Industry Overview

Oil-immersed transformers primarily serve power transmission and distribution, industrial power consumption, infrastructure, and large commercial facilities, serving as crucial equipment for ensuring power supply reliability and grid stability.

Due to their high capacity, high reliability, excellent heat dissipation, and strong adaptability to harsh environments, oil-immersed transformers are widely used in medium- and high-voltage distribution networks.

With the accelerated industrialization and urbanization in Vietnam, electricity demand continues to grow, significantly increasing the demand for oil-immersed transformers from substations, industrial parks, infrastructure projects, and commercial complexes. The demand for high-capacity, high-reliability oil-immersed transformers is particularly concentrated in industrial and population-intensive areas such as Hanoi, Haiphong, and Bac Ninh in the north, and Ho Chi Minh City, Binh Duong, and Dong Nai in the south.

Large, high-voltage, and special-specification oil-immersed transformers still rely heavily on imports, especially products from Chinese, South Korean, Japanese, and European brands.

Local companies mainly assemble and provide after-sales service for small-capacity, low-voltage oil-immersed transformers. The oil-immersed transformer industry maintains rapid growth due to the rapid upgrading of Vietnam's power grid and the expansion of industrial parks.

Import Market Overview

The demand for oil-Immersed transformers is growing in Vietnam, but local production capacity is limited, and the country is highly dependent on imports.

According to analysis, Vietnam's oil-immersed transformer import market is characterized by a high dependence on imports and continuous growth in demand. Driven by increasing electricity demand and rapid expansion of industrial parks, Vietnam's reliance on medium- and high-voltage, high-reliability oil-immersed transformers continues to rise. Medium- and high-voltage transformers with large capacity and high performance have become Vietnam's main import products. The import market is expected to continue to grow in the future, driven by power infrastructure construction and industrial park expansion.

Vietnam's imports of oil-Immersed transformers continue to increase. China is the largest source of imports.

According to statistics, approximately 280 importers in Vietnam imported oil-Immersed transformers in 2024, totaling US$23.84 million, a 46.5% year-on-year increase. According to analysis, Vietnam's total imports of oil-Immersed transformers reached US$23.30 million from January to September 2025, an increase of approximately 30.2% compared to the same period in 2024. China was Vietnam’s the largest import source of oil-Immersed transformers, accounting for approximately 47.1% of total imports from January to September 2025.

Overview of Foreign Investment in Vietnam's Oil-Immersed Transformers Industry

Investment Background

Vietnam's power infrastructure is developing rapidly. With urbanization, industrialization, and manufacturing expansion, the demand for medium- and high-voltage transformers (including oil-immersed transformers) in the power grid has increased significantly. In particular, substation construction and distribution network upgrade projects have created a significant demand for large-capacity, highly reliable oil-immersed transformers. Overall, the large-scale development of Vietnam's power infrastructure, the growing demand for high-efficiency transformers, and Vietnam's reliance on high-quality electrical equipment present significant market opportunities for foreign investment.
