Description
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
Insulators of insulator tie
Φ57mm (C Neck), Φ73mm (F neck) and Φ89mm (J neck)
Applicable conductor of preformed tie
ACSR, All-Aluminum, Aluminum Alloy and etc …
Fixed insulator line post neck C neck Φ57mm
