Ebw detonator pdf printer

The EBW and the slapper detonator are the safest known types of detonators, as only a very high-current fast-rise pulse can successfully detoonator them. Low- impedance capacitors and low-impedance coaxial cables are required to vetonator the necessary current rise rate. bridgewire detonator. 1. Introduction Fundamental to determining the initiation mechanism of an EBW detonator is an understanding of the processes by which the plasma, generated by the bridgewire explosion, interacts with the explosive to establish a detonation wave. However, this is a complicated phenomenon and must therefore be split Core Lab welcomes Guardian Global Technologies as part of the Core Lab Team! Click here to learn about Guardian and their complementary next generation Production Enhancement technologies. The EFI and EBW detonators used in this study were both based on a common design. The detonator body was a cylindrical can. For the exploding foil detonators a backing plate was placed over one end and the PETN pressed into the can to the required density. The backing plate was then removed and The detonator simulator has bridgewire resistance, pin spacing, explosive train, and heat sink properties identical to those of the EBW detonator and was designed specifically for these tests, since actual EBW detonators could not be used. The functional charac-teristics of the protective spark gap in the detonator, The EFI is an improvement over the similar Exploding Bridge Wire (EBW) detonator with more efficient detonation transfer, lower voltage initiation, increased safety, and the ability to initiate a greater variety of insensitive explosives. A hiqh-temperature resistant explodinq bridgewire detonator is described. The explosive is ETX, which shows no exotherm below the melting. point. 263"C, and is stable in vacuun stability tests at a temperature exposure of at least l~s"c for 90 dhYs. The enerqy re-quired is hiqher than is used for PETN detonators. Design studies are being made.

The RP explosive is contained in a " thick stainless steel case which is crimped onto the plastic head. OPEN ACCESS. A view MIL-STD-1316D the basic S&A safety guide requires in-line detonators to be qualified in accordance with MIL-I-23659, yet 23659 was based primarily on qualifying hot bridge wire de-vices and is poor to qualify the in-line detonator of choice the Exploding Foil Initiator (EFI). The report proposes changes to 23659 to qualify EFI's and EBW's. simulation. Three types of exploding bridge wire (EBW) detonators, provided by RISI, were investigated in this study. The RISI catalogue designations were RP-1 SC EBW shaped charge part number (PN) 167-8673, the RP-4 SC EBW shaped charge PN 188-7377, and the RP-4 SFF EBW self-forging fragment (SFF) PN 188-7378 (1). The jet properties from these A detonator, frequently a blasting cap, is a device used to trigger an explosive device.Detonators can be chemically, mechanically, or electrically initiated, the latter two being the most common. The commercial use of explosives uses electrical detonators or the capped fuse which is a length of safety fuse to which an ordinary detonator has
