Starting with aerospace wire that has certified insulation properties, where every foot of it is tested, and so on. Tensolite-Carlisle was usually the supplier. If it absolutely has to be COTS maybe talk to these guys: http://www.appliedps.com/ap-1289-high-voltage-isolated-scr-gate-driver -- Regards, Joerg http://www.analogconsultants.com/
