Product Description

Metal double line tie/ top tie



Metal double line tie /top tie are intended for securing bare conductors into the top groove of insulators. On vertically-mounted insulators at double crossarms or brackets, metal double line ties/ top tie can normally accommodate line angels of up to 20 with no more than a 10 angle at each insulator.  

Material: Aluminum-clad steel with an elastomer pad

Mechanical: Metal 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.

Insulators: Φ57mm (C Neck), Φ73mm (F neck) and Φ89mm (J neck)

Applicable conductor: ACSR, All-Aluminum, Aluminum Alloy and etc ...
