Description of preformed insulator tie

Preformed insulator tie also named distribution tie,the insulator tie 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, single 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.

Material of distribution tie

Aluminum-clad steel with an elastomer pad
