Exel™ LP detonators are a series of full strength non electric detonators with long period (LP) delay intervals between successive firing times. Exel™ LP detonator assemblies consist of a non-electric detonator and a length of yellow Exel™ signal tube. The detonator incorporates delay elements and >EU#3 strength base charge inside an aluminium shell. The 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.
Exel™ LP detonators provide a series of delay times suitable for development blasting in underground mining and for civil tunnelling.
Exel™ LP detonators will directly initiate cap sensitive boosters and packaged explosives. Refer to the relevant Technical Data Sheets for details.
