Overview

As the global demand for energy increases, so does the need for high-temperature transformers. Today, state-of-the-art computer programs have extracted about as much cost as possible in pursuit of competitive designs. High-temperature, liquid-immersed transformers represent one of the few opportunities available for longer life, increased capacity, and/or smaller size. While high-temperature design has been around for many years, its use has been limited by the high cost of insulation and the lack of standards governing high-temperature applications. Now the standards are in place and available to shape development in this area. The logical next step is the development of materials to take advantage of these standards. This presentation will look at a new high-temperature insulation concept for liquid-immersed transformers. Built around DuPont Nomex®, the engineered cellulose insulation can be used to deliver improved transformer life or improved overload capability.
