Seismic Protecting Electric Detonator

Detailed Product Description

 

Uses: It 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
