IronCore T-Series Transformers

Premium dry-type and liquid-filled transformers delivering efficient voltage conversion with industry-leading low losses.

IronCore T-Series

Overview

The IronCore T-Series transformer line spans from 15 kVA dry-type distribution transformers through 20 MVA liquid-filled power transformers, serving every stage of the power delivery chain. Featuring advanced amorphous metal and grain-oriented silicon steel cores, the T-Series achieves DOE 2016 efficiency standards and beyond, reducing total cost of ownership and carbon footprint. Available with a wide range of taps, impedance options, and enclosure ratings.

Key Features

  • Amorphous metal core option reducing no-load losses by up to 70%
  • UL-listed 220 C insulation system for superior overload capability (dry-type)
  • Sealed-tank, nitrogen-blanketed design for maintenance-free operation (liquid-filled)
  • Copper or aluminum windings with full vacuum-pressure impregnation (VPI)
  • Factory-installed temperature monitoring with remote alarm contacts
  • K-factor rated models (K-4, K-13, K-20) for non-linear/harmonic-rich loads
