HD Hyundai Electric has started installing extra-high-voltage switchgear and transformers at SK hynix's new plants in Cheongju, TheElec reported on Oct. 26, citing industry sources.
TheElec said the job covers the P&T7 building and a mask fab that SK hynix is adding for high-bandwidth memory and other AI memory. The same report says HD Hyundai Electric has also booked high-voltage switchgear and cast-resin transformers for support buildings at the Y1 fab in the Yongin cluster. TheElec said the Cheongju P&T7 work is scheduled through July 2027, and the Yongin work through December 2027. It said the supplier had already provided switchgear, transformers and gas-insulated switchgear to SK hynix's M15 plant in Cheongju and M16 in Icheon.
The July 2027 and December 2027 dates are schedules TheElec reported, not announcements that the fabs are producing wafers.

A memory fab does not ship chips if this gear fails. Transformers step incoming high voltage down to the tools. Switchgear isolates a fault so it does not take the rest of the line with it. TheElec did not give a megawatt rating for the new packages, so this story does not say how much load they add.
Decisions SK hynix already made
TheElec said that in August SK hynix decided to invest 35.2 trillion won in a second Yongin fab, called Y2, and 19.1 trillion won in the Cheongju M17 plant, and that it plans four Yongin fabs by 2033. In June, the report added, SK hynix outlined a separate Honam cluster it valued at 400 trillion won. Those dates are earlier. The new fact on Oct. 26 is that installation of this supplier's gear at the Cheongju buildings has begun this month. Samsung has restarted Pyeongtaek Fab 5 in its own effort to catch SK hynix in high-bandwidth memory, as Voltgrid reported.
What was not disclosed
TheElec tied the installation start to industry sources, not to a filing or a release with a contract price. It named no dollar figure, no transformer count and no megawatts. HD Hyundai Electric is not on Voltgrid's company list. The tagged company is SK hynix, the customer whose fabs the equipment feeds. Nothing in the report says the Yongin or Cheongju lines have started wafer output.
