PURPOSE: To shorten the length of a leader bus-bar by tilting the leader bus-bar, which is for connecting a switchgear formed of breaker, disconnectors, earth connecting switches, etc., to the other equipment, in a vertical direction toward a leadout part of the other equipment.

CONSTITUTION: A bus-bar 4 is connected to the other equipment, for instance, transformer 5 through a compound switchgear formed of two or more disconnectors 2, earth connecting switches 3 and breakers l. A leader bus-bar 8 between the compound switchgear and the transformer 5 is tilted in a vertical direction toward a leadout part 9 of the transformer 5. The leadout part 9 is so provided as to agree with an extending direction of the bus-bar 8. In this way, a required amount is decreased by decreasing the length of the leader bus-bar 8.
