The power grid and cables theme covers Korean companies that make transmission and distribution equipment, including high-voltage cables, transformers, switchgear, and related grid infrastructure. Korean investors often group these firms together because grid expansion and upgrades are needed to connect new power sources, such as renewables, and to meet rising electricity demand from data centers and electrification. Companies in this group are typically discussed in terms of their exposure to domestic utility projects and overseas grid orders.
