According to a new report published by Allied Market Research titled, “Cast resin dry type transformer market by Type, Cooling Type, Phase, Voltage, and End Use: Global Opportunity Analysis and Industry Forecast, 2021–2030,” the cast resin dry type transformer market size was valued at USD 3.0 billion in 2020, and is projected to reach USD 5.0 billion by 2030, growing at a CAGR of 5.3% from 2021 to 2030.
Cast resin dry type transformers are magnetic core transformers that use air, rather than oil or other liquids, as a cooling medium. In these transformers, both the high-voltage (HV) and low-voltage (LV) windings are vacuum-cast in epoxy resin, fully sealing them against moisture and offering superior fire protection. This makes them ideal for indoor applications, especially in underground or urban substations where fire safety is critical.
Compared to traditional oil-filled transformers, cast resin dry type transformers offer several key advantages. They are easier to install, require minimal maintenance, and provide strong resistance to short-circuit currents and overloads. Their design eliminates the need for environmentally hazardous liquids, making them eco-friendly and pollution-free. Additionally, their self-extinguishing properties reduce the need for extensive civil works and fire protection systems.
These benefits have led to rising demand for cast resin dry type transformers across industrial, commercial, residential, and infrastructure projects, particularly in areas where safety, sustainability, and compact installation are priorities.
