Digital Electronic Detonator - Chinaprice: contact company for price
1. Digital Electronic Detonator Initiation systemï¼š
Digital electronic detonator( EDD) consists of special logger, blasting machine and digital electronic detonator( EDD) , which can meet all kinds of complex blasting designs.
Logger is mainly used for the set and modification of EDD delay time, which can record 1600pcs EDD and test each branch.
Blasting machine is mainly used for the ignition of EDD with igniting power of 1600pcs EDD, which can verify the network ensuing the reliable blasting.
2. Three advantages of Digital Electronic Detonator:
( 1) . High accuracy: Mean variation and itâ€™s less than 0.2% in comparison with that 10% of the common delay detonator.
( 2) . High reliability: The EDD performance doesnâ€™t change under 70m water for 72hrs in comparison with that of common shock tube detonator 1m for 24hrs. The EDD misfire ratio is one millionth comparing with that of common detonator between one ten thousandth and one hundreds of thousandth.
( 3) . High safety: Anti- static and anti- ratio frequency.
3. Performance of Digital Electronic Detonator:
1) Delay time set and minimum delay interval: 1~10000ms ; 1ms
2) Delay Accuracy: Variation: less than 0.2%
3) Anti static: Leg- wire to leg- wire ( 20KV/ 2500PF/ 0.5Î©) discharge,
Leg- wire to shell ( 30KV/ 2500PF/ 0.5Î©) discharge, no ignition.
4) Water resistance: Immersed in saturated brine, 0.7 Mpa pressure, for 72hrs, performance doesnâ€™t change.
5) Tensile: 4KG weight drop and maintain the tension for 2min, 10KG tension for 10sec, performance doesnâ€™t change.
6) Flexibility: Under 50N, 90 Â° angle gravity, no fracture or damage to the shell.
7) Anti- drop: No explosion under 5m of free drop and led drop.
8) Impact Resistance: 2KG weight drop from 1200mm to the plain cap and ignition part, no explosion.
9) Resistance to rf, stray current: No initiation connected with 80MHz- 2GHz, 10V/ m, 250mA, stray current.
10) Anti- temperature: In 100â„ƒ for 4 hrs, no explosion.
11) Usage / Storage temperature : - 20â„ƒï½ž+71â„ƒ/ - 40â„ƒï½ž+71â„ƒ
12) Network test: Test and verify in two way communication, make sure no problem, and blast successfully.
13) Network capacity: Each blasting machine connects no more than 1600pcs detonators; when over 1600pcs, use the synchronized blasting machine.
Can be used in multilayer ore mining blasting . accurate collapsed blasting in city center and water conservancy work.
