PUCARO duct spacing presspaper is used for the main and cooling ducts in oil-filled power, distribution and traction transformers.

PUCARO duct spacing presspaper is produced using special processing procedures, which guarantee high compaction and dimensional stability. The exceptional mechanical properties of the insulation material provide the required safety in the event of a short circuit. Its ability to be impregnated with oil strengthens the electromechanical properties so that, in this combination, the components have excellent insulation properties.
