ROCKSTAR III 25/50 - Austin Detonator sro

ROCKSTAR III 25/50Highly Insensitive Instantaneous and Millisecond Delay Electric DetonatorElectricDESCRIPTIONElectric millisecond detonators ROCKSTAR III 25/50are designed to provide the precise control necessaryto produce accurate and consistent blasting results in avariety of blasting applications in the mining, quarryingand construction industries.ROCKSTAR III 25/50 detonators are fitted with a highlyinsensitive fusehead to bring extra safety to blastingoperations and makes the product especially suitablefor blasting in residential areas.BENEFITS• High initiation strength - 720 PETN / RDX base charge ensures reliable initiation of all cap sensitive explosives.• Industries strongest aluminum shell reduces the possibility of water hammer effect.• Antistatic PVC insulation for added protection from extraneous currents.• Wide selection of delay intervals provide greater flexibility in blast design.• Protected primary explosive charge.PROPERTIESDelay SequenceDelay #012345678910MS Nominal Delay0255075100125150175200225250Delay #1112131415161718192021MS Nominal Delay275300325350375400425450475500550Delay #222324252627282930MS Nominal Delay6006507007508008509009501000Resistances R max(Ω) Wire core | lenght (m) 2,02,53,03,54,05,06,09,012,015,020,025,030,0Cu 0,50,60,70,80,91,01,21,41,92,53,14,05,06,0Cu 0,60,50,50,60,70,70,91,01,41,82,22,93,64,2Fe 0,651,72,12,42,83,13,84,56,88,911,114,618,421,9Maximum values are stated.
