Steatite insulators are very efficient at high frequencies and voltages where other materials often fail.

Our facilities are adaptable to manufacture large and small quantities, and we offer two grades, rated by electrical performance.

We can also offer different grades of alumina, insulators and assemblies complying with military specifications, clear and brown glaze finishes, and insulators marked with part numbers or company names upon request.

Which steatite ceramic insulator is right for you?

To assist electrical engineers in making a decision as to the electrical and mechanical suitability of Isolantite insulators, we present these properties.

Feel free to direct questions relating to the nature or meaning of this data toward our engineering department so that a suitable and economic selection can be made. For most standoff and suspension applications, Grade L-5 steatite is supplied as standard.
