Engineering - SPX Waukesha Quality Begins Here

For over 40 years, SPX Transformer Solutions has engineered power delivery solutions that provide consistent performance and long service life. Waukesha® transformers, whether engineered in Goldsboro, NC or Waukesha, WI, are synonymous with quality and reliability and are custom designed to meet specific customer requirements or applications needs.

Transformers Quality Inside

Waukesha® power 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 SPX Waukesha engineers in Wisconsin and North Carolina the opportunity 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, helping to optimize the mechanical design. Computer data also furnishes precise information on flux density, conductor size, cooling requirements, dielectric characteristics, power losses and more.

Combined with SPX Waukesha’s more than 40 years of transformer manufacturing and engineering history, these design tools help ensure every Waukesha® transformer provides consistent, dependable performance and long service life. The following drawing of a representative Waukesha® power transformer illustrates many of our quality design features built into every unit:

2. Lamination width customized to achieve a near perfect circle core cross section, resulting in the most 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 inspections.

6. Exterior tank coated
to a minimum thickness of 3 mils; this coating has superior endurance characteristics and meets ANSI C57.12.28 standards.

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 De-Energized Tap Changer (DETC)
features simple and compact in-line contact arrangement (Patent Number 5,744,764).

10. Load Tap Changer
per IEEE C57.131 and IEC 60214; Waukesha's UZD® is designed to withstand up to a half-million operations without need for contact replacement.

11. NEMA 3R Control Box
is an enclosure for customer interface with transformer monitoring equipment, LTC and transformer cooling controls. Anti-condensation heaters, covered document box, three-point door latch and padlockable door handle are standard as is stainless steel external hardware and a large, removable bottom plate for customer conduits and cabling.
