Aluminum Corona Shields Packaging & Shipping
The corona shields packaging can be done by wooden case or carton box.
Wooden case packaging is suitable for heavy weight ones.
Carton box packaging is always for light weight shields. It is also convenient for delivering by hands.
In addition, clear labels are tagged on the outside of these packages for easy identification of these shields or rings measurements and quality information.
The big and strength pallet will be used for placing the cartons boxes. It will help packaging more stable during the shipment.
Because of the limit and customs requirements of various countries, so non-fumigation wooden pallets are widely used for carton boxes base support.
*Other special packaging will be designed as customer’s request

What Are Aluminum Corona Shields?
Series resonant system produces high voltage, which cause the non-uniform local electric field. The function of the aluminum corona shield is to make the local electric field be uniform.
The corona shields are used in high voltage testing equipment and power systems (substations, high voltage bushings, AC/DC voltage systems, circuit breakers, etc.) and are mainly made of aluminum alloy and copper. Generally the corona shields need to be polished bright to achieve more smooth and no burr surface finish for ensuring better corona shield effect.
What Materials Can Be Used For Grading Rings?
With the development of technology, aluminum alloy for shields production has become the current trend. The use of aluminum alloys to make these products has the following advantages:
- The overall weight of the cargo is reduced, which is suitable for insulator installation
- Aluminum alloy also has the hardness and strength of some metal, which meets the safety standards of manufacturing
- Compared with normal steel, aluminum alloy has stronger oxidation resistance
The Features Of Aluminum Corona Shields
- Material: Aluminum Alloy
- Operating Temperature: -80° C-80° C
- Polishing Bright Surface Finish
- Preventing premature electrical breakdown
Applications of Grading Rings
HIGHV custom made solutions and Aluminum Corona Shields are widely used for below different fields:
- Insulator

What Are Aluminum Corona Shields Surface Treatment?
Usually the polishing silvery bright is the final main surface finish of aluminum corona shields not only for the indoor high voltage bushings but also for the outdoor testing issues.
The surface finish roughness is Ra3.2. The corona shield production process is according to DIN ISO2768-MK general tolerances.
Other manufacturing standard includes general tolerances for welded constructions, tolerances for lengths, angles, tolerances for shape and position, etc will be in accordance with EN ISO 13920-B-F.
Other surface treatment can be done here. Such as anodic oxidation, galvanized, color painting and coating insulating varnish.
