Corona Shielding Ring Packaging & Shipping

customized flexible packaging capabilities
  • Highv has professional packaging team who can adopt developed packaging technology and packaging style to ensure the corona shielding ring packaging quality.
  • Standard sea packing, the corona shielding ring packaging can be done by wooden case and carton box. The wooden case and corona shielding rings contact parts must be padded with foamed paper or rubber. Wooden case four corners shall not be smaller than the size of the corona shielding rings. Corona shielding ring’s surface is wrapping foam paper, and four sides contacting with wooden case with foam mat protection.
  • In addition, clear labels are tagged on the outside of the packages for easy identification of the corona shielding rings measurements and quality information.

*Other special packaging will be designed as customer’s request

What Are Corona Shielding Rings?

Corona shielding ring, it is also known as corona ring or electrode, which can be divided into arrester corona shielding ring, lightning protection corona shielding ring, insulator corona shielding ring, transformer corona shielding ring, high voltage test equipment use corona shielding ring, power transmission line corona shielding ring.

Corona shielding ring or electrode can be used in precision measurement of electrical equipment. HIGHV offers designing, manufacturing and installation of corona shielding ring.

How Do Corona Shielding Rings Work?

A corona shielding ring, also called an anti-corona ring, is a toroid of conductive material, usually aluminum alloy, which is attached to a terminal of high voltage equipment.

The role of the corona shielding ring is to distribute the electric field gradient and lower its maximum values below the corona threshold, preventing corona discharge.

Corona shielding ring is used on untra high voltage power transmission insulators and gas insulated switchgears, and on scientific research apparatus that generates high voltages.

Corona shielding rings are typically installed on super high voltage power line insulators.

Corona shielding rings prolong lifetime of insulator surfaces by suppressing the effects of corona discharge.

Corona shielding rings may also be installed on the insulators of antennas of high-power radio transmitters.

However, they increase the capacitance of the insulators.
