Class 105–220 applications require winding materials engineered to perform across a broad range of thermal ratings and electrical requirements. Magnet wire helps form the coils, motors, transformers, and components that must maintain insulation integrity and consistent performance under defined heat conditions.

Because each thermal class presents different design and durability needs, manufacturers need winding materials that align with application-specific temperature, processing, and reliability requirements. Essex Solutions provides magnet wire engineered to support performance from lower-temperature Class 105 applications through higher-temperature Class 220 designs.
