2. Main characteristic:
The product's design & manufacture are adopted sealed & non-lift-core technique.
Comparing to National Standard GB/T6451-1999, the product's on-load loss is decreased 23% averagely & no-load loss is decreased 13.3%.
Adopting vacuum oilling technology, the insulation intensity is increased.
The silicon sheet is cut on GEORG production line introduced from Germany.
It successfully passed National transformer quality centre's short circuit test. |
