Development of Section Insulator for High-speed Passage with Power ON


Tadashi KOHIDA, Hiroki NAGASAWA
To cope with an increased train load on BT section of narrow-gauge lines, it bacame necessary to add a new resistance section to the existing BT section. It is necessary for the new section to be able to permit high-speed passage of train with Power ON. A series of new section insulators have been designed and developed. In order to confirm practical applicability of such an insulator section, laboratory and field tests have been carried out successfully.
