PURPOSE:To prevent the degradation of dielectric strength due to a minute oil clearance by forming one part of insulation at the intermediate section of the lead wire with the intermediate section divided into two sections when transport by the continuous insulating layer with other sections of the lead wire. CONSTITUTION:When an apparatus formed by connecting parts such as a transformer coil 1 and a bushing 2 by the lead wire 3 is divided into two sections at the intermediate section B when transport and assembled again at sites conductors 5a, 5b are connected through connecting terminals 6a, 6b, and the second insulator 7c is taped between the first insulators 7a, 7b. The continuous insulating layer 9a is formed through taping extending over a section B connected and the other sections of the lead wire 3. Accordingly, the minute oil clearances are not shaped at the connecting section, and dielectric strength and mechanical strength can be improved. |
