摘要

Tape-wrapped joints have been mostly used in high voltage (6600V) power supply cabling system for Tunnel Boring Machines at tunnel construction site. It requires certain skills, workmanship and the joint assembly is time consuming. To meet the demands of shortening and simplifying the joint assembly time at the site, we have developed the 6600V cable joint connector using a pre-molded-insulator and cable handling system. We have succeeded in realizing cost down, short assembly time and simplifying of the joint assembly. This report describes the development of a high voltage power supply system. This new system produced actual results in the mountainous Hida tunnel and the Shimura-Sakashita utility tunnel at an urban under ground site.
