Exel™ U Det
Exel™ U Det is a non-electric initiation system developed to give the greatest possible simplicity, in both use and storage.
The system is based on a combination of in-hole detonators and surface connector units. All drill holes in the round are charged with detonators that have the same delay time. The initiation sequence is then determined on the surface by means of delays in the surface connector units. Owing to the uniform delay in the in-hole detonators, there is time enough to initiate all drill holes before any rock movement begins.
To meet the varying demands on delay times for different kinds of blast, there are:
· 6 different uniform delays for in-hole detonators (U 400 – U 1000), which are fitted with red Exel™ tube (see table). Yellow colour can be supplied to special order.
· 7 different delays for the surface connector units.
(See TDS for Exel™ Connectadet™ SL for more information.).
Exel™ U Det detonators are designed to provide hole-by-hole initiation sequences in blasting situations where a constant in-hole delay is required. The in-hole detonator will directly initiate cap sensitive boosters and packaged explosives. Refer to the relevant Technical Data Sheets for details.
