Grid Upgrade
Utility-grade power transformers for transmission, distribution, and substation expansion.
Backbone Power for the Grid
Hartwerk Power grid transformers support national and regional power networks with utility-grade oil-immersed units from 5 MVA to 100 MVA. Designed for continuous outdoor operation in any climate, they incorporate grain-oriented silicon steel cores for maximum efficiency.
With on-load tap changers (OLTC), conservator tank systems, and advanced DGA monitoring options, our grid transformers deliver the reliability that transmission and distribution networks demand.
