Description
High Power Three Phase EI240 Transformer 50kVA 80kVA 100kVA
The Three-Phase EI240 Transformer is an ultra-heavy-duty magnetic component designed for large-scale industrial power distribution and voltage regulation. As one of the largest standard sizes in the EI laminated series, the EI240 is engineered to support massive power requirements, typically ranging from 20kVA to over 100kVA. Operating at 50Hz or 60Hz, this transformer serves as a robust backbone for entire production lines, providing high-reliability voltage step-down, step-up, or total galvanic isolation for critical infrastructure.

Product Features
  • High-Capacity EI240 Silicon Steel Core: Utilizes premium, high-permeability laminated silicon steel sheets to maximize magnetic flux efficiency while minimizing eddy current and hysteresis losses.
  • 100% Electrolytic Copper Windings: Features high-grade pure copper coils, providing superior electrical conductivity and exceptional durability under continuous heavy-load cycles.
  • Precision Phase Balancing: Optimized three-phase winding architecture ensures perfect voltage symmetry and minimal phase displacement for sensitive electronics protection.
  • Dry-Type Vacuum Pressure Impregnation (VPI): Deep VPI process with high-grade insulating resin solidifies the structure to prevent moisture ingress and mechanical noise.
  • Robust Terminal Blocks: Equipped with heavy-duty, high-current busbars or terminal blocks for secure and low-resistance electrical connections.
