Exel™ Long Period Detonators
Exel™ Long Period Detonators are a series of high strength non-electric detonators with Long Period (LP) delay intervals between successive firing times.
Exel™ LP Detonators consist of a non-electric detonator, a length of Exel™ signal tube. A plastic J-hook connector can be enclosed at the sealing end of the signal tube as per customer requirement. The detonator incorporates delay elements and a high strength PETN base charge inside an aluminium shell. The yellow Exel™ signal tube is a high strength, high abrasion resistant tubing which transmits the initiation signal to the detonator. One end of the signal tube is crimped into the detonator shell, and the other end is closed off by a waterproof seal. The plastic J-hook provides a rapid and secure means of attaching the signal tube to detonating cord. It is colour coded and has the detonator delay and time printed on it.
Exel™ LP Detonators are factory assembled and auto-coiled into circular coils and marked accordingly.
