Brief
ED-2 upgraded butterfly insulator has higher mechanical bearing capacity than ED-1. It is suitable for large-span low voltage lines and foreign engineering bulk orders.
Material
Thickened electrical porcelain, hot-dip galvanized metal fasteners.
Function
Strain insulation for large-span low voltage lines, bear stress insulation for corner and terminal stay wires.
Features
Higher bearing capacity, strong tensile resistance, crack resistance and ultra-high cost performance.
Application
Rural low voltage main lines, factory low voltage wiring and long-distance overhead stay wire projects.
