SUPACT Insulation System

Testing

A unique mica/glass insulation system, vacuum pressure impregnated with 100% solids epoxy Resin, and high-build epoxy varnish

for finish treatment ensures the strongest resistance to chemical attack or contamination.

Hyosung SUPACT Insulation system has demonstrated its durability under the most arduous industrial and climatic conditions in

high voltage drives.

Routine Test Scope

Our factories use state of art test facilities and equipments to verify design data in accordance with design standards, including noise

testing to IEC 34-9, NEMA MG-3, and IEEE standard 85. Routine test reports are furnished without charge, and include the
