ED-2B1 Shackle Insulator — 11kN Porcelain Insulators Product Overview
The ED-2B1 shackle insulator is a porcelain insulator designed for low-voltage overhead distribution lines. It is commonly used as a British Standard type shackle insulator for securing and insulating conductors at terminal poles, corner poles, and tension points.
The ED-2B1 features a compact ceramic body with a height of 76 mm / 3″ and a diameter of 89 mm / 3.5″. With a tensile strength of 11 kN, it provides reliable mechanical support for low-voltage overhead line applications.
Its electrical performance includes a 25 kV dry flashover voltage and a 12 kV wet flashover voltage, making it suitable for dependable outdoor insulation.
The ED-2B1 is similar to the ED-2B model but has a modified inner dimension (d1/d2: 48/17.5 instead of 48/21), which may affect mounting compatibility with certain spindles or brackets. Please verify the required dimensions for your specific installation.
