Oil-immersed transformer

Oil-immersed transformers are one of the key devices in power systems, and their working principle is based on electromagnetic induction to achieve voltage transformation. The core components are immersed in insulating oil to achieve insulation and heat dissipation. This type of transformer features a compact structure, stable operation, and convenient maintenance. Its length can vary depending on capacity and model, generally customized according to actual needs. In power transmission and distribution, oil-immersed transformers play a crucial role in ensuring the safe operation of the power grid. Additionally, their height and width may also be adjusted based on power and design to meet the application needs of different scenarios.

We aim to contribute to the vigorous development of the new energy industry and work together to power a better future!

Dry transformer

Dry-type transformers are a special type of electrical device designed for efficient voltage conversion to meet the needs of different electrical equipment. Its main feature is the absence of oil as an insulating and cooling medium, hence the name 'dry-type'. This type of transformer typically has good heat dissipation performance and high safety, allowing it to operate at higher temperatures without danger. The length of dry-type transformers varies depending on the model and application, with some being only a few meters long while others can reach several dozen meters. These transformers are widely used in residential, commercial, and industrial facilities, providing stable power supply for various devices.

American-style box transformer

The American-style wind power box substation seals the high-voltage load switch, fuses, high-voltage components, transformer body, and no-load tap changer in the same oil chamber. The structural product integrates the advantages of European and American transformers and is a new type of boosting device specifically designed for the uniqueness of wind power. It has strong completeness, easy installation, short construction period, low operating costs, high structural strength, strong corrosion resistance, and is environmentally friendly and energy-saving. It is suitable for operating environments with harsh natural conditions such as beaches and deserts. This product is used in various wind power generation sites and is a supporting product for wind power generation systems that combines collectivity, safety, practicality, and economy.

European-style box transformer

The YB series substations, commonly known as European-style transformers, are compact integrated distribution devices that combine high-voltage electrical equipment, transformers, and low-voltage electrical equipment. They are used in urban high-rise buildings, urban and rural areas, residential communities, high-tech development zones, small and medium-sized factories, mining oil fields, and construction sites for the purpose of receiving and distributing electrical energy in power distribution systems.

Medium voltage components

Medium voltage components refer to electrical components with a rated voltage between 1kV and 35kV. They play a critical role in power systems, used for controlling, protecting, and distributing electrical energy. With the rapid development of smart grids and renewable energy, medium voltage components are evolving towards intelligence, modularity, high reliability, and environmental friendliness. In the future, medium voltage components will focus more on integrating with digital technology and IoT technology to achieve functions such as remote monitoring, fault warning, and intelligent diagnosis, thereby improving the operational efficiency and safety of power systems.
