Do towers need extra load tolerance or other modifications to install SkyWrap?
No, installation of SkyWrap only increases the host conductor weight by about 15kg per 300m (35lbs per 1,000ft) span which is well within the capacity of most towers. SkyWrap does not affect the ground clearance of existing lines so no modification to existing structure is required. If necessary, a tower strength analysis could be carried out prior to installation to ensure that the 300kg (660lbs) all-up weight of the installation equipment is acceptable. AFL can assist with these studies.
