ROSSLYN, Va.—The National Electrical Manufacturers Association (NEMA) published NEMA WC 76-2018 Standard for Controlled Impedance Shielded Twisted Pairs in Internal Electrical Cable. This new Standard enables a user to specify various numbers of shielded pairs with an impedance requirement as well as tailor the materials to meet a specific end application. The cables are intended for wiring of electrical equipment.

"Original Equipment Manufacturers (OEMs) have for years needed to write their own documents to allow them to purchase controlled impedance pairs for their specific application," said Kevin Coderre, Technical Director, Marmon Aerospace & Defense, and Chair of the NEMA Aerospace Technical Committee.  "This document will become very popular as it allows OEMs to easily specify various combinations of shielded pairs and insulation materials to meet specific end applications."  

This Standard is useful for the defense industry, aerospace industry, and other high-performance applications.

NEMA WC 76-2018 is available in hard copy for $69 and as an electronic download at no cost on the NEMA website.
