Electric detonators
Explosives Manufacturing Industries markets special designed electric detonatorsallowing highly accurate and reliable explosions.
- Correct use of delays contributes significantly to increasing the rock crushing and allows good control of ground shocks.
- The detonator’s body is made of aluminum and contains a basic load of 0.8 gr P.E.T.N., which ensures good initiation of all types of explosives defined as sensitive to activation by a detonator.
- The detonator’s extension cords are made of copper 0.51 mm and 0.70 mm diameter.
- They are coated with an isolating material ensuring also good wear resistance.
- The detonators are backed in cardboard boxes.
- The detonators are waterproof and protected against static electricity.
- On the detonator extension cords, there is a flag with the delay number. Each delay has a different color flag.
Delay 0 = immediate detonator.
Benefits
- Ensures better crushing of the rock.
- The delay accuracy allows flexibility in planning the explosion and control over the shock level.
- High resistance to water penetration (good waterproof).
- Reliable activation of any mixture sensitive to a detonator
- Good protection against static electrostatic discharge thanks to the protection on the match head.
- High shelf life.

PROPERTieS
- Overall behavior involves the resistance of the match head, which is (51.0+9) screw-nut and the extension cords’ resistance.
- In detonators with conductors up to 10 m in length, the extension cords are folded in the form of the number 8.
- In detonators with conductors longer than 10 m, the extension cords are wrapped on coils.
