Specialty Transformers Ideal for oil & gas down-hole applications and other harsh industrial environments.

Designed and Manufactured in the USAThe Specialty Transformer Division of Southwest Electric Co. focuses on the design and manufacture of standard and custom small to mid-size liquid-filled transformers (including distribution and pad-mount transformers) from 25 kVA up to 7500 kVA. We deliver transformers individually or as part of a skid package, designed for quick set-up or relocation. The skid package can include a protective enclosure, a conditioned control room, switchgear, metering, reactors, lighting, and other desired features. We also provide integration into a complete power distribution system.

• Oil and gas down-hole and submerged pumps with variable speed drives

• Surface pumps• Small utilities requiring distribution

style transformers• Industrial clients

Application Environments• Average RFQ response time: 48 hours• Average lead time for standard product:

3-5 business days (finished goods inventory, standard stock and Just-In-Time manufacturing minimizes lead times)

• Average delivery time for custom product: Varies by product complexity

Responsive to Your RFQ

Our team of mechanical and electrical engineers is available to respond efficiently to your specific needs, with both standard and custom designs and configuration or manufacturing requirements, with strict testing and quality control measures. We will design and test to meet all common industry standards including IEEE, NEMA, and ANSI as requested.

Southwest Electric Co. has a dedicated manufacturing facility for custom transformers with nearly 100,000 square feet of space and an extensive array of testing and manufacturing equipment that includes:

• Dedicated coil sizing oven• 1.6MV, 80 kJ impulse generator• Haefely HIAS 743-2 digital impulse

analyzing system

• 350 kV dedicated hipot transformer• 180 Hz synchronous M-G set• Class 1, Div 2 hazardous locations

Specialty Transformer Overview

Multi-Tap Transformers—FACT® SeriesThe FACT® (Full Amp Capacity Transformers) series is a broad line of single-phase and three-phase distribution-style transformers primarily designed for the rigorous duties of down-hole submersible pumps, as well as surface pumps, and Variable Speed Drive applications. The FACT® series provides full amp capacity across a wide secondary tapping range with 25 or 50 externally selectable positions.Single Phase: Single phase step-down FACT® transformers are available with single primary voltages (FACT® 125) or dual primary voltages (FACT® 225).Three-Phase: Our FACT® III series are three-phase step-up designs with a 480 V primary.

Phase Shifting Transformers—Improves the Ripple FactorOur phase shifting transformers convert the three-phase utility voltage to provide the 12, 18, 24, or higher pulses required to feed modern multi-pulse Variable Frequency Drives (VFD). Our phase shifting transformers are sized to match the VFD and the FACT® multi-tap transformer connected to its output and come in a variety of models.Poly-Auto Transformer: A 12-Pulse phase-shifting transformer, this polygon auto transformer is designed to supply a twelve-pulse motor drive.18 and 24-pulse models (and higher): Also available as custom designs.

Soft Starter Reactor Designed for the starting of large motors, this device is designed to detect and respond 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 voltage drop for the application.

Custom Designs • 25 kVA single phase through 7500 kVA

three phase• 480 volt through 69 kV class• Designs for non-standard frequencies• Designs for high harmonic conditions• Designs to meet special footprint needs• Transient suppression• Mineral oil or high fire-point insulating fluid• Very low loss designs with amorphous cores

Extreme Conditions • Extreme ambient temperatures• Hazardous locations• High altitudes• Paint systems for severe environments

Other features to your specifications as well as the leading industry standards: IEEE, ANSI, NEMA, UL, C-UL

Our Standard and custom transformers include:• 25 kVA single phase through 7500 kVA three-phase (including full-amp capacity and polygon)• Designs for 50 or 60 Hz, high harmonic conditions, extreme ambient temperatures and

harsh environments.• 600 V through 69,000 V class
