Transmission bundle blocks
Transmission class line construction is very specialized. Terrain, spans, structures and pulls are all larger and the conductor can require a plethora of construction configurations. The configurations can range from single to bundles of two, three, four or six per phase. For all these reasons, the configuration and quality of the blocks which interface with the conductor are of the utmost importance.
