The aluminum corona shielding sphere, also known as a corona shielding ball, is used for 460kV terminal bushings on power transformers and is primarily made from aluminum alloy.
Typically, aluminum corona shielding spheres and rings are polished to a bright finish to achieve a smoother, burr-free surface, ensuring optimal corona shielding performance.
These shielding spheres are designed for alternating current (AC) voltage systems and work by evenly distributing high voltage around the object, preventing potential differences (PD) between different parts of the spheres.
If you’re concerned about the design outcomes when working with Chinese manufacturers on aluminum corona shielding spheres, you’ve come to the right place. Let’s dive into finding the best solutions for designing aluminum corona shielding spheres and balls for 460kV terminal bushings.
Aluminum Corona Shielding Sphere New Mould Design
If a client’s inquiry for an aluminum corona shielding sphere matches an existing diameter and size, the process is straightforward.
There’s no need to spend additional time on designing and developing a new mold. However, if the corona shielding sphere’s outer diameter is customized or if a matching mold isn’t available in stock, a new mold will need to be designed and developed.
For standard molds that we have in stock, there is no additional charge. But if a custom mold is required, additional design work and fees will apply.
The mold for an aluminum corona shielding sphere refers to the tooling used to shape the sphere during the manufacturing process.
Choosing The Right Raw Materials For Aluminum Corona Shielding Sphere Design
It depends on aluminum corona shielding sphere design and applications.
The customized outer diameter aluminum corona shielding spheres are usually made from 6061 or 6063 aluminum alloy that is formed and welded.
Aluminum Corona Shielding Sphere Wall Thickness Design
Here we should discuss the sheet metal and welding type aluminum corona shielding sphere wall thickness.
Wall thickness of bending and welding plate will be from 2.0mm to 20mm.
Usually the 2.5mm thickness plate is for 500mm outer diameter corona shielding sphere production and design.
The larger thickness sphere will have high strength.
In a word, the thickness of plate of corona shielding sphere will be designed and discussed with customers together.
Aluminum Corona Shielding Sphere Outer Diameter Design
Outer diameter of aluminum corona shielding sphere depends on high voltage grade on terminal bushings.
As the high voltage level of terminal bushing becomes higher, the diameter of the corresponding aluminum corona shielding sphere must be enlarged.
Here we should introduce our design and processing capabilities of the large outer diameter of these spheres and balls.
The biggest diameter dimension of one sphere is up to 6000mm.
During the aluminum corona shielding ball production process, our team will check the sizes frequently and input our Just-in-Time record.
This could ensure all aluminum corona shielding spheres are within the good manufacturing quality.
