Description

DETAILED DESCRIPTION OF THE INVENTION This invention branches into a plurality of circuits from the opening/closing dκ of an air switch on a stand within a limited nuveine on a pillar, etc., and crosses these branch lines. To provide a multi-branch wiring method that facilitates wiring work without causing contact and also takes into consideration the aesthetics of urban areas and the installation of pillars.

Hereinafter, one embodiment of the present research will be described with reference to the drawings.A vertical air switch 3 supported on a utility pole 1 via a support fitting 2 as shown in FIG. To,
Load 11111 (left side in the figure) and power supply side (fu

In contrast, it consists of a supporting part 15 with a new U-shaped face and a pressure member 16 attached to the outer surface of the supporting part 15 with bolts. As shown in Figure 1, each terminal is covered with a terminal cover 17, 18, 19. Therefore, the connection terminals 10, 11.12 for each phase each have three crimp parts (16th.

2zb and 22c are branched and pulled down to load-side power distribution equipment (in this embodiment, jumper switches 23, 24, and 25), which will be described next.

That is, in the case of branching into three circuits.

The vertical air switch 3 is supported by the utility pole 1 in the upper direction.
