<p>PROBLEM TO BE SOLVED: To suppress temperature rise of a connection conductor by overlapping the end part of insulation barriers by a predetermined length at the joint thereof and inserting an insulation spacer into the overlapped part to form an oil gap thereby feeding an insulation oil in the insulation barrier to the outer circumferential part. SOLUTION: Insulation barriers 26a, 26b are arranged through a gap on the outside of an insulation layer 15 formed by winding an insulation tape around the surface of a connection conductor 11 while differentiating the diameter and overlapped each other. Insulation spacers 27a, 27b are inserted between the insulation layer 15 and the insulation barriers 26a, 26b with a gap being sustained at a specified value. An insulation spacer 28 is inserted into the overlapped part of insulation barriers 26a, 26b and the insulation spacers 27a, 27b are provided with oil gaps 27c, 28a for passing an insulation oil. The insulation oil at the outer circumferential part of connection conductor 11 and the inner diametral part of insulation barriers 26a, 26b is fed freely in the axial direction to the connection conductor 11 at the part of oil gap 27a and fed to the outer circumference of insulation barrier at the oil gap 28a.</p> |
