In a bustling yet orderly industrial park's shipping platform, a colossal object is being carefully loaded onto a specially designed heavy-duty truck.

A grading ring, also known as a voltage equalizing shielding ring, is a large metal ring installed at both ends (or one end) of the insulator string in high-voltage Transmission lines (typically 220kV and above). Its main function is to improve the electric field distribution around the insulator string, prevent local corona discharge and arcs, thereby protecting the insulators and fittings and ensuring the safe and stable operation of the line.
