Сейсмическая Защита электродетонатора (огонь cracke

Uses: Seismic detoantor(fire cracker) can be used for detonating vibrating sources which produce seismic waves, finding out geological structure, the distribution condition of petroleum and mineral resources. Main Parameters: Initiating power Tube material Core material Tube length(mm): Core diameter(mm) Legwire length(m) No8 Copper; Steel Copper 50 0.45;0.5 2(or on requirement of users)Performance: Resistance (Ω): Core diameter 0.45mm, 1.7-2.7Ω.Core diameter 0.5mm,1.5-2.5Ω Safety current: when apply 0.18Aconstant DC to the detonator, it is not allowed to fire during 5mins. The ignition current of a single detonator: 3.5A Effect time:1ms. Antistatic property: A5KΩresistor connected in series with a 500pF capacitor, voltage25KV.Discharge to the legwire and tube of the detonator, it is not allowed to fire. Water proof: Immersed in water of 30m deep for 72hours, the initiating power should not be changed. Note: Take care in handling, prohibit to be impacted and frictionated, away from fire and heat source, moisture preventing. The resistant should be tested in a protector before using and the testing current is less than 0.03A Storage: To be stored in a ventilating and dry storehouse under the original package condition.Shelf-life:2years.Packing: Outside: wooden box Inside: carton List of packing Legwire length(m) 3 7 8 10 15 25 External dimensions of wooden box(mm) 605*320*315 605*320*315 540*475*225 615*295*300 Gross weight(kg) 25 Numbers Legwire length(m) 3 5 6 8 10 15 25 Legwire diameter(mm) Pcs/carton Pcs/box Pcs/carton Pcs/box Pcs/carton Pcs/box Pcs/carton Pcs/box Pcs/carton Pcs/box 0.45 100 1000 80 800 50 500 10 200 10 150 0.5 70 700 50 500 10 2000 10 150
