The left end of the enclosed container 1 is closed by a closing board 18a while the right end thereof is closed by a closing board 18b. The closing board 18a is provided with two openings 40a, 40b vertically which are coupled through insulation spacers 36 with main buses 12a, 12b respectively. The closing board 18b is provided with openings 40c, 40d vertically, where the opening 40c is coupled through an insulation spacer 36 with a line side terminal section 17 while the opening 40d is an inspection opening and normally covered by an end cover 19.</p> |
