The high-voltage coil of this dry-type transformer is fabricated with metal conductors such as copper and aluminum. These conductors are also covered with class F insulation that can withstand up to 155 degrees Celsius. The insulation is made of resin with reinforced glass fiber. The expansion coefficient of both glass and fiber is almost similar, thus, this could reduce the chance of coil breaking when operating the transformer at high temperatures.
