Abstract

PURPOSE:To easily simplify the assembling and testing works of an oil-filled electric device and reduce the number of steps in the works by gas insulating a cable connection box for connecting the lead terminal of the device to the end of a cable. CONSTITUTION:SF gas is sealed in a cable connection box 8 fixed to an oil-filled electric device external box 2. A lead terminal 3 introduced from a content 1 is connected to the end 6 of a cable 5 via a connecting lead wire 7 in the cable connection box 8. In this manner, the assembling and testing works can be remarkably easy. That is, SF6 gas can be extremely easily sealed and recovered as compared with insulating oil. Since no insulating work such as taping or the like is not necessary when connecting and disconnecting the connection lead wires, the works becomes easy.
