Custom Grading Ring Metal Fabrication for High-Voltage Electrical Equipment
A grading ring is a power line hardware component used to optimize electric field distribution. It is formed by bending tubular material into a circular ring structure, providing excellent ring stability and the ability to evenly regulate the electric field. The inner side of the product features an open-type clamp structure that is secured with bolts at both ends, enabling convenient installation and reliable fastening.
The annular design effectively mitigates localized electric field concentration while maintaining a simple structure and stable installation, thereby meeting the requirements for electrical performance and mechanical reliability in high-voltage electrical systems.
