ANSI 52-1, 52-2, 52-3, and 52-4 porcelain disc suspension insulators manufactured to ANSI C29.2 standards.
High mechanical strength, reliable insulation performance, and long service life for transmission and distribution lines.
ANSI 52 Series Disc Suspension Insulators are cap-and-pin type porcelain insulators designed according to ANSI C29.2 standards.
They are widely used on overhead transmission and distribution lines to provide electrical insulation and mechanical support for conductors.
The different ANSI classes mainly differ in mechanical strength, creepage distance, and electrical performance.
