Aluminum Corona Rings For Power Transformers: The FAQ Guide

Aluminum corona rings are the basic and important parts on corona control project. Aluminum corona rings are mainly used for power transformers and high voltage laboratory. It is easy to operate, convenient to move, and fast to install.

Here let Highv team introduce aluminum corona rings for power transformers. Then you will be able to get a clear and a crisp understanding of that.

Power transformer is a type of equipment used primarily to receive low voltage generator electric power and transmit it across distribution channels across the power grid network.

It forms a crucial part of the power grid and helps in transmission of power from one network to the other without change in frequency.

Power transformers operate at peak load and are designed to have maximum efficiency at full load.

Decades of research in the transmission networks has led to an increase in the transmission voltages. Power transformers enable the power transmission low-voltage to high-voltages.

Power transformers can help integrate new renewable power plants to the existing transmission networks.

What’s more, the emergence of renewable energy as a primary source of energy offers long-term growth opportunities to the global power transformers markets.

What Are Power Transformers Functions

Power transformer is an electrical equipment consisting of two or more windings, which are connected in the same magnetic field.

These iron cores do not conduct electricity, but they are magnetic conductivity.

The role of the power transformer is multi-faceted not only to increase the voltage and transfer the electric energy to the electricity consumption area, but also to reduce the voltage to the voltage used at all levels to meet the needs of electricity.

In short, both step-up and step-down must be completed by the power transformer.

In the process of transmitting electric energy in the power system, two parts of voltage and power will inevitably be lost.

When the same power is delivered, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage.

The power transformer is used to increase the voltage and reduce the transmission loss.

Why Do Aluminum Corona Rings Work For Power Transformers


High voltage can result in unwanted noise and corona, especially in the high voltage power transformer test which voltage is ultra high.

So aluminum corona rings are needed to suppress the corona during high voltage testing process.

Aluminum corona rings are common parts in power transformers.

They are easy to operate, convenient to move, and fast to install.

As you know, a lot of corona rings are used in power transformer which ensures testing project to run more smoothly, efficiently and safely.

When it comes to your power transformer testing project, aluminum corona rings from Highv can help you finish all corona shielding solutions.

One of the main factors is the outside diameter of ring body, which have the main influence for potential gradient and corona effect on power transformers. Some end users need more larger diameter rings for their project.

Here we should introduce our processing capabilities of the large outer diameter of aluminum corona rings.

The biggest outer diameter dimension of super aluminum corona ring is up to 16000mm.

And pipe inner diameter of aluminum corona ring is 3000mm. Wall thickness of pipe will be from 2.0mm to 10mm.

During the production process, our team will check the sizes frequently and input our Just-in-Time record. This could ensure all corona rings are within the good tolerances.

How To Design Aluminum Corona Rings For Power Transformers Project

Aluminum corona rings design is the basic and important part on power transformer project.

  • At first, our professional engineers team will help customers choose the right material of aluminum corona rings production. Different grade aluminum materials have each advantages and functions.
