Hi Tomas,

Yes you can connect the two 5KW transformers together providing:

1.  The secondary of each in not center tapped grounded.
2.  If each transformer only has one bushing, you dont need to worry 
about forming a center tap between the two transformers.  If two 
bushings are available, you will need to ground one of them.
3.  You phase the primaries correctly so one transformer puts out a 
negative voltage when the other transformer puts out a positive voltage.

I recommend that you DON'T USE these high power transformers until 
you gain more experience.  These power levels can be deadly.  Use the 
4.5KV NST for your first coil.
