COPPER DELAY DETONATOR
This detonator is made of copper shells filled with PETN as the base charge mixed with a primary charge. The shells are crimped with a pair of PVC coated wires and are fitted to an electric fuse head.
Reliable means of delay initiation in underground coal mines, which provides required free face for successive rows of holes in solid blasting
Always keep the ends of wires shunted and open just prior to connections. Disconnect the firing cable from the exploder if circuit requires rechecking.
Delay Detonators contain sensitive components and must be handled with care at all times. While using, the total circuit resistance to be monitored to ensure recommended in flow of current.
