ROSSLYN, Va.—The National Electrical Manufacturers Association (NEMA) published ANSI/NEMA WC 75-2015 Standard for Controlled Impedance in Internal Electrical Cable. This standard was developed to cover specific requirements for finished cables with controlled impedance twisted pairs. It enables a user to specify various numbers of pairs (1– 61) with a required impedance requirement, and tailor the materials to meet a specific end application. The cables are intended for wiring of electrical equipment.

ANSI/NEMA WC 75 was developed by the NEMA 7HW Aerospace Technical Committee, and is for the defense industry, aerospace industry, and other high performance applications.

ANSI/NEMA WC 75 -2015 is available in hard copy or electronic download for $68 on the NEMA website.
