Comprehensive Product Overview

Deep dive into the engineering, applications, and specifications of our Three Phase 25kVA 30kVA 50kVA 220V to 380V Isolation Transformer.

Reliable Voltage Step-Up Solutions

Engineered for demanding industrial environments, this series of three-phase isolation transformers provides seamless voltage elevation from 220V to 380V. This is essential for facilities running imported 380V machinery on standard 220V grids, or when power distribution requirements dictate higher voltage levels.

Available in 25kVA, 30kVA, and 50kVA capacities, this dry-type step-up transformer excels at mitigating disruptive grid noise, dampening voltage spikes, and eliminating ground loops thanks to its true galvanic isolation. Utilizing a high-efficiency magnetic core and premium windings, it ensures reliable, continuous 24/7 operation.

  • True galvanic isolation protects sensitive electronics from common-mode noise.
  • Efficiently steps up 220V three-phase input to 380V three-phase output.
  • Available in capacities of 25kVA, 30kVA, and 50kVA.
220V to 380V Isolation Transformer Overview

Engineering Excellence at Every Level

Our step-up isolation transformers are built utilizing state-of-the-art manufacturing processes to ensure maximum efficiency, durability, and operator safety.

Galvanic Isolation

True Galvanic Isolation

Electrically separates the primary and secondary windings, effectively blocking DC signals, high-frequency noise, and protecting equipment from ground faults.

High Efficiency Core

High-Efficiency Core

Constructed with premium cold-rolled grain-oriented silicon steel sheets, stacked with precision to minimize core losses and operational noise.

VPI Windings

Precision VPI Windings

Vacuum Pressure Impregnated (VPI) windings provide superior dielectric strength, excellent heat dissipation, and high resistance to environmental moisture and dust.

Versatile Industrial Integration

The 220V to 380V isolation transformer is essential for bridging the gap between local power grids and specialized equipment requiring higher operating voltages, ensuring clean, stable, and safe power.
