ISKRA-Sh Non-electric initiating System
 |
ISKRA-Sh system is sensitive to initiating impulse from ISKRA-P detonating cap, detonating cords and electric detonator. ISKRA-Sh detonating cap initiates 6ZhV ammonite cartridges and boosters. ISKRA-Sh shock tube is 2, 4, 7, 10 or 16 m, as per customer demand. Devices packed by 5 to 20 pieces are laid in plastic bags and shipped in boxes. One box fits 240 devices. UN number: 0360. Classification code: 1.1 B.
