Waukesha® Transformers have earned a reputation for quality and are custom designed to meet specific customer requirements. This process begins by accessing design data from one of the industry’s largest computer-based libraries. Hundreds of alternative core and coil configurations are reviewed for each proposal, allowing Waukesha Electric Systems' engineers to select the optimum electrical design that will satisfy a customer's individual needs. Other programs then plot the forces that a coil will experience during a short circuit, which helps to optimize the mechanical design. Computer data also gives precise information on flux density, conductor size, cooling requirements, dielectric characteristics, power losses and more.

Combined with Waukesha’s nearly 40 years of transformer manufacturing and engineering history, these design tools help ensure that your Waukesha® transformer provides consistent, dependable performance and long service life.

QUALITY DESIGN FEATURES
The following drawing of a representative Waukesha® medium-power transformer illustrates many of our quality design features:

1. Core (no-load) losses minimized by utilizing laser-scribed, super-grain-oriented steel.
2. Lamination width customized to achieve a near perfect-circle core cross section, resulting in the efficient use of materials plus a lighter, more compact, high performance transformer.
3. Coil assembly rigidly braced in a high-strength frame that distributes clamping forces around the full circumference of the windings.
4. Submerged-arc welding process produces deep penetration welds, virtually eliminating leakage from welded tank joints.
5. Inside tank surfaces are painted white to facilitate internal inspection.
6. Transformer exterior coated to a minimum thickness of 3 mils; this coating has superior endurance characteristics and meets the ANSI C57.12.28 standard.
7. Galvanized radiators provide excellent corrosion resistance and require minimal maintenance (fan guards and blades also galvanized).
8. Material-stabilized coils are pressure-fit within the core frame.
9. Patented DETC (De-Energized Tap Changer) features simple and compact in-line contact arrangement (Patent Number: 5,744,764)
10. Waukesha® Type UZD Load Tap Changer designed to withstand up to a half-million operations without the need for contact replacement.
11. Control Box/Enclosure features IEC standard components and is easy to maintain and service in the field.

Whatever the market or customer need, when it comes to transformers, components or service support, Waukesha quality will be there for you!
