Custom Work
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. 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. Farady transformers are systematically designed to meet electrical stress and mechanical overloads. The windings are made of copper or aluminum. The use of diamond-dotted paper bonds the winding into a compact block while drying and increases short-circuit capacity.
3. THE TANK
The tank must be absolutely tight under mechanical stress. Special attention is paid to corrosion protection via sandblasting and multi-coating. In hermetically sealed transformers, corrugated walls absorb the change in fluid volume. The sheet-steel lids are bolted or welded to ensure they withstand the stress of transport and operation.
