Transformer Inventory Long-Time Industry Leaders Our skilled team of electrical and mechanical engineers has decades of experience designing pad-mounted transformers for a wide range of applications, including: Oil and gas down-hole equipment (including submerged pumps with variable speed drives) Surface pumps Small utilities requiring distribution-style transformers Industrial clients We design and test each unit in-house to meet all industry standards, including IEEE, ANSI, NEMA, UL, and C-UL. Fast Response Time At SWE, we know how important it is for you to minimize any potential downtime, so we respond quickly to all your needs: Average RFQ response time: 48 hours Average lead time for standard transformers: 3-5 business days Finished goods inventory, standard stock, and JIT manufacturing will often minimize lead times. Average delivery time for custom transformers: Varies based on product complexity Specialty Transformer Types Some applications call for a standard transformer, while others require a custom solution. Our transformer team can work with you to identify the exact specifications you need, and we have the expertise and experience to customize your transformer when necessary. Available custom features include: 25 kVa single-phase to 7500 kVa three-phase transformers 480 volt to 69 kV class Designs for non-standard frequencies and high harmonic conditions Transient suppression Mineral oil or high-fire-point insulating fluid Designs for extreme conditions: Extreme ambient temperatures Hazardous locations High altitudes Paint systems for extreme environments Soft Starter Reactor Designed for starting large motors, this device detects and responds to voltage drops. The soft starter incorporates a vacuum contactor and timing circuits for auto bypass of the reactor after the motor achieves full speed, and features a tap switch to match the reactance to the application. Multi-Tap Transformers (FACT® Series) Our FACT® (full amp capacity transformers) series is a broad line of single-phase and three-phase distribution-style transformers. They are primarily designed for the rigorous duties of down-hole submersible pumps, surface pumps, and variable speed drive applications. Single-Phase Transformers: Single-phase step-down FACT® transformers are available with single primary voltages (FACT® 125) or dual primary voltages (FACT® 225). Three-Phase Transformers: Our FACT® III series are three-phase step-up designs with a 480 V primary voltage. Phase-Shifting Transformers Our phase-shifting transformers convert three-phase utility voltage to provide the 12, 18 or 24 (or higher) pulses required to feed modern multi-pulse variable frequency drives (VFDs). By using a multi-pulse VFD, you can reduce the need for expensive harmonic filters. Our phase-shifting transformers come in a variety of models to match the size of the VFD and the FACT® multi-tap transformer connected to its output. Poly-Auto Transformer: A 12-pulse phase-shifting transformer, this polygon auto transformer is designed to supply a 12-pulse motor drive, and reduces the need for expensive harmonic filters. 18- and 24-pulse models: We also offer 18-pulse and 24-pulse phase-shifting transformers (and higher) as custom designs.
