PURPOSE:To minimize the length of high tension conductor and to make the maintenance, inspection and construction of the switchbox easy by providing a high voltage disconnecting switch to the ceiling of switchbox and by collecting the conductors in the upper space of switchbox. CONSTITUTION:The disconnecting switch 21, which connects the primary terminal 26 of transformer 20 of the spot network receiving unit with the cable head 22, is provided to the ceiling 15 of the switchbox 10 above the primary terminal 26, cable head 22 and connecting part of the high tension conductors. Therefore the length of connecting conductor 28 between the primary terminal 26 of transformer and the cable head 22 can be minimized and easily connected. The size of switchbox 10 can be made less, and the maintenance, inspection and construction of switchbox can be made easy. |
