Initiating Systems

Enhanced Electronic Detonator Initiating System

This system is designed for extreme conditions, including deep-hole onsite mixing in extremely cold (-40°C to -20°C, -40°F to -4°F) or high-temperature (55°C to 85°C, 131°F to 185°F) environments, and other blasting projects that require high resistance to water, abrasion, and tension.

In addition to standard blasting applications, it is particularly suited for challenging conditions such as high-temperature and extreme cold environments, deep-hole surface blasting, large underground blasts with upward holes, and deep-water blasting.

Key Benefits

Superior anti-static, anti-stray current, and anti-radio frequency performance. IoT intelligent control with key authorization detonation.

The blasting network is detectable, and compared to standard electronic detonators, it offers significantly enhanced performance in temperature resistance, tensile strength, water resistance, abrasion resistance, and bending resistance.

Technical Properties

Testing Items	Technical Properties
Delay Time	16,000 ms
Programmability	Options for 12,000 ms or 16,000 ms, with a minimum delay interval of 1 ms.
Delay Accuracy	0-300 ms delay, accuracy deviation ≤±1.5 ms; >300 ms delay, accuracy deviation ≤±0.5%
Leg Wire Tensile Strength	Under 40 kg (392N) static tension, the wire core and insulation layer should not break, damage, or short circuit.
Leg Wire Abrasion Strength	With a 2,700 g weight vertically applied to the insulation layer, and sandpaper in between, the insulation layer could not short-circuit after abrasion distance ≥300 mm.
Anti-Knock Property	The detonator is subjected to a jolt tester with a cam speed of (60±1) r/min and a drop height of (150±2) mm for 15 minutes. During the test, the detonator could not explode, loosen, or suffer damage. After the test, the detonator could function normally.
Anti-Static Performance	The detonator does not explode when its leg wires are discharged at 25 kilovolts using a 500 picofarad capacitor and a 5,000 ohm series resistor.
Water Resistance	The detonator could function normally after being submerged at 0.3 MPa water pressure for 72 hours.
Leg Wire Bending Resistance	The leg wires could maintain normal conductivity without breaking or cracking after being bent 10 times in an environment ranging from -40°C (-40°F) to 85°C (185°F).
High and Low Temperature Resistance	All performance metrics meet the standards, and the detonator functions normally in operating environments ranging from -40°C (-40°F) to 85°C (185°F).
Leg Wire Resistance	≤0.4 ohm/m
Base Charge	RDX: 800 mg; Initiating explosive: 300 mg
Initiation Capacity	Capable of penetrating a 5 mm thick lead plate, with a hole diameter of at least 10 mm.
Shelf Life	2 years
