Looking to find MFG for large corona rings
(OP)
Anyone know a company capable of making large corona rings. We are looking for 8"ODx.25wall tubing made into 44"OD rings. We are looking to purchase 18 of these and I cant find anyone willing to make them for us. Any help appreciated.

In test lab, we use corona ring of size as mentioned in your mail at a tiny fraction of the cost mentioned by you.We use flexible aluminum air duct used by air conditioning industry.www.aeroflex.co.in. It works to carry connecting leads.When PD test was started on Power trfs during 1960's GE was using cartyre tubes as corona ring in their factory in your city.
If you want permanent set up,then also I may be able to suggest you low cost sources from India.

As far as flexible air duct I dont think the surface is smooth enough without testing the material. Unfortunately I have a customer that wants to purchase the corona rings assemblies asap.
It is for permanent outdoor application at 500kV.
thanks
