Active parts for rotating electric machines
IHB Electric JSC offers the two most famous and wide-used insulation systems.
Global VPI insulation system provides reliable isolation of electric machines with rated power up to 11 kV and guaranteed operational life. This insulation system is generally used at full repair of the stator winding and manufacturing of new stator core, providing higher energy efficiency compared to older insulation systems.
The patented by IHB Electric JSC application of insulation system "Hydro Vacuum Pressing" allows laying of reliable isolation for high voltage, which during factory testing survived test voltage of 40 kV.
The second insulation system, which is used at partial repair of active parts and voltage higher than 11 kV, is the system Resin Rich.
