ROSSLYN, Va.—The National Electrical Manufacturers Association (NEMA) published ANSI/NEMA HP 9-2014 Electrical and Electronic Ethylene-Propylene Diene Elastomer (EPDM) Insulated Hook-Up Wire, Types EP (rated 125°C;600 V), and EPD (rated 125°C;5000 V). This standard is useful in the defense and aerospace industries, as well as other high-performance applications.
HP 9 was developed by the NEMA Aerospace Technical Committee (7HW), and covers specific requirements for ethylene propylene diene elastomer (EPDM)-insulated solid and stranded wire designed to the internal wiring of high reliability electrical and electronic equipment. It addresses 600 volt (Type EP) and 5000 volt (Type EPD) wire, and permits continuous conductor temperature ratings of -25ºC to +125ºC with tin-coated conductors. These types of hook-up wires are used when the following are required: moderate temperature resistance and good flexibility and flex life when stranded conductors are used.
“EPDM offers excellent dielectric strength and is more flexible than a polyethylene or polyolefin, making this standard an excellent choice where flexibility and dielectric strength are critical,” said Kevin Coderre, Technical Director at RSCC Aerospace & Defense and NEMA 7HW Aerospace Technical Committee Chair.
HP 9-2014 may be downloaded $75 or purchased in hard copy for $75 on the NEMA website.
