H Line - HGF - High Voltage - TEFC

( Up to 2,800 KW )

Description :

WEG high voltage motors, H line present simple and compact construction and are manufactured in finned cast iron frames being very robust for severe duty applications.

Besides counting on a structural block that forms the frame, external cooling fins along with cooling ducts and an internal and another external fans are also provided resulting in an inside temperature balance with further extension of its winding life time and improved performance.
