Custom Work- In Macrocosm And In Microcosm
1. THE IRON CORE
Whether in design, manufacturing methods or materials the cores of Farady transformers represent the latest state of technology. The silicon alloyed electric sheet steel used is grain-oriented, cold-rolled and insulated on both sides, guaranteeing low losses and noise and these values are even improved by laser treatment. Standard use of step-lap cutting additionally minimizes losses and noise.
2. THE WINDING
The winding as the centerpiece of the transformer must be especially protected against high electrical stress and mechanical overloads. Farady transformers are systematically designed to meet these requirements. The use of "diamond-dotted paper" bonds the winding into a compact block while drying and increases the short-circuit capacity additionally.
3. THE TANK
The tank must be absolutely tight under mechanical stress. Pretreatment of the surface by sandblasting contributes to corrosion protection, just like multi coating with preset drying times. In hermetically sealed transformers, the corrugated walls absorb the change in volume. The sheet-steel lids are bolted together with the tank or welded on request.
