensitive to the cap, ammonite 6GV cartridges or other industrial explosives approved by Rostekhnadzor, as well as for initiating the explosive chain.
Depending on the detonator capsule used and the waveguide length, NSI PULSAR include:
- NSI "PULSAR" SK – detonator capsules with deceleration in the range 0 – 900 ms, are designed for initiating charges during explosion work on the ground surface, according to the conditions of use belongs to products based on explosives class "Special" (C), group 1;
- NSI "PULSAR" SD - Capsule-detonators with deceleration in the range 0-8000 ms, are designed for initiating charges during mining operations in underground workings, not dangerous for gas and/or coal (shale) dust, according to the conditions of use belongs to products based on explosives class "Special" (C), group 2;
- NSI "PULSAR" P – microcapsule in the group connector with a response time of 0 to 200 ms; are designed for installation of explosive networks during explosion work on the ground surface, according to the conditions of use belongs to products based on explosives class "Special" (C), group 1.
