MEGADET®

MEGADET® detonators are a series of high strength non-electric detonators with millisecond delay intervals ranging from 0 ms (instantaneous) to 1000 ms.

MEGADET® detonators consist of a non-electric detonator, a length of shock tube, and a plastic J clip connector. The detonator incorporates delay elements, primary explosive, and a high strength PETN base charge inside an aluminium shell.

The shock tube is high strength, high abrasion resistant tubing which transmits the initiation signal to the detonator. One end of the shock tube is crimped and sealed into the detonator shell and the other end is closed off by a waterproof seal and fitted with a plastic J clip. The plastic J clip provides a rapid and secure means of attaching the shock tube to the detonating cord.

APPLICATION

MEGADET® detonators are designed for use as an in-hole initiating system for all blasting applications. MEGADET® detonators are
commonly used for initiation of cast boosters and cap sensitive cartridged explosives products.
