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. Numerically controlled cutting machines provide for careful treatment in the cutting process in order to avoid mechanical tension in the core and thus unwanted properties right from the beginning. Standard use of step-lap cutting additionally minimizes losses and noise.
  1. THE WINDING
    The winding as the centerpiece of the transformer must be especially protected -both against high electrical stress due to external over voltages and against mechanical overloads by short circuits.Farady transformers are systematically designed to meet these requirements. The windings are made of copper or aluminum.Low-voltage windings are made of strip or flat wire, and the high voltage windings are manufactured from round or profile wire. The use of insulating paper that is partially coated with epoxy resin ("diamond-dotted paper") bonds the winding into a compact block while drying and increases the short-circuit capacity additionally.
  1. THE TANK
    Whether during transport or operation -the tank must be absolutely tight under mechanical stress. Preconditions to achieve this are constructional experience, the most modern calculation methods and high-quality welding work. Special attention is paid to corrosion protection. Pretreatment of the surface bysandblasting contributes to corrosion protection, just like multi coating with preset drying times for each layer. On request, hot-dip galvanization provides for even better protection. The tank must dissipate the entire heat loss of the transformer into the ambient air. This makes the volume of the transformer fluid change. In hermetically sealed transformers, the corrugated walls absorb the change in volume. In the case of expansion tank transformers, the conservator compensates this change. The sheet-steel lids of Farady transformers are bolted together with the tank or welded on request. In any case the steel thickness and the bracing is dimensioned in such a way that the lid withstands the stress of transport and operation.
