/The Magnetics Design Advantage/
Engineered for maximum environmental safety and durability.
Traditional liquid-filled transformers pose severe environmental contamination and safety risks indoors. Our solid dielectric dry-type configurations utilize advanced insulation matrices and optimized airflow pathways to handle heavy electrical loading without toxic cooling fluids.
01
Fire-Safe Engineering
Constructed entirely with self-extinguishing, flame-resistant solid materials, perfectly eliminating the need for expensive indoor fire deluge systems.
02
Zero Leak Hazard
Completely oil-free design, wiping out the need for fluid containment basins, drainage systems, or long-term environmental soil monitoring.
03
High Dielectric Build
Wound with premium Nomex® paper or advanced Class H epoxy structures to protect the internal core from high thermal and cyclic strain.
04
Minimal Maintenance
No fluid samples to draw, no dissolved gas analysis (DGA) tests required—just standard, periodic dust removal for decades of operation.

What Our Clients Say
by Magnetics Design substations.
Advanced transformer solutions designed to improve power quality, reduce harmonics, and maximize system performance.
We were struggling with severe harmonic distortion on our main drive lineup. Magnetics Design engineered a 24-pulse phase shifting unit that dropped our THD well below IEEE 519 limits.
Brian John
My Client
Magnetics Design turned around a quote for a custom 18-pulse transformer the same day. The build quality was exceptional, and it arrived right on schedule for our shutdown window.
Felix Chou
My Client
The VFD isolation properties on these units are bulletproof. We source all our specialty phase shift transformers from the Magnetics Design team because they get the specs right the first time.

Questions engineers ask
What are the key benefits of dry-type transformers over liquid-filled units?
Dry-type transformers rely on ambient air circulation and solid insulation rather than mineral oil or liquid dielectrics. This completely eradicates fire hazards, toxic spills, and the need for fluid containment vaults. They are heavily favored for indoor commercial buildings, hospitals, schools, and heavy industrial facilities where environmental safety is paramount.
What is the difference between VPI and VPE dry-type transformers?
Vacuum Pressure Impregnation (VPI) utilizes premium high-temperature polyester or epoxy resins deeply penetrated into the core and windings under vacuum pressure. Vacuum Pressure Encapsulation (VPE) adds an advanced layer of silicone resin protection, offering far superior moisture resistance, anti-corrosion behavior, and protection against airborne contaminants in severe or outdoor environments.
What are your typical lead times and logistics arrangements?
Lead times depend heavily on whether your design parameters match standard pre-engineered stock frame sizes or require bespoke mechanical sizing from our engineering team. We prioritize extreme response times, providing comprehensive engineering proposals on the same day. All units ship securely balanced and freight-coordinated directly from our manufacturing facility to your job site.
Are Magnetics Design dry-type transformers manufactured domestically?
Yes. Magnetics Design is an Illinois-based manufacturer. Every single transformer is completely engineered, assembled, and factory-tested right here in the USA. This allows our equipment to meet the strict compliance baselines needed for the Buy American Act (BAA) and municipal infrastructure bids.
What type of warranty protection is included?
Every dry-type transformer we ship comes with our standard 3-year warranty covering any flaws in workmanship or material integrity. We evaluate every configuration through exhausting full-scale insulation and electrical testing protocols before it rolls out of the factory to guarantee absolute reliability at commissioning.
