Super Electric Milli Second Delay Detonators

Super Electric Milli Second Delay Detonators (Sdd)

Short Delay Detonators have delay numbers ranging from zero to ten (0 - 10) with a nominal time interval of 25 milliseconds between successive delay numbers from 1 - 6, 50 milliseconds for 7 - 8, 75 milliseconds for 9 - 10. Delay numbers 0 - 10 are identified with number tag on the leg wire. Fuse Heads are fitted to the shells. Precise consistency of the unique design of the Fuse Head is maintained by a fully automated process and strict quality control:

Packing:

The Detonators are bound in bundles of 25 each. Such bundles (25Nos.) are Packed in wrapper (parcel) Forty of these parcels (containing totally 1,000 detonators of 3 meters wire) are packed in a Fibre Board case. Depending on the length of leg wire requisite number of packets are packed in fibre case inside with water- proof paper. Case marking provide for indicating wire length, type of wire and delay number. Higher lengths of leg wire are supplied at customers requirement.

Applications:

Short Delay Detonators are designed for use in opencast and underground metal mines, driving tunnels, drifts and shaft sinking and in quarries where multi-shot rounds are required to be fired.
