A cast resin dry type transformer (CRT) is a type of transformer that uses epoxy resin to encapsulate its primary and secondary windings. This protects the windings from moisture, dust, corrosion, and other environmental factors that can affect their insulation and performance.
A CRT is suitable for high humidity areas, indoor installations, and fire-risk areas because it is non-hygroscopic, non-inflammable, and maintenance-free. It can also withstand overloads, partial discharges, and low losses, resulting in high efficiency and long service life.
A CRT is available in ratings from 25 kVA to 12,500 kVA, with insulation class of F (90°C temperature rise).

750 kva dry type transformer
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.
