Facilities :

Production Process - Winding :

Production Process - Vapour Phase Drying :

Fully automatic vapor phase drying plant. Drying cycle time depends on the size of the transformer. All transformers regardless of size apply this process. Complete interior assembly applies hot vapor drying procedure to remove moisture prior to vacuum filling with oil.

Production Process - ( Core and Win ding ) :

WINDINGS UNDER SHRINKAGE

CRGO

CRGO

• Step lapped fully mitered cores are used
• The required width of low loss core steel are purchased from Nippon Steel, Japan, WISCO, China.
• Laminations are cut to length on GEORG cut- to-length line with step-lap cut and automatic stacking functions to high dimensional accuracy.
• Special clamping equipment ensures the tightness of steel core.
• Assembled in dust-free workshop
