Applications

The NEMA WC 55021 Specification is used to describe both shielded and unshielded cable constructions for internal wiring for electronic equipment. The specification allows the user a wide variety of construction choices. Circuit identification, conductor size, insulation type, number of conductors, shielding material and jacket compound may all be specified using the document. Single conductor, twisted pairs, triple, quad, quintuple and multi-conductor cables through 5 components are all included.

Marmon Aerospace and Defense® is able to provide a wide range of NEMA WC 55021 constructions. Although the website cannot list all the detailed testing and specification requirements contained in the complete NEMA WC 55021 document, we have summarized the major construction features of the specification and listed those that Marmon Aerospace & Defense® produces. Please refer to NEMA WC 55021 for complete performance details.
