Technical Specifications
Tailor-Made Transformer Solutions
Henka’s Autotransformers come in single-phase (3–333kVA) and three-phase (5–1,000kVA) with a 1.2kV voltage class. They feature air-cooled copper or aluminum windings, a 220°C insulation system, and a standard 150°C temperature rise (optional 115°C or 80°C). Designed to meet NEMA ST-20 sound levels, they are housed in a Type 1 or 3R ASA 61 grey steel enclosure.
CSA-certified, UL-listed, and built to ISO 9001:2015 standards, they offer optional features like primary voltage taps, thermal sensing, electrostatic shielding, surge protection, and K-factor ratings for harmonic loads.
