A dry-type transformer is an electrical device designed to lower incoming voltage, making it suitable for electrical devices to withstand high-voltage currents. Unlike traditional transformers, dry-type power transformers do not use liquids to insulate the windings and core. Instead, they use a sealed container filled with pressurized air. One of the most common types of dry-type transformers is the cast resin transformer. These transformers are well-suited for high-moisture environments because the core is insulated with a layer of waterproof epoxy resin.

The single-phase dry-type transformer is made of high-quality materials and advanced technology. It offers advantages such as being moisture-proof and easy to maintain. It can be used in power transmission and distribution settings like underground railways, high-rise buildings, airports, stations, docks, enterprises, tunnels, and more. It is primarily designed for power supply applications with AC 50~60Hz and voltage less than 500V. Additionally, the input and output voltage, connection group, and tapped winding capacity can be customized according to user requirements.

Dry-type transformers are widely used in various industries and applications that require high safety, reliability, and environmental compatibility. Some common applications of dry-type transformers include:

● Chemical, Oil, and Gas Industry: Dry-type transformers supply power to equipment and processes involving flammable or explosive substances, such as refineries, petrochemical plants, pipelines, and offshore platforms.

● Environmentally Sensitive Areas: Dry-type transformers are used to protect the environment from potential oil spills or leaks that could contaminate water sources, soil, or wildlife habitats, such as in water protection areas, forests, and wetlands.

● Fire-Risk Areas: Dry-type transformers help prevent fire hazards or minimize fire damage in areas prone to fire outbreaks or with strict fire regulations, such as indoor substations, underground substations, hospitals, schools, hotels, and shopping malls.

● Renewable Generation: Dry-type transformers are used to connect renewable energy sources, such as wind turbines, solar panels, and hydroelectric plants, to the grid or load.

● Other Applications: Dry-type transformers are also utilized in applications requiring high performance, low maintenance, or special features, such as in traction systems, marine systems, mining operations, and data centers.
