NEMA WC 75:2015

This standards publication was developed to cover specific requirements for finished cables with controlled impedance twisted pair(s). This standard uniquely 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. Cable covered by this specification is intended for use in the hook-up of various electronic assemblies. Cables constructed with PVC insulated wires or jacketing are not to be used for aerospace equipment.
