Abstract
The history in the development of 500kV XLPE cable, especially the struggles in the development work and field application by the engineers has been described in this article. Power cables are one of the large-sized industrial products; however, 500kV XLPE cable requires very sophisticated and fine technologies in its realization. On the way to the goal of its realization, engineers had many struggles against never-experienced subjects and finally they could overcome such difficulties. Field application of 500kV XLPE cable, including installation and jointing, had been established based on the much effort of many engineers.
