In an amorphous core transformer, an amorphous core is constructed such that, when a plurality of kinds of amorphous magnetic strips having different widths are arranged in abutting relation and laminated, the amorphous magnetic strips are alternated in arrangement for lamination so that abutting surfaces of the arranged and laminated amorphous magnetic strips are displaced with respect to one another. Thus, hours of wrapping work are drastically reduced and working efficiency is improved.

The present invention aims to provide a stationary equipment installed in a sealed space on a space-saving basis and having a favorable cooling efficiency. The stationary equipment includes an equipment main body containing an iron core, a coil and insulating oil, a hollow pipe connected to the equipment main body to circulate the insulating oil in it and a plurality of hollow corrugated fins disposed on the pipe. The pipe and the corrugated fins are covered with a hood, a duct is connected to the hood and the duct is connected to an elongated cylindrical member vertically disposed on an inner wall of the tower to increase airflow by stack effect to increase a cooling efficiency in a wind power generation device.
