1. Introduction to Hydropower Transformers
Hydropower transformers are specialized step-up transformers used in hydropower plants. They are ones of the most important electrical devices in hydropower projects in Vietnam today.
2. Characteristics of Hydropower Transformers
2.1. Seasonal Characteristics
Since hydropower plants operate with seasonal variations in water flow and power output, Vintec hydropower transformers are specifically designed for intermediate substations in small and medium-sized hydropower plants. These transformers often operate under overload conditions during peak seasons.
During the rainy season, to maximize power generation, transformers typically operate at 130% – 150% of their rated capacity for 3 to 4 months without exceeding permissible temperature limits.
Therefore, the design and manufacturing of hydropower transformers require a robust structure, effective oil circulation, and superior heat dissipation.
2.2. Location Characteristics
A hydropower transformer is usually installed in mountainous regions with frequent heavy rains and lightning strikes. Due to these conditions, Vintec transformers are designed with the following outstanding features:
High-capacity power transmission, reducing energy losses during transmission and distribution.
Energy efficiency of up to 99.44%, ensuring continuous and stable 24/7 operation for optimal power system performance.
Constructed from high-quality, eco-friendly materials for durability and impact resistance.
Manufactured with precision using advanced machinery and an experienced engineering team, following strict quality control processes to ensure top-tier safety during operation.
Extremely low noise levels, strong short-circuit resistance, high lightning protection, and excellent long-term overload capacity.
Thanks to these outstanding features, Vintec hydropower transformers are the top choice for hydropower projects in Vietnam today.

3. Why Use Hydropower Transformers?
As outlined in Section 2, the seasonal and geographical characteristics of hydropower plants necessitate specialized transformers with high durability, low noise, strong short-circuit resistance, excellent lightning protection, and long-term overload capability.
4. Testing of Hydropower Transformer
Transformer testing is a mandatory step in the manufacturing process and must comply with strict regulations set by the electricity sector. Vintec Group adheres to these standardized testing procedures for all products before delivery to customers.
Hydropower transformer play a critical role in power plants. Therefore, thorough and rigorous testing is essential before operation to prevent system-wide failures caused by transformer malfunctions.
5. Storage and Transportation of Hydropower Transformer
Vintec provides comprehensive support for transportation and proper storage of transformers before integration into the power grid, ensuring the best product quality upon installation.
5.1. Transformer Storage:
Store in a dry area before use.
Protect ceramic components from impacts that could cause cracks or breakage.
Preferably, store the transformer in a covered warehouse.
Maintain adequate spacing between transformers to prevent damage to cooling fins and other accessories.
5.2. Hydropower Transformer Transportation:
Always keep the transformer upright; tilting is not allowed.
Secure the transformer firmly to prevent movement during transport, avoiding straps on corrugated cooling fins and insulators.
When transported by truck, Vintec ensures a speed limit of no more than 30 km/h.
6. Where to Buy Hydropower Transformer?
In addition to its main product lines, such as solar power transformers, high-frequency furnace transformers, single-phase oil transformers, and three-phase oil transformers, Vintec Group also focuses on manufacturing high-quality hydropower transformer. Vintec hydropower transformer is the top choice for large, medium, and small hydropower projects in Vietnam.
With nearly 20 years of experience in manufacturing power transformers, Vintec has firmly established itself as a key player in the industry, contributing to the growth of Vietnam’s power sector.
