Technical Specifications
Tailor-Made Transformer Solutions
Henka’s Dry Type Distribution Transformers (5–900kVA, 1.2kV) deliver efficient, air-cooled power with copper or aluminum windings and a 220°C insulation system. They meet North American energy standards, support non-sinusoidal loads with a K-factor of 4 (higher options available), and include +/-2 x 2.5% primary taps for voltage adjustments. Built to NEMA ST-20 sound levels, they come in ANSI 61 grey Type 1 or 3R enclosures, with CSA and UL certifications.
Optional features include thermal sensing, electrostatic shielding, surge protection, and anti-vibration pads for added durability and performance.
