Aluminum Corona Rings Factory Suppliers & Manufacturers China

Every aluminum corona rings factory saying that they are the best has sort of becoming a cliché. You could find many corona rings manufacturers that say that their methods make them the best supplier there is.

Technically, we are discussing the exact same thing now.

We’re about to say that we are the masters when it comes to designing and manufacturing aluminum corona rings for many advanced companies. What’s more, we have some viable reasons that prove this fact and back up our claim.

So, without further ado, let’s get into a few reasons why our corona rings products and our HIGHV factory are the finest choices in the global markets.

Before view more information below, just ask yourself a question: Which company would you hire?

Would you hire a corona rings factory that’s just starting off or a company that’s been up and running and serving some of famous brands around the world?

Here Below Video Is The Introduction Of HIGHV’s Advanced Production Technology:

The answer there is pretty obvious.

Our aluminum corona rings factories are ones that have been in business for over 28 years and have served more than a few of the fortune 500 companies and advanced high voltage research institutes in the entire world.

ABB, SIEMENS, HITACHI, TOSHIBA, STATE GRID and CHINA SOUTHERN POWER GRID are just a few of the thousands of names. Welcome more testimonials and cooperations from our customers.

We are the folks they turn to for all of their precision aluminum corona rings needs.

We are highly trusted by these names and they never hesitate to offer their gratitude for our services. As the famous saying goes, Great minds think alike. So, if the top companies are using our services, that is a clear sign that maybe you should as well.

2. Our Powerful Mould Production And Corona Ring Design Ability

The mould of aluminum corona ring refers to the tooling used to produce ring in molding. Traditionally moulds have been expensive to manufacture and were only used in high-volume production applications where thousands of aluminum parts were produced.

In the past years, our factory has helped many customers projects with rich experience. So the customized rings moulds are on our stock.

The three main design parameters of corona ring which determine the magnitude and location of maximum surface electric field are aluminum corona ring outer diameter, corona rings tube wall thickness and distance of aluminum corona ring from the high voltage end.

If designing the aluminum corona rings still seems overly complex, the best thing to do is consult an design and manufacturing expert.

HIGHV is one such specialist, with years of experience creating aluminum corona rings for a range of customers.

We are able to design, develop, produce and deliver aluminum corona rings according to customer detailed drawings, samples or just an idea.

We offer a reasonably priced fabrication service, with corona shielding components available in a range of aluminum alloy, copper and stainless steel.

3. Our Aluminum Corona Rings Products Are Durable, Good Corona Shielding Effect And Light Weight

When you are looking for stable suppliers of corona rings, the first thing should be considered is the competitive price.

To be honest, the price can impress a lot.

Let’s get into a bit how we excel in all three departments.


We choose high quality aluminum raw materials ensure that our corona rings products have high strength and anti-causticity.

They can bear the high voltage impulse test without any problem.

We ensure that our customized corona rings can be used for fields a lot heavier not for lip service.

Good Corona Shielding Effect

Generally the corona rings need to be polished bright to achieve more smooth and no burr surface finish for ensuring better corona shielding effect.

There are also another one factor which can influence the corona shielding effect.

As the high voltage level becomes higher, the diameter of the corresponding aluminum corona ring must be enlarged.

Corona ring with a larger outer diameter is better for corona shielding effects of tests.

Here we should introduce our design and processing capabilities of the large outer diameter of aluminum corona rings for power transformers.

The biggest diameter dimension of one ring is 16000mm. And pipe inner diameter of ring is 3000mm.

Our corona rings products have great surface finish to ensure that every high voltage project runs smoothly.

Light Weight

Not much we can say about this. Aluminum alloy material is obviously lightweight.

Even though we put quite a lot of attention on the design and production aspect, our products remain lightweight and easier to carry and transport.

4. Our Aluminum Corona Rings Factories Have The Most Helpful Customer Support Ever

Just like any other customer support, ours is also meant to “support” the customers.

But, trust us when we say this, you haven’t seen customer support until you’ve seen the one at HIGHV.

We can answer any queries or follow up questions that you might have. You can call us to request quotes and we’ll get back to you in 24 hours with the exact price for our service.

Are you looking for 2D and 3D designs of the aluminum corona rings that you’re going to get?

Don’t worry about that. And you can request a complete CAD or 3D drawing before we get to the manufacturing phase.

We can have your CAD and 3D designs ready in just one day and have the product delivered to your hand in just three weeks.

5. Our Variety of Customized Corona Rings For Industries
