Pin Types

Standard ANSI Standard Designs

  Victor manufacturers three classes of pin type insulators. Low voltage pin types are manufactured and tested to the requirements of ANSI Standard C29.5, high voltage pin types to ANSI Standard C29.6, and special designs for use in areas of high contamination. All Victor Pin Types are RUS accepted where a specific RUS classification exists. Standard color is sky gray, with chocolate or white available upon request. Standard products are radio free treatment (exception Cat. No. 35 fog bowl).

Low Voltage Pin Types (ANSI Class 55-2 –¬†Class 55-6)

These insulators are all single piece designs with porcelain threads, a design which years of field experience has proven to be the best. Victor Insulators lead the way in developing and introducing this design concept to the marketplace.

* Typical application voltages are intended as a guide only and may be affected by service environment or other factors. Please consult factory if more information is required. Catalog numbers with suffix R are radio freed. For non radio freed (plain) insulators omit the suffix R from the catalog number.

High Voltage Pin Types (ANSI Class 56-1 – 56-4)

High Leakage and Fog Bowl Pin Types (Special Designs)

These insulators have been designed by Victor to meet specific customer application needs in areas of extreme service conditions due to contamination. Fog Bowl designs offer high protected leakage areas.

While no ANSI Standards exist for these products Victor manufactures and tests each of these insulators to meet the general requirements of ANSI Standards C29.1 and C29.5 to ensure quality and a lifetime of trouble free service.

Due to the unusual service conditions that these insulators experience, typical application voltages are not given. The factory should be consulted to determine the appropriate insulator for use in a given application.

All insulators are designed with standard neck dimensions so that pre formed (wrap lock) ties may be used.
