Transformers are capital goods with a life expectancy that exceeds decades. During these decades, the transformers must remain economical. Buyers should, therefore, not only weigh the initial costs - but also consider maintenance and operational costs, including costs for no load and load losses.
In this critical decision, quality equals economy, even if the initial costs are sometimes higher.
SGB transformers are the rational choice as they are economical, have high efficiency, use high quality material and reliable manufacturing processes during production. The evidence of quality is certified by routine-, type- and special-tests.
An optimum core design is achieved by the use of high quality cold rolled, grain oriented electrical sheet steel, step-lap cutting procedure and modern lamination methods without using internal bolts.
Reliable windings such as LV foil windings and HV layer windings guarantee short circuit rigidity and impulse voltage proof layout of the transformers.
Hermetically Sealed Transformers having tanks with corrugated side walls assure the customers low maintenance costs. Vacuum drying of the active parts including oil filling in a vacuum chamber guarantee the constant high quality of the transformer's oil and the transformer itself.
