Double line ties /top ties are intended for securing bare conductors into the top groove of insulators. On vertically-mounted insulators at double crossarms or brackets, the double line ties /.top ties can normally accommodate line angels of up to 20 degree with no more than a 10 degree angle at each insulator.
Mechanical: Double line ties/top ties will develop unbalanced and lift-off loads equivalent to , or in excess of, a hand tie over covered conductor. When installed with a pad on bare conductor, double line ties/top ties provide superior protection against abrasion and all types of conductor motion. The pad is a resilient cushion at the point of contact between conductor and insulator.
