Anti-Corona Shield Solutions
Our Grading Ring Assembly HINGE SIDE adpoted aerospace-grade 6061-T6 and 6101-T4 aluminum alloy, which achieves an optimal balance in terms of electrical conductivity (32.5 MS/m), corrosion resistance (passing the ASTM B117 1000-hour salt spray test), and machinability.
Our CNC bending machine is adept at executing multi-angle bends and fabricating bent pipes with intricate and challenging configurations.
When dealing with large-diameter, thin-walled pipes,a mandrel must be inserted to provide internal support for the pipe, thereby preventing any deformation during the bending process
Our core expertise lies in solving the fundamental challenge of electric field non-uniformity through industrial-scale production of grading rings, which homogenize electric fields to eliminate corona discharge, power losses, and equipment degradation.
Where necessary,suitable shields protect the main circuit form the corona effect
