ANSI 54 Series 11kV 33kV Stay Insulators

ANSI 54 Series insulators are a type of stay wire insulator used in overhead distribution and transmission lines. Depending on the specific model, they are suitable for lines from 0.4kV up to 33kV, providing reliable mechanical support and electrical insulation for stay wires on poles and towers.

Typical models include ANSI 54-1, 54-2, 54-3, and 54-4, each designed to accommodate different line tensions and pole configurations. In practice, ANSI 54-2 is commonly used on 11kV lines, and is therefore often referred to as the 11kV stay insulator, while ANSI 54-4 is widely used on 33kV lines, earning the designation 33kV stay insulator.
