ANSI-Standard High-Voltage Compatibility: The 52-3 porcelain suspension insulator complies with ANSI C29.1/C29.2 standards, with a rated mechanical load of ≥70kN and a power frequency breakdown voltage of ≥110kV, specially engineered for 35-110kV power transmission lines.
Universal Connection Design for Enhanced Installation Flexibility: It adopts a dual-compatible connection structure of ball-and-socket and clevis-and-tongue, meeting the adaptation needs of different transmission towers and conductors. This design streamlines the installation process and reduces reliance on special hardware.
High-Quality Ceramic Material: Made of high-strength electrical ceramic with a uniform glaze finish, the porcelain disc features low contamination adhesion on the surface, which effectively prevents arc creepage and ensures stable insulation performance.
