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