Dong Anh Electrical Equipment Corporation - Joint Stock Co is a Vietnam-based electrical equipment manufacturer primarily engaged in the design, engineering, manufacturing, installation, and servicing of power transmission and distribution equipment. Founded in 1971 and headquartered in Hanoi, Vietnam, the corporation operates through several business segments, including Power Transformers, Distribution Transformers, Electrical Switchgear and Components, Steel Structures, and Technical Engineering Services. Its product portfolio includes single-phase and three-phase power transformers rated up to 500kV; oil-immersed, dry-type, and amorphous alloy energy-efficient distribution transformers; current and potential instrument transformers; medium- and low-voltage switchboards, disconnectors, control panels, and prefabricated package substations; bare copper and aluminum conductors; and galvanized steel towers and support structures for transmission lines and substations. In addition, the corporation provides high-voltage testing, commissioning, diagnostic monitoring, maintenance, overhaul, and engineering, procurement, and construction (EPC) contracting services for power grid systems. Dong Anh Electrical Equipment Corporation primarily serves national power utilities, industrial manufacturing complexes, infrastructure developers, and renewable energy operators across Vietnam and regional Southeast Asian markets. In recent corporate and operational developments, following the restructuring of its shareholder base and ownership transition from Vietnam Electricity (EVN) toward strategic industrial investors, the company has expanded its manufacturing capacity for ultra-high-voltage 220kV and 500kV power transformers to align with Vietnam's National Power Development Plan VIII (PDP8). The corporation has also launched smart grid-compatible digital substations and specialized step-up transformers engineered for utility-scale solar and wind power projects, while modernizing its high-voltage testing laboratories and expanding maintenance service partnerships for regional electrical infrastructure.
