New trend on transmission power lines and related stringing equipment development

The new trends of major transmission networks & UHV Power Lines require machines specifically designed: objective of manufacturers is to design and manufacture transmission stringing equipment able to face the new demand in large crossing stringing operations, without damaging the conductors of new generation and maintaining at the same time the maneuverability of the machines. Innovation has been carried out also in materials: the use of hard materials for the bull-wheels grooves surface does not affect the conductor's surface allowing a smooth stringing behavior of the conductor. The need to perform vicinity works with the highest possible safety level generates a new package of traction machine and cradle blocks, mainly used for OPGW replacement activities with energized line, but also used to install protections nets or to create protection corridors over critical crossings.
