Material:
PVC plastic double top ties are made from white PVC.This material was selected for UV resistance,tensile strength,impact strength, flexural strength and self-extinguishing properties.
Mechanical: PVC plastic double top ties will develop unbalanced and lift-off loads equivalent to,or in excess of, a hand tie over covered conductor.
Insulators: Φ57mm (C Neck), Φ73mm (F neck) and Φ101.6mm (K neck); PVC plastic single line/top ties are used with either ANSI compliant polymer or porcelain insulators.
