Hello all,

My shipment of 145 Cornell Dubilier Caps arrived from Richardson 
Electronics today. These are 2000VDC, 0.15uF caps, identical to the 
Geek Group caps. I intend to use twelve strings, with twelve caps per 
string, for 0.15uF at 24kVDC. This will be used with my 11.5kV 10kW 
pole pig system, with a 400/200/100 BPS sync gap (variable). This MMC 
will be huge, with 144 caps in total - second only to Robin Copini's 
(as far as I know). Due to the sheer number of caps, I want to 
package them as efficiently as possible to conserve space. I was 
wondering if anyone has had any problems with mounting them side by 
side (as opposed to end to end). I am considering mounting them side 
by side with a 5mm gap between. This will let me fit 4 strings of 12 
on a single poly cutting board. Three boards will be placed in 
parallel for 0.15uF. Can anyone see any problem with this 
configuration? I figure with 2kV across each cap, and a 5mm gap 
between each, I should have no problems with arc overs. What do you 
think? In addition, is this beast over engineered enough to be 
reliable, or should I go for 13 caps per string?


Cheers,

Greg Peters.
