Summary: | The present invention relates to a method of manufacturing a dry type transformer (1000). In particular a method of manufacturing a dry type transformer (1000) with a heat pipe evaporator (101) is provided with the steps of providing (801) a hollow cylindrical heat pipe evaporator (101), winding (802) at least one high voltage coil (112, 120) onto the heat pipe evaporator (101) around a longitudinal axis (110) of the heat pipe evaporator (101), and placing (803) an at least one low voltage coil (113) such that the heat pipe evaporator (101) is positioned between the at least one high voltage coil (112, 120) and the at least one low voltage coil (113). The heat pipe evaporator (101) is adapted to remove heat from the at least one high voltage coil (112, 120) and from the at least one low voltage coil (113), and is adapted to dielectrically insulate the at least one high voltage coil (112, 120) from the at least one low voltage coil (113). |
