てはならないことがある。However, the construction method in this case has a drawback that the assembling work on site is more troublesome than the conventional switchboard using air insulation. For this reason, the busbars are made into cables or have mold insulation, and gas filling work is omitted in the connection between the boxes that house high-voltage equipment, but even in that case, the necessary space for cable end processing cannot be secured. In some cases, it may be necessary to remove even the busbars that do not need to be removed due to restrictions on the attachment / detachment order.
