as a fire barrier. When used as a wetting agent, the concentrate lowers the surface tension of the water, allowing better penetration into deep seated fires. As a fire barrier, Class A foams increase moisture con-tent in Class A combustibles, preventing the ignition of these type fuels. When used as a fire barrier, airDIELECTRIC FLUIDS FOR TRANSFORMER COOLINGof the tank, where the fluid is at its highest or top oil temperature, it exits the main tank and enters a series of radiators or cooling fins. It then flows downward through the radiators, where it is cooled, and reenters the main tank at the bottom. In self cooled transformers this cycle
