Medium Voltage Dry-Type Transformers
Fire-Safe Indoor Power — No Oil Required
Medium voltage dry-type transformers use solid insulation instead of liquid, making them the preferred choice for indoor installations where fire safety, environmental concerns, and space constraints are critical factors. Commonly found in commercial buildings, hospitals, data centers, manufacturing plants, and high-rise structures, dry-type transformers deliver reliable voltage transformation without the risks associated with oil-filled equipment.
Xplor Energy supplies medium voltage dry-type transformers in cast resin and VPI (Vacuum Pressure Impregnated) configurations. Cast resin units encapsulate windings in epoxy for maximum moisture and contamination resistance, while VPI units offer excellent performance in standard indoor environments.
Our repair services include complete coil rewinding, insulation system restoration, enclosure refurbishment, and full electrical testing — returning units to their original rated performance at a fraction of new equipment cost and lead time.
