20kV Dry-Type Power Transformer, Class H Insulation
Applications
The 20kV dry-type power transformer is made of premium-grade insulating components, ideal for any power distribution sites as well as compact substations and mobile substations.
Standards
IEC60076
GB10094
Features
Multi-step lap core consisting of laminated iron plated stacked together and held tightly by yokes. High voltage coils come fitted with winding combs for rigid support and optimal insulation. High and low voltage windings are interconnected. The entire core-winding assembly receives vacuum pressure impregnation. The main insulation material is NOMEX insulation paper. Low core loss, minimized noise and reduced chance of partial discharge. Mechanically strong and made via innovative processes, this power transformer has high overload capacity.
