A mounting construction of a tank-type lightning arrester for a neutral point of a transformer includes a transformer having a transformer winding contained within a transformer tank, the transformer winding having a neutral point, and a tank-type lightning arrester having an overvoltage protection element contained within a lightning arrester tank. A first opening is formed in an upper portion of a side surface of the transformer tank, and a second opening is formed in the lightning arrester tank, and the first and second openings are connected together through an insulating spacer having a central conductor, and the neutral point of the transformer winding is connected to the overvoltage protection element via the central conductor. The lightning arrester tank is supported solely by a mounting portion provided on a side surface of the transformer tank.
