目的とする。SUMMARY OF THE INVENTION Conductor 2b and bolt 1b
If the aqueous solution S containing an electrolyte such as rainwater adheres to the outside of the contact area with the zinc, the zinc of the plating layer of the bolt 1b will first be corroded due to the contact corrosion (electrolytic corrosion) by the dissimilar metal, and then the bolt base material. When the iron appears, the bolts will be rapidly corroded. Therefore, the service life of the conductor connecting portion is determined by the thickness of the zinc plating. The thickness of this hot-dip galvanized layer is about 100 μm at maximum,
There is a problem that the thickness of the conductor connection part of the outdoor electric equipment is limited to its useful life. Therefore, an object of the present invention is to easily increase the thickness of zinc to obtain a longer service life.
