I understand that there are standard requirements for separation of separate but parallel 13.8KV power and FOC duct banks from 300mm onwards depending on parallel running distance but i was wondering whats the minimum which can be kept. There is a corridor where i have to run 13.8KV power cables in one CUBIS PVC Multi Duct Bank and in parallel FOC CUBIS PVC Multi Duct Bank. Will it make a difference if I have all cables in both duct banks as armored to reduce the EMI interference? Any chance the separation can be brought down to 200mm or less with some insulation in between these ductbanks?
