Many sectors rely on transformer OEMs and service firms, including electric utilities, IPPs, oil and gas, mining, steel and metals, cement, rail, ports, data centers, telecom hubs, hospitals, and large commercial real estate. These industries depend on suppliers for new units, retrofits, diagnostics (DGA, PD, tan-delta), refurbishment, emergency repairs, and asset-management advice to minimize downtime and extend the life of critical MV/HV infrastructure.
