Modular Standard Electronic Detonator Initiating System

The modular standard electronic detonator consists of two parts: the electronic plain detonator and the blasting leg wire with a built-in capacitor. During use, they are assembled through a quick and simple connector, secured with a fastening nut.

This product is suitable for high-precision blasting in environments without the risk of combustible gas or mine dust explosions, such as non-coal mines, shaft tunneling, and tunnel excavation.

Key Benefits

Superior anti-static, anti-stray current, and anti-radio frequency performance. IoT intelligent control with key authorization detonation. The product does not contain sensitive igniter compositions, making it safer to ship, store, and use. It also offers enhanced resistance to vibration and impact during operation.

The leg wires and detonator body are stored separately, reducing the space required for packaging and making storage more convenient. The leg wire length of the single electric plain detonator can be adjusted as needed, providing users with greater flexibility.

The product does not contain a fusehead, making it more environmentally friendly.

Technical Properties

Testing Items	Technical Properties
Delay Time	6,000 ms, with a minimum programmable interval of 1 ms
Delay Accuracy	0-150 ms delay, accuracy deviation ≤±1.5 ms; >150 ms delay, accuracy deviation ≤±1%
Leg Wire Tensile Strength	Under 20 kg (196N) static tension, the wire core and insulation layer should not break, damage, or short circuit.
Leg Wire Tensile Strength	With a 700 g weight vertically applied to the insulation layer, and sandpaper in between, the insulation layer could not short-circuit after abrasion distance ≥150 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 10 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 24 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 -20°C (-4°F) to 55°C (131°F).
Leg Wire Resistance	≤0.6 ohm/m
Initiation Capacity	Capable of penetrating a 5 mm thick lead plate, with a hole diameter of at least 9 mm.
Maximum Load per Detonator	Each standard detonator can support up to 500 detonations
Shelf Life	2 years
