品コストの低廉化を阻んでいた。As shown in Figure 6, the heat dissipation fins of transformer cases in the United States are retrofitted by forming a large number of separate parallel heat dissipation parts at appropriate intervals on the smooth circumferential surface of the body, and by drilling holes inside. The transformer is cooled by circulating the coolant inside the case through the provided upper and lower holes. This configuration of the heat dissipation section requires a large number of manufacturing steps, a long production time, and is difficult to mass-produce, thus hindering reductions in product costs.
