Technical Specifications

Tailor-Made Transformer Solutions

Henka’s VPI/VPE Power Transformers range from 100–5,000 kVA (single-phase) and 300–15,000 kVA (three-phase) with voltage ratings up to 46kV (250kV BIL). They feature air-cooled copper or aluminum windings, a 220°C insulation system, and VPI epoxy impregnation for durability, with VPE options for added protection. Built to North American energy standards, they include +/-2 x 2.5% primary taps and meet IEEE C57.12.01 sound levels.

Standard enclosures are Type 1 indoor, with Type 2, 3R, 4, 4X, and 12 options, all finished in ANSI 61 grey powder coat. CSA-certified, UL-listed, and ISO 9001:2015 compliant, Henka transformers undergo extensive testing and offer optional features like seismic mounting, surge protection, anti-condensation heaters, and ground fault relays for reliable performance in demanding environments.
