Pole Mount
RMPAC liquid-filled polemount transformers are designed, built, and tested in accordance with all applicable IEEE standards. Each unit is built to comply with the latest DOE efficiency regulations. They are ideal for utility applications requiring single-phase and three-phase distribution.
Product Scope
- 5 kVA–333 kVA
- High voltages: 2,400 to 34,500 (up to 150 kV BIL)
- Low voltages: 120/240, 240/480, 277
1-Phase Padmount
RMPAC tamper-proof, liquid-filled, single-phase pad-mounted (or padmount for short) transformers are designed, built, and tested in accordance with the highest industry standards. They feature a clamshell cabinet design allowing easy access in a compact footprint.
Product Scope
- 5 kVA - 250 kVA
- Up to 19.9 kV (150 kV BIL)
3-Phase Padmount
RMPAC tamper-proof, compartmentalized, liquid-filled, pad-mounted (or padmount for short) transformers are all-in-one units designed, built, and tested in accordance with the highest industry standards and can be customized with over-current protection, and sectionalized switching to give you maximum control over your distribution system.
Product Scope
- 30 kVA - 10,000 kVA
- Up to 35,000v
Substation Transformers
RMPAC’s liquid-filled distribution substation, and power-class substation transformers are designed, built, and tested in accordance with the highest industry standards including NEMA, ANSI C.57, DOE, and IEEE as applicable. With a range of customizable features, RMPAC substations can be configured to maximize performance, minimize potential arc flash exposure, and address environmental concerns. All designs can be supplied with full, or partial length air terminal chambers to make installation easy.
Product Scope
- 300 kVA - 100,000 kVA base
- Up to 145 KV
Dry-Type Transformer
RMPAC 600v transformers are designed, built, and tested in accordance with the highest industry standards including NEMA, ANSI C.57, DOE, and IEEE as applicable. Whether your low voltage power need is indoors or outdoors, RMPAC specializes in 600v transformers that can be customized for both step-up and step-down power distribution, energy storage, and machine-tool applications.
Product Scope
- kVA range: 5 kVA -1,000 kVA
- Voltage range: Up to 800v
Cast Coil Transformer
RMPAC’s cast coil transformers are designed, built, and tested in accordance with the highest industry standards including NEMA, ANSI C.57, DOE, and IEEE as applicable.
They are engineered for both indoor and outdoor applications and need minimal maintenance due to their rugged construction. Cast coil transformers use environmentally safe insulation systems that don’t require the fire proof vaults and catch basins that liquid filled transformers need. This allows the installation of cast coil transformers inside buildings close to the load, improving overall system regulation and reducing costly secondary line losses. The fiberglass reinforced construction of these units also provides higher short circuit strength and impulse voltage strength.
Product Scope
- 100 kVA - 10,000 kVA
- Up to 46kV (250kV BIL)
