DESCRIPTION

Digital Electronic Detonator: A high precision tool for complex mining operations and quarry blasting. The ability to program the blast delay with millisecond accuracy helps to effectively destroy the rock and reduce the possibility of earthquakes affecting nearby areas. Ideal for quarries, mines and construction projects.

EDD Initiation system

Digital electronic detonator( EDD) consists of special blasting machine and digital electronic detonator( EDD) , which can meet all kinds of complex blasting designs.

Blasting machine is mainly used for the set and modification of EDD delay time. It also has network detection function and initiation function for both single detonator blasting network. One blasting machine will initiate 4 0 0 pcs detonator at most. It will initiate more than 10000pcs detonators if they are connected into network.

Water  resistanceUnder normal temperature, immerse the electronic detonator in water with a pressure of (0.3±0.002) MPa for 4hrs. After being taken out,initiation performance does not change
Anti- temperature

In 85℃ for 4 hrs, no explosion.After taking out, detonate normally.

In -40℃ for 4 hrs, After taking out, detonate normally.

Anti- temperature and impact resistanceThe electronic detonator in -40℃for 3hrs and then in 85℃for 3hrs ,the temperature conversion time is 20s-30s , and the electronic detonator should not explode after three cycles .Aftertaking it out , at room temperature for 1h , and the electronic detonator can detonate normally.
TensileThe electronic detonator last for 1min under the static tension of 19 .6N , the wires and plugs connectors should not be damaged or moved visually , and the electronic detonator be able to detonate normally.
Anti  static

Leg-wire to leg-wire , leg-wire to shell(25KV/500PF/500Ω ) ,discharge no ignition

Leg-wire to leg-wire , leg-wire to shell(8KV/2000PF/0Ω ) , discharge no ignition

Anti-stray current100mA stray current is introduced into the bus, and the detonator and initiator communicate normally. Single detonator applied stray current of 250mA for 5min, without accidental detonation.
Resistance to RFRF energy with a power of 10w into the electronic detonator , and the electronic detonator should not explode in two modes:leg-wire to leg-wire and leg-wire to shell .
Anti-impactUnder the condition that the weight is (2.0 ±0.002) kg and the height is (0.8±0.01) n, the electronic detonator should not explode when it hits the head fuse and the charging part of the primary explosive respectively.
FlexibilityUnder 50N, 90 ° angle gravity, no fracture or damage to the shell
Anti- dropNo explosion under 5 m of free drop and led drop
Jolt test150mn high, 60Hz frequency, 10min vibration, no explosion and structural damage of detonator.
Network  testTest and verify in two-way communication, make sure no problem , and blast successfully
Network  capacitySingle blasting machine connects no more than 400pcs detonators;   When over 6000pcs, use the synchronized blasting machine
