4.44 lb Corona Ring
A corona ring is a conductive grading device installed on high-voltage transmission and distribution line fittings to control electric field intensity. By equalizing voltage stress at critical connection points such as insulator strings, clamps, and terminations, the corona ring minimizes corona discharge, radio interference, and premature insulation degradation. It is an essential component for improving the reliability, efficiency, and service life of overhead power line infrastructure.
Key Features
Electric Field Control: Reduces localized electric field concentration at high-voltage points.
Corona and RIV Suppression: Minimizes corona discharge, audible noise, and radio interference voltage (RIV).
Enhanced Insulation Performance: Protects insulators and fittings from surface erosion and aging.
High-Conductivity Materials: Typically manufactured from aluminum or aluminum alloy for optimal performance and corrosion resistance.
Optimized Geometry: Smooth, circular profile ensures uniform voltage distribution.
HV and EHV Compatibility: Suitable for high-voltage and extra-high-voltage transmission lines.
Long Service Life: Designed for outdoor exposure, mechanical stability, and minimal maintenance.
