DESCRIPTION
Industrial Electric Detonators: Designed for a wide range of applications in industrial blasting, including building demolition, quarrying and mining. High reliability and safety make them suitable for a variety of blasting applications requiring precise timing and high power.
Product Details
| Item | Performance |
| Resistance | Galvanized steel core Leg-wire ≤3.9Ω, with range ≤1.0Ω |
| Safety current | Charging with 0.2A constant direct current for 5mins, no explosion |
| Minimum firing current | ≤0.45A |
| Firing impulse | ≥2.0A2 ·ms |
| Series firing current | 20 pieces electric detonators are connected into series circuit, and charge with 1.2A electric current, and all detonators fire. |
| Initiating Power | Have a lead plate test, piercing into 5mm lead plate, the hole diameter should no smaller than the out-diameter of the detonator |
| Tensile property | Pull with 19.6N static tension for 1 min, no damage to sealing plug and leg-wire. |
| Jolt test | Vibrate for 10min on the jolt machine, no explosion, structure damage, short circuit, open circuit and unstable performance occurs. |
| Anti static | Legwire to shell discharge with 8kv voltage, 2000pf capacitance and 0Ω series resistor, no firing. |
| Combustible gas safety degree | When initiating a permissible electric detonator in the combustible gas of 9%, the combustible gas should not be ignited. |
