Performances:

type	Resistance between two legwire(Ω)	Resistance of legwire and tube(Ω)	Firing current(A)	Safety current(A)	Resistance to temperature
DT-Y100	51	≥1000	0.8	0.2 during 3s	190,100MPa, 1h.
DT-2Y100					218,100MPa, 1h.
DT-3Y100A	56				163,100MPa, 1h.
DT-3Y100B					218,100MPa, 1h.

Antistatic property: A 5KΩresistance connected in series with a 500pF capacitor, voltage 25KV, discharge to the legwire and tube of the detonator, it is not allowed to fire.

Initiating property: it is reliable to initiate detonating cord lead wrapped and detonating cord used in oil field.

Note: take care in handling, prohibit to be impacted and fractionated, away from fire and heat source, moisture preventing. The resistant should be tested in a protector before using and the testing current is less than 0.01A.

Storage: to be stored in a ventilating and dry storehouse under the original package condition.

Shelf-life: 3 years.

Packing: outside: carton

               inside: paper box
