ANSI 55 Series Pin Type Insulators

ANSI 55 Series pin type insulators are designed for reliable mechanical support and electrical insulation in medium-voltage overhead distribution lines. These insulators are made of high-quality porcelain, ensuring excellent resistance to electrical stress, weathering, and pollution, making them ideal for harsh outdoor conditions.

Common models in the ANSI 55 series include ANSI 55-3, ANSI 55-4, and ANSI 55-5, each rated for different voltage and mechanical requirements to meet the diverse needs of power distribution networks. The insulators are suitable for mounting on cross-arms with galvanized steel pins, providing secure attachment while maintaining long-term performance.

These pin-type insulators comply with ANSI standards, ensuring safety, reliability, and durability in medium-voltage line applications. They are widely used by utilities for distribution lines and other electrical infrastructure requiring robust insulation and mechanical stability.
