Toroids
Eastern Voltage Research is proud to offer the most beautiful seamless spun aluminum toroids available anywhere in the world. We offer some of the most popular sizes for Tesla coils, high voltage dividers, and other high voltage equipment. We also have tooling to produce more than 75 different sizes of toroids ranging from 3" to 98" in diameter. All of our spun aluminum toroids are spun using grade 1000-O (99% pure) aluminum with a welded seam that is extremely smooth (the seam) and completely invisible. Note, toroids are no polished - they feature a high quality aluminum brush finish.
The sizes featured here are some of the more popular sizes that generally fit a wide range of applications from small to medium size Tesla coils, high voltage dividers, and other high voltage terminals.
We also carry a full line of corona spheres and spark gap electrodes.
