<P> Transformer oil 's primary functions are to insulate and cool a transformer . It must therefore have high dielectric strength , thermal conductivity , and chemical stability , and must keep these properties when held at high temperatures for extended periods . Typical specifications are : flash point 140 ° C or greater , pour point − 30 ° C or lower , dielectric breakdown voltage 28 kV ( RMS ) or greater . </P>
