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 List of packing number External dimensions of carton Gross weight(kg) Pieces/carton Pieces/box 390*340*240 10 1 50
