NEMA Publishes Electrical and Electronic FEP Insulated High Temperature Hook-Up Wire, Types KT, K, and KK Standard

The National Electrical Manufacturers Association (NEMA) published ANSI/NEMA HP 4-2012, "Electrical and Electronic (Fluorinated Ethylene Propylene) FEP Insulated High Temperature Hook-Up Wire, Types KT (250V), K (600V), and KK (1000V). ANSI/NEMA HP 4-2012 covers specific requirements for FEP insulated solid and stranded wire, designed for the internal wiring of high reliability electrical and electronic equipment. This publication addresses 250V (type KT), 600V (type K), and 1,000V (type KK) wire and permits continuous conductor temperature ratings of -65°C to +200°C with silver-coated or nickel-coated conductors and -65°C to +150°C with tin-coated conductors. These conductors are used primarily in insulated wires for aerospace, electrical, electronic and other high performance applications.

ANSI/NEMA HP 4-2012 is available in electronic or hardcopy format for $58. To purchase, visit NEMA’s website or contact IHS by phone at 800-854-7179 (within the U.S.) or 303-397-7956 (international), or visit
