Dry-Type Transformers

Power-Dry II™ Transformers
Square D Power-Dry II vacuum-pressure impregnated transformers are particularly suited for a wide range of commercial and industrial applications. This VPI process saturates the dielectric material, which contributes to its long life and durability. The secondary windings are constructed with sheet conductors and NOMEX® insulation.

Available in primary voltages from 2.4kV to 35kV in 112.5 through 13,000 kVA sizes with a 220C Insulation system. Secondary voltages are available through 15 kV.
