Technical Specifications

Tailor-Made Transformer Solutions

Henka’s Dry Type Distribution Transformers come in single-phase (3 to 350kVA) and three-phase (5 to 900kVA) with a 1.2kV voltage class. They use self-cooled copper or aluminum windings with a 220°C insulation system and a standard 150°C temperature rise, with lower temperature options available. Built for efficiency, they meet DOE 2016 and NRCan 2019 energy standards and comply with NEMA ST-20 sound levels. Standard enclosures include Type 1 or 3R indoor with an ANSI 61 grey finish, with options for thermal sensing, electrostatic shielding, surge protection, and K-factor ratings for harmonic loads.

CSA-certified up to 900kVA and UL-listed up to 750kVA, Henka transformers are reliable, durable, and easy to install.
