Toroidal Terminal For Tesla Coil & HV Uses: 18", Highly Polished

Calculated at checkout

Product Description

Highly polished.

The high-polish of this toroid is useful for HV DC power supplies to prevent leakage loss. Note that you do not want a highly-polished toroid for use with Tesla coils, as there should be some air leakage in order to generate good sparks.

18" diameter x 4.5" height spun aluminum with ¼" center hole.

These are spun aluminum of grade 1100-O (99% pure aluminum), with a welded seam that has been smoothed and polished and cannot be seen. Aluminum wall thickness is approximately 1/16" (so the flat central area is about 1/8" thick, for example). Excellent for high voltage DC generators.

Our laboratory has the tooling and now offers many sizes of toroidal terminals: have a look at our PDF sheet to see other available sizes from 3 to 98 inches!
