A dry-type transformer is an electrical device designed to lower the incoming voltage of a current to make it easier for electrical devices to withstand high voltage electrical currents. Dry Type power transformers do not use liquids to insulate the windings and core, instead, their design uses a sealed container filled with pressurized air. One of the most common types of dry-type electrical transformer is cast resin. These transformers are well suited for high moisture environments due to the core being insulated in a layer of waterproof epoxy resin.

Single - phase dry type transformer adopts high quality material and advanced technology, it has advantages of damp - proof and convenient maintenance, it can be applied to such power transmission and distribution places like underground railway, high building, airport, station, wharf, enterprise, tunnel, etc. It is mainly used in power supply occasions of AC 50~60Hz and voltage less than 500V. All the input and output voltage , connection group and capacity of tapped winding can be designed and produced according to users' requirements.

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

● Chemical, oil, and gas industry: Dry-type transformers are used to supply power to various equipment and processes that involve flammable or explosive substances, such as refineries, petrochemical plants, pipelines, offshore platforms, etc.

● Environmentally sensitive areas: Dry-type transformers are used to protect the environment from oil spills or leaks that can contaminate water sources, soil, or wildlife habitats, such as water protection areas, forests, wetlands, etc.

● Fire-risk areas: Dry-type transformers are used to prevent fire hazards or minimize fire damage in areas that are prone to fire outbreaks or have strict fire regulations, such as indoor substations, underground substations, hospitals, schools, hotels, shopping malls, etc.

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

● Other applications: Dry-type transformers are also used in other applications that require high performance, low maintenance, or special features, such as traction systems, marine systems, mining systems, data centers, etc.
