Spherical Metallic Terminals

We now can supply you with spherical metallic terminals for your projects. Not only do these pieces offer aethestic value they also provide an amount of capacitance for enhancing the output of Tesla coils and supply the surfaces necessary for reducing leakage in high voltage dc sources. All have 3/8" mounting holes (not threaded). View free PDF sheet for other available sizes up to 65 inches!

SHP4STEEL - 4" Steel Spheroid, Good Up To 140 kv...................$9.95
SHP2BRASS - 2" Steel Spheroid, Good Up To 70 kv....................$9.95

Toroids

Our laboratory has the tooling and now offers many sizes of toroidal terminals from 3 to 98". These are spun aluminum of grade 1100-O (99% pure aluminum), with a welded seam on sizes above 12" that is smoothed and polished and cannot be seen. Excellent for Tesla coils requiring a capacitive terminal and high voltage dc generators up to 1.5 million volts. Download free PDF sheet for other available sizes from 3 to 98 inches!

Aluminum Oblate Terminal

We now can offer the high voltage researcher a 14-inch terminal that supports up to 500,000 volts. The 14" oblate has a 3-3/4" hold for mounting onto an insulated column and can be used for the collector terminal of a Van de Graaff generator. Note that some may have a minor dent that will not impair operation but may be removed for aesthetics.
