Zusammenfassung
erhead transmission lines, it is quite important to
prevent accidents caused by galloping and sleet jump
phenomena of snow and/or ice covered conductors since the
accidents sometimes may lead to phase-short circuit and also
mechanical failures of conductors and/or insulator
assemblies.
It has been known that phase-to-phase spacers are quite
effective but the practical application is quite limited to
transmission lines of 77 kV and below so far, since there
are ~any technical subjects to be solved.
Under such a circumstance, we challenged to study on
possibility in further application of The spacers and
developed the 275 kV spacer and established rational desing
concept for the spacer for 275 kV transmission lines.
