Product Introduction:

Cast Resin Dry Type Transformers are fabricated using a high grade insulating material known as epoxy resin and here the windings are encased. This material, when hardened, forms the body of the transformer. It provides exceptional insulation, enhances durability and minimizes the risk of fire hazards. This type of transformer is known for its safety and reliability, particularly in environments that require a high level of safety such as high rise buildings, hospitals, shopping malls, airports and more.

The transformer is referred to as dry type because it does not use any liquid type of coolant such as oil, hence the term dry. Instead, the cooling is done through natural air or artificially the transformer is equipped with fans and air is flown into it.In terms of construction, the primary and secondary windings are wound with conductive wire, just like in other types of transformers. The manufacturing process involves the winding being placed in a mold, after which the epoxy resin is poured in. The resin hardens, creating a solid, robust and well insulated winding.

A basic overview of these type of transformers can be mentioned as under:

1.The windings are made of copper or aluminum conductors, which are insulated with epoxy resin. The resin helps to provide solid insulation and enhances the strength of the windings.
2.In cast resin transformers, the core and windings are cooled by air conduction. The windings are encased in epoxy resin, which has excellent heat dissipation properties, allowing the heat produced during operation to be effectively transferred to the ambient air.
3. Since they do not use flammable coolants like oil, these transformers pose less of a fire risk. This makes them ideal for use in areas where fire safety is a major concern, such as residential buildings, hospitals, and schools.
4.Cast resin transformers require less maintenance compared to oil filled transformers. They do not need to be periodically checked for coolant leaks, making them a more cost effective option over their lifespan.
5.As they do not use oil, there is no risk of soil or water contamination in case of a leak. This makes them a more environmentally friendly transformer option.
6.These transformers are widely used in places where safety is of utmost concern and in areas that have strict environmental regulations. They are commonly used in indoor and outdoor applications, renewable energy systems, industrial plants and commercial buildings.

Technical Specifications & Industry Nomenclature

Our cast resin dry type transformerrepresents the pinnacle of safety and reliability for indoor power distribution. Frequently referred to in the industry as a CRT (Cast Resin Transformer)or an epoxy cast transformer, these units are engineered using a vacuum casting process that encapsulates the windings in a high-grade resin mix. This ensures the unit is virtually maintenance-free and highly resistant to moisture, dust, and environmental contaminants. Known also as a fire-retardant transformer, it is the preferred choice for high-rise buildings, hospitals, and underground metros because it is self-extinguishing and does not pose the leakage or fire hazards associated with oil-filled units.

Technically, our VPI (Vacuum Pressure Impregnated)and cast resin designs are classified as non-hygroscopic transformers, meaning they do not absorb moisture even after long periods of shutdown. Depending on the installation site, they are often called indoor dry type transformersor enclosure-protected transformerswhen housed in IP-rated steel cabinets. These units are built to withstand high thermal shocks and feature a high mechanical strength in the windings to resist short-circuit forces. Whether you are looking for a cast resin distribution transformerfor a data center or a specialized dry type isolation transformer for sensitive medical equipment, our products meet the highest F1 (Fire Integrity), E2 (Environmental), and C2 (Climatic) international standards.
