Overview
- HD Hyundai Electric, which completed final approval testing Thursday, will ship a 400 kV, 460 MVA transformer to Britain’s National Grid.
- The unit uses synthetic ester insulating oil that is biodegradable and has a higher ignition point than mineral oil, cutting fire and spill risks at urban and renewable sites.
- Designers reworked insulation and cooling to suit the alternative oil, since high voltage and capacity raise heat and electrical stress inside the transformer.
- A company official called these large eco models technology‑intensive and said HD Hyundai Electric will keep investing in R&D, citing strong overseas demand and a full U.S. order book even as tariffs complicate exports.
- Grand View Research projects the eco‑friendly transformer market to grow from $1.22 billion in 2024 to $1.81 billion by 2030, reflecting steady global uptake.
