​​​RP-880​

P/N 188-7354​

The RP-880 Fluid Desensitized, RDX, EBW Detonator is purposely designed to misfire when immersed in a fluid and fire properly when fired in air. Misfiring or firing refers to the output portion of the detonator. The RDX provides a higher operating temperature capability as compared with the RP-88 Fluid Desensi-tized, PETN, EBW Detonator.​



PARTS DESCRIPTION
1. Output pellet:454 mg of RDX with binder
2. Cup:Aluminum, anodized gold, 0.007 inch thick
3. Sleeve:Brass
4. Disc
5. Pellet:123 mg of RDX with binder
6. Initial pressing:82 mg of RDX
7. Bridged head
PERFORMANCE
* Threshold burst current .......... 450 amps
* Threshold voltage .................. 800 volts (approx.)
* Transit time ............................ 10.5 µ sec. (approx.)
Note: Performance values are based on a firing circuit with the following parameters:
C = 1.0 µ farad, L = 0.65 µ henry, R = 0.16 ohm

Caution: While EBW and EFI Initiators are inherently less susceptible to accidental detonation during handling and set-up than devices containing primary explosives, electrical and electronic firing systems are sensitive to transient electrical energies which could cause premature triggering or firing. The blasting area must be clear of personnel and equipment before the detonator leads are connected to any RISI Firing System. Only approved RISI Firing Systems should ever be used to initiate or detonate any explosive product manufactured and authorized for sale by RISI.
