In the early 1970s public pressures for aesthetically
pleasing transmission lines led to the development of
several compact link concepts, one of which was built
near Toronto. The new designs were based on shorter
strings of semiconducting glaze insulators and tl:.e
anticipated success of a novel galloping control
method. During the late 1980s the need to reconductor
and upgrade lines within narrow rights-of-way renewed
interest in compact lines. A 40 year ·old 115 kV
lattice tower was redesigned to carry a laq;er
conductor at 230 kV. The.principal innovation used is
the horizontal vee insulator in place of the tower
arms.
