NEMA Publishes ANSI/NEMA C29.11-2012 American National Standard Composite Suspension Insulators for Overheard Transmission Lines—Tests


The National Electrical Manufacturers Association (NEMA) has published ANSI/NEMA C29.11-2012 American National Standard Composite Suspension Insulators for Overheard Transmission Lines—Tests.    

A composite insulator is made of at least two insulating parts—a core and a housing. ANSI/NEMA C29.11 is a manual of test methods to determine the characteristics of composite electrical insulators that are defined within the standard.

According to Rob Christman, chair of the ASC C 29 Committee, other C29 standards refer to the general test procedures outlined in in ANSI C29.11 in designating test methods for specific types of electrical insulators.
