Customers We Serve 

Altran partners with medical device manufacturers and equipment developers across the healthcare industry. Our client base includes:

• Medical Imaging equipment manufacturers: (High Voltage Step-up Transformer, Filament Transformer, Bias Transformer)
• Medical equipment: (Isolation Transformer, Filament Transformer, Signal Transformer, Power Transformer)

Custom-Only Solutions 

Every transformer we manufacture is built as a custom solution. We maintain no inventory of standard catalog products or MIL-SPEC units. Our design process involves direct partnership with clients throughout development to ensure final products meet your performance criteria, size constraints, and regulatory compliance requirements.

Made In U.S.A. Custom Medical Transformers

Every custom medical transformer is wound, potted, and tested at our Crystal Lake, Illinois, manufacturing facility. Our domestic production approach consolidates engineering, procurement, and quality control teams in one location to streamline communication and safeguard proprietary designs. This integrated process delivers consistent builds that satisfy your specifications while meeting stringent medical device safety standards.

Our experienced technicians manage each unit through every production stage, from initial winding to final encapsulation, using precision instruments to verify electrical characteristics throughout assembly. Completed transformers undergo rigorous environmental testing that simulates the demanding conditions of hospital equipment rooms and clinical environments. Units are cleared for shipment only after passing our comprehensive quality protocols to guarantee reliable operation in life-critical medical systems.

Core Material Selection & Medical-Grade Reliability

Silicon steel laminations are used in most medical power transformers due to their high saturation flux density and cost-effective manufacturing. These thin steel sheets contain silicon alloy that maintains magnetic linearity under the variable loads common in medical equipment. The material handles frequent on-off cycles without degrading magnetic properties over the transformer’s operational lifespan.

Ferrite cores offer advantages in high-frequency medical applications where size and weight matter. These compressed iron oxide materials can be gapped to prevent saturation and provide stable inductance values across temperature ranges found in hospital environments. Nickel-iron alloys deliver superior magnetic permeability for sensitive signal applications where even minor distortion affects diagnostic accuracy. Each core material selection balances magnetic performance against the physical constraints and electrical demands of the specific medical device.

Winding Techniques for Medical Applications

Medical transformers employ layered isolation barriers between primary and secondary windings to meet patient safety standards. These multiple insulation layers have specific dielectric strengths that prevent voltage breakdown even under fault conditions. Split bobbin construction physically separates primary and secondary windings to increase creepage distances and reduce the risk of electrical contact between circuits.

Triple-insulated wire provides an additional safety layer in patient-connected devices. This wire construction includes three distinct insulation layers that each meet full voltage isolation requirements independently. Interleaved winding patterns distribute voltage stress evenly across insulation systems to prevent localized breakdown. Each winding technique undergoes testing to verify leakage current remains below the microampere levels mandated for medical device safety standards.
