<p>PURPOSE: To provide an interphase spacer capable of previously preventing dielectric breakdown, using a polymer insulator in an insulator body. CONSTITUTION: An interphase spacer 1 has a bending detecting component 2 capable of detecting a bend exceeding a tolerance limit of a polymer insulator 5, from the external appearance later on. Since the bend exceeding a tolerance limit of the polymer insulator 5 is detected on the ground or from a helicopter or the like later on, before the interphase spacer 1 causes dielectric breakdown, measures such as the replacement of the interphase spacer 1 are made possible.</p> |
