Abstract

PURPOSE:To increase the quality of an oil filled electric apparatus by narrowing the end section at the winding wide of a shielding conductor than the other section wherein a lead wire and a connection lead wire are inserted in the conductor and high dielectric strength is made possible. CONSTITUTION:A lead wire 1 and a connection lead wire 2 are covered with a pipe-shaped shielding conductor 6. Insulation coating 7 is applied to the conductor 6 and the conductor 6 and the lead wire 1 is are also maintained at the same electric potential. Furthermore, the end section of the conductor 6 have a cone- configuration or the like which narrows the tip and an insulator is wound at the end section 9 of the conductor 6 to cover the tip. An oil-proof insulator 8 is also provided around the conductor 6 locating at the lead wire section. In this way, the tip of the conductor will not touch with several sections of the windings as the tip of the conductor 6 is narrow and the insertion to the opening section of the insulator 8 will also be facilitated and high dielectric strength will be permitted by shortening assembly hours and by preventing moisture absorption.
