DESCRIPTION
Magnetic detonators: designed to operate in high electromagnetic environments, such as mines or industrial areas with high electrical noise. Safe to use due to their immunity to stray currents and electromagnetic interference. Used in mining, construction and blasting industries.
PERFORMANCE
Item | Performance |
Anti direct current | 30A |
Anti direct current voltage | 300V |
Anti power frequency voltage | 380V |
Safety frequency | No explosion charging with 10A current between 0～2KHz,300KHz~ ∝ for 1min |
Safety current | Under rated work frequency, no explosion charging with 0.4A effective current for 5min |
Series firing current | 20 pieces of detonator connected into series circuit with 3.0A constant current, all explode |
Static Sensitivity | 2000pF, 15KV, discharging the magnetic ring-shell, no explosion |
Water Resistance | Immersed in 20m deep water for 20hrs, initiation performance does not change |
Jolt test | No explosion, structural damage, shortcut or open circuit after vibrating for 10 minutes in the vibration machine |
Initiating capacity | Have a lead plate test(5mm), after initiation, the diameter of the hole should not be smaller than the detonator OD |
