On April 16, HD Hyundai Electric announced that it had recently completed the final approval test of a 400-kilovolt (kV), 460 MVA-class transformer utilizing eco-friendly insulating oil. This transformer is the largest of its kind in Korea in terms of capacity and will be supplied to a substation operated by the UK power company National Grid in the United Kingdom.

The eco-friendly insulating oil transformer uses synthetic ester oil, which is highly biodegradable, instead of conventional mineral oil. Compared to mineral oil, synthetic ester oil has a higher ignition point, reducing the risk of fire, and has a lower environmental impact in the event of oil leakage. As such, it is suitable for sites that require both fire safety and environmental protection.

Transformers using eco-friendly insulating oil are more technically demanding to manufacture than conventional models. In particular, the higher the voltage and capacity, the more complex the challenges related to heat management and insulation become, increasing the overall technical complexity. Only a handful of companies worldwide are capable of stably producing such products.

Recently, global demand for eco-friendly transformers in the power infrastructure market has been rising rapidly. According to market research firm Grand View Research, the global eco-friendly transformer market is expected to grow from approximately $1.22 billion in 2024 to around $1.81 billion by 2030. The compound annual growth rate during this period is projected to reach 6.9%.

A representative from HD Hyundai Electric stated, "High-voltage, large-capacity eco-friendly insulating oil transformers are highly advanced products that require both superior insulation and cooling performance as well as reliability," adding, "We will continue to actively expand our presence in the eco-friendly power equipment market through ongoing research and development."
