    Shell length:50~70mm

    Leg wire: Galvanized steel, copper, copper clad steel

    Leg wire length: 2m~50m

    Igniter element: Elastic fuse head, rigid fuse head

    Variety: Common electric detonator, permissible electric detonator

    2. Performance:

    1) Resistance: Galvanized steel core Leg- wire ≤6.3Ω, with vibration ≤2.0Ω.

    2) Safety current: Charging with 0.2A constant direct current for 5mins, no explosion.

    3) Minimum firing current: ≤0.45A

    4) Firing impulse: 2.0~7.9A2· ms

    5) Series firing current : 20 pieces electric detonators are connected into series circuit, and charge with 1.2A electric current, and all detonators fire.

    6) Initiating Power: Have a lead plate test, piercing into 5mm lead plate, the hole diameter should no smaller than the out- diameter of the detonator.

    7) Tensible: Force on 19.6N static tension for 1 min, no damage to sealing plug and leg- wire.

    8) Anti- jolt property: Vibrate for 10min on the jolt machine, no explosion, structure damage, short circuit, open circuit and unstable performance occurs.

    9) Anti static: Legwire to shell discharge with 8kv voltage, 2000pf capacitance and 0Ω series resistor, no firing.

    10) Combustible gas safety degree: When initiating a permissible electric detonator in the combustible gas of 9% , the combustible gas should not be ignited.
