<P>PROBLEM TO BE SOLVED: To provide a bushing protective terminal for surely protecting porcelain bushing from an external force caused by an earthquake. <P>SOLUTION: A bushing protective terminal comprises: a first conductive substrate 11 fixed to a conductive shaft 8 which extends outward from a terminal part of bushing 4 in an axial direction and to which a wire 108 is connected; a second conductive substrate 12 which is provided oppositely to the first conductive substrate 11 and fixed to the conductive shaft 8; an extendable and contractable flexible wire 13 for electrically connecting the first conductive substrate 11 and the second conductive substrate 12; and a breaking setting section 18c provided on the conductive shaft 8 between the first conductive substrate 11 and the second conductive substrate 12 and comprised of a conductor that can be broken down by a tensile force, caused by an earthquake, of a predetermined value or more exerted on the wire 108. <P>COPYRIGHT: (C)2012,JPO&INPIT |
